Some 40+ people participated in the impressioning championship. In the first round, one lock needed to be impressioned within an hour. The locks were sponsored by Abus and they gave us keyed-alike cilinders with a rather shallow profile. Within the hour, 32 people opened their lock.

The 6 fastest went on to compete in the A-final, the 6 runners up in the B-final. Both groups needed to open 6 locks in less than 15 minutes each. These were locks with more difficult profiles.

The result:
A-Final
1. Manfred
2. Jan-Willem
3. Jord
4. Walter
5. Cocolitos
6. Jos
B-Final
7. Alex

For the 11th time in a row, Toool has organised LockCon, the international conference on lock sport. Before that, it was the Dutch Open Lockpicking Championship, and this championship is now incorporated in LockCon, together with an impressioning competition and a leverlock competition.

With over 100 attendees last weekend, it was bigger than ever, but it still retained that cosy family get-together feeling. Information sharing, meeting up with old friend, meeting new friends, swapping locks and participating in championships in a relaxed environment, where everybody participates in making it a success is what it’s all about.

It was nice to see delegations from all parts of the world, from nearby to far away (even including Canada, US, Australia, New Zealand).

The Italian delegation brought in a fine selection of Parma products, including wine, ham and cheese.I would like to thank our sponsors, beginning with Abus, long-time sponsor of the many locks and blank keys for the impressioning competition. Datagram sponsored the badges and trophys. All the prizes were sponsored by Sparrows, Multipick, TOKOZ, PACLOCK, Parmakey, M2 serrurerie and Oli.

S&G 0881I must admit I did not know the lock, aklthough it is apparantly well-known in the USA. The lock is made to especially withstand harsh weather for prolonged periods and still open without problems,

L0ckcr4ck3r has worked his magic to cut the lock open and this is the result:

Czech Lockpicking Championship 2019 by the Association of Czech Lockpickers.
Website: www.lockpicking.team

Report by Jan-Willem.
On Uklocksport Meastro posted an open invitation for lockpickers to compete in the championship. The topic is a good read, you’ll find a lengthy discussion about the rules and difficulty of the locks. I’ve decided to join the competition and booked my flight.

The conference started on Thursday evening. I flew in on Friday and missed every easy method to get to the conference easily. I’ve haggled with the taxi driver and he took me to the conference. It took 90 minutes and was the most expensive taxi drive I’ve had to date. The Taxi driver did not speak much English and told me he was a diving instructor. From driving I understood he was a rally driver too. Just before dark I arrived at the location. The competitions had started earlier and meant I missed the padlock competition.

Main building at Youth camp Nova Zivohost The conference was held at the youth camp at Nova Zivohost with many small cottages close to the river. The competition was held in a large cafeteria like room on wooden pick-nick benches. Even the most basic accommodation was more than sufficient. I’ve slept in a small cottage with bathroom on 200m.

Moldau at Youth camp Nova Zivohost The championship has many disciplines; from padlocks to cylinders to impressioning. Each competition had it’s own timetable, rules, and dedicated crowd. In between the competitions there where talks on various topics, from safe locks to decoders and lock patents to locksport groups. At the competition I’ve participated in Imperessioning, group 2 safe locks and freestyle.

The prices on displayTo get to know each other every lockpicking group had 15 minutes to tell what they achieved. Many nationalities where present. Not limited to: Italian, Czech, Hungarian, German, Austrian and Dutch. I’ve done a small and improvised talk on Toool, shown off a few fun projects like ‘the room’ at HackerHotel. The talks took quite a while as everything was translated from Czech to English and English to Czech. I’ve Marek to thank for translating every little detail.

Impressioning was my first competition. The pick-nick benches where a bit annoying as I could not get the right angle. I’ve brought my block-o-wood vice with me and it did work perfectly. In the first round we got one lock and 5 counted blanks. I’ve opened mine in 90 seconds and proceeded to te finals. After 7 minuted eight people opened the lock, four for each final. The rest was not allowed to proceed. All the blanks where counted, all of them needed to be returned.

Jan-Willem at the impressioning championshipFor the finals there where some extremely difficult locks. Fab 200, Fab 1000, Tokoz tech and Evva are no joke. These locks are restricted and wherefore I was not allowed to keep a lock, a blank or a even a photo of the locks/keys.
It was unexpected and quite annoying. I’ve managed to open one and it was enough to win the competition.

Impressioning setup.I’ve entered the freestyle competition and it was a lot of fun, 5 minutes a lock. All tools allowed. Some of the locks where impossible and to me did not have a place in the competition. This included the Stealth key, Multilock and Xsecure (dimple). None of these locks opened on my table.

For the group 2 safe manipulation we had one hour to crack a S&G safe lock. Out of all competitors none opened the locks. I did not enter the Blitz (30 second knockout) or Cylinder competition. I used this time to talk with others at the conference. Many people have a story to tell if you talk time for them.

Table full of lockpicking equipmentThe competition was a lot of fun but there are plenty of improvements to make. For me it all comes to communication. If you expect something from me, please ask and don’t just assume. The competitors where largely overestimated this meant that some if not all competitions where harder than necessary. Only 2 out of 16 opens in impressioning. Zero openings in group 2 safe manipulation. Harder does not equal better or more fun.

I would like to ask to value competitions equally. Cylinder lockpicking was the larger competition. That does not mean it takes less effort to win freestyle, padlock or impressioning.

Thanks to the Czech team for organising this event. Please check www.lockpicking.team for the next event. 2020 will be LockFest and 2021 the next championship.

Certificate for winning the Czech impressioning championship

I’ve recently acquired ~20kg lockpicks, 4000 lockpicks. These where sold by a scrap metal dealer on eBay. As why he had them I can only guess. He did well for not scrap these. The picks are a bit rusty and need work to be useable. As you can imagine cleaning them all by myself will not be fun. There for I decided to sell most of them and give some away. (Yes, this project is not what a sane person would attempt.)

I’ve sold bags of 500g at LockCon. Most will be used at lockpicking villages around Europe. With the remaining picks I’ve created grabbags of about 250gram (50 picks) for the Dutch Hackerspaces. Because every Hackerspace needs lockpicks.

Lockpicks, ~4000 of them!Lockpicks packed and labelled. Ready to be shipped by Hackermail (Inter-hackerspace delivery service)The full story can be found on: https://bitlair.nl/Projects/Lockpick...h_Hackerspaces Happy picking!

‘Le Corbeau’ outils d’ouverture fine are lockpick makers in France. You’ve likely seen the lockpicks before. Picks with a hummingbird style handle. Recently they wrote in an article that they will resume making picks shortly. They also announced a new pick design more on this later. I’ve bought a set from them a few years ago as the pick designs are interesting. Example: https://www.ouverture-fine.com/54-corbeau

As the story goes they’ve designed something special for 2020, a new one of a kind lockpick design. It’s a Half Deforest half double ball. If it stands up to the testing they’ll produce it. What do you think?

Half Deforest, half double ball by ‘Le Corbeau’ outils d’ouverture fine. https://www.facebook.com/OutilsLeCorbeau/posts/3047366965277981
‘Le Corbeau’ only communicates by Facebook. If you are interested in the design send them a message.

Once in a while people bring very interesting locks to our meetups. In this case an ignition lock from a classic car. The task was clear: impression a key for this lock. Taking this lock apart would pose serious challenge and risks.

As the ‘job’ was not announced in advance we had to make do with what was on hand: steel blanks, imperfect magnification, and an old file.

Complete ignition lock. The back of the lock. A working key! Do you want to learn how to impression a lock? By special request we can bring the impressioning gear to the meetup. It’s not something we carry standard because of volume and weight.

Toool NL has created a Discord server to keep in touch with other lockpickers in The Netherlands and meet new people in locksport. If you are interested in joining Toool or just want to chat about locks, please join and meet us on the Discord server.

Discord is a text based platform similar to IRC and Slack. It is not a forum where discussions are grouped into subjects and threads. Discord uses categories and channels instead. The style suits better suited for ongoing conversations or for fast pase communication than in depth discussion on a topic. Discord is not limited to text and can also be used as video chat or sharing photos.

Toool UK has a Discord server for several years with great success. The Toool NL server is live from January and is now open to the public.

Link: https://discord.gg/4exGbZm3QC
Create a Discord account. Click the invite link. Complete the CAPTCHA and write a short introduction in #introduction. The member role will be added manually, please be patient as we are not on Discord 24/7. Toool members are asked to register and send a mail to the board with the full Discord username. You can call it a 2FA.

On the server we have different roles and privileges. From member, trusted member, board, and admin. It is not the goal to gate keep but it is useful to limit accessibility to some content for newly joined. This will for instance protect against bots, scraping or spamming the server.

Do keep in mind Toool does not host the server. Do not post things on the internet that should not be on the internet. Not limited to: Personal details or secret research.

Hope to see you on the Discord!

-------------------------------------
In 2019 Jan-Willem started with am odd collection. Not the locks, nor the keys, just the pins from a pin tumbler. Pins are in a lock and make them function. However, the pins are only observable when the owner decides to gut the lock or create a cutaway. The idea was simple: Create a collection/archive of pin tumbler pins and their keys. This required a proper way to store the pins.

To store the pins many different boxes have been tried. After many failed attempts Jan-Willem stumbled upon a hobby not to dissimilar from our own: coin collecting! The value of one €2 coin is just €2 to a consumer. While the collector is looking for a 1st edition misprint from Monaco, and not just any coin.

Coins are often stored in albums, either with or without protection. The lowest quality coins protection are two pieces of plastic film and a cardboard cutout. Often glued or stapled together. While the high end coins are with a certificate sealed in an acrylic case. Leuchtturm makes coin boxes in between the two, and at a reasonable price and the inserts are DIY, lasercut acrylic.

First attempt with Leuchtturm boxes.To store these boxes it was decided to use business card holders, this did not go as plan and required custom holders. First made from acrylic and the second version from wood. Fifty sets of pins are created and thirty are added to the album. This is where the project was stuck for a year.

Pins in album v1Last week was a good time to continue this project. A proper pleader album was bought. And the pins are added.
This is the result this far:

Abus E90 pins in a box.Leuchtturm album.Pins neatly stored in the album.The album has 48 pins and about 30 more sets are ready to be archived. Acrylic is ordered and the inserts will be created when a lasercutter is accessible again. The photos will be published here on Blackbag. For now you can find one key a day on twitter: https://twitter.com/hashtag/microkey...g_click&f=live

The coin boxes, album, and inserts are sold under the name Leuchtturm and Lighthouse. These boxes are available on eBay. Link to a Dutch web shop: https://www.knm.nl/leuchtturm-quadru.../product/2741/

In a previous blog post Jan-Willem’s pin collection was mentioned. In this post the pictures of the pins and keys are shared.

There is no epic conclusions to this project. At this moment it’s is just a collection of photos of locks and pins. Shared with the world. Hopefully it’ll be a resource for new pickers that would like to know what they are up against. Maybe future research will use it. Where someone clever uses the fact some spools are different than others to decode the lock. Sputnik comes to mind and we think the possibilities are not exhausted yet. (If you are working on something I’m happy to assist.)

New pickers, don’t be intimidated by the key or keyway. If you look through the collection much of the pins are underwhelming. Where a Evva is known to be difficult lock it was not expected to find all standards or one spool pin. When struggling with a lock just take it apart and see what’s in there. For the next time you encounter the same lock you will know Nemef has a spool on position two (insider joke).

This collection has a few obvious biases:

• The collection only contains basic pin tumblers.
• Most locks are from Europe, and are from well known lock brands.
• The locks are not too expensive and are usually old. Therefore it lacks fancy pins like gins and Christmas trees.
• Pins/locks that are too similar are rejected. There are some duplicates as well.
• This is a snapshot in time. The pinning of the locks change every few years. A good example is DOM RN with two different types of pins in this collection.

If you have specific knowledge on these locks. Please share, we are open to learning more about locks. Find us on Discord, leave a comment or send us an email.

The photos are: key, pins, key, pins. The photos of pins are arranged with the brand and number. The keys have ‘key’ in the name. The Titan with a key engraved D5474 will have the pictures: TitanD5474-1key-1-scaled.jpg and TitanD5474-1-1-scaled.jpg.

Once in a while we find locks for sale in bulk. Either as a large bucket or just a pile of brass. Most of the times it’s not worth the time and effort. (sorting and cleaning takes loooong). While other times the deal is just too good to pass on.

We bought a batch last week: Sold as 70kg of recycling brass. Seemed alight as it was not too expensive and the locks looked clean. It was also clear from the pictures that there wasn’t much high security or ‘expensive’ locks in there.

A few of these boxes/crates full of locks doesn’t look much until you need to carry them home.Nicely sorted Basi.All the locks!In total it’s about 400 locks: 20% BASI, 20% MD, 40% DESTIL, 15% other (DOM, Corbin, Nemef, CES, S^2, etc etc.), and about 5% trash (tags, screws, actual trash). There are very few jewels in the box: Anker necoloc, DOM sigma, and a keyed alike Zi-ikon set with one key.

Most will be put to restocking the lockpicking village kits. The Basi will make very nice progressive locks. The Destil, however, are (re-branded?) Corbin locks and always a pain to pick. Therefore a lot less useful for teaching lockpicking. (Maybe keep a few for teaching humility or patience?). All other locks will be saved for the Dutch open at the next LockCon.

As always the picture of the bucket looked more promising than the outcome. However, the easy locks will come in very useful. It’s just not as fun as finding a EVVA MCS in the crap bin. Maybe there will be one in the next one…

In 2019 Jan-Willem build a binding order demo out of laser cut wood.
In this post we would like to share the project with the rest of the world.

Binding order is the order in which the pins bind in a lock. This is mostly due to the manufacturing tolerances but can have other causes. This concept is hard to grasp for a new lockpicker and is one of those ‘You’ll get it when you see it’ concepts. When teaching lockpicking it is common to hear: ‘I have been pushing down this pin and it doesn’t want to stay down.’ This tool can be used to demonstrate why the pin did not want to stay put.

This demo is certainly not ‘the’ solution. It is just a fair attempt that works for us. It will make the explanation better by adding both the visual and touch to the explanation. The participants can play with the board and feel the effect of binding and what the effect is of using light or strong tension.

For reference: The board is about the size of an A4 piece of paper. The base is crafted from three layers of 3mm plywood. The core is a single sheet and the pins are three or four layers, depending on the feel you prefer. Each pinhole in the base/core has a different size and different offset. All of the pins are a different size er well. This gives plenty of options to change the binding order.

• 
• 
• 
• 

We used the demo in lockpicking villages across the globe. We have found that it helps the explanation immensely when encountering language barriers. Video link to how you can use the binding order demo: https://youtu.be/WiCdws84EuQ

The binding order in this model can be quite subtle. It would great to have another with extreme exaggerated binding order also a smaller, 3D printed version, would be great to have. A bit of paint will not hurt either.

Feel free to take the files and build your own. Attached you can find the Inkscape files:Download

Bought a safe; decoded; sold

-------------------------------------
This is a short story of me, Jan-Willem, buying a floor safe without a combination. Then failing to decode it, resorting to an alternative method, and eventually having to part with it again.

Let’s start at the beginning. I’ve found a rusty Major floor safe for sale online, without combo. The ad looked alright and the price was good. I miscalculated the drive and spend the next five hours in the car to pick it up. (Note: I live pretty cental and the Netherlands is not that big.)

The safe was also a lot heavier than anticipated and comes in at about 40kg (~90 pound). The safe door is about 8kg (17 pound).

Failing to manipulate
First up was cleaning the safe. The dial felt quite gritty and washed most of the sand away with lock spray from the WD-40 company. It worked quite well. It also created a huge mess in the safe but that was not my concern at the moment.

I’ll just say this outright: I’m not good at manipulating safes. I’ve beaten a few S&G but never beyond 6730 and 6741. Manipulating it was a pain as the space was tight and the dial didn’t show much. I must have spend 10h on it over a week and gave up on it.

Opening the safe, slightly destructive
When I have projects like this I want them done as soon as possible. I decided manipulating was not fun and resorted to the semi destructive method of drilling a small hole and use the key change hole to dial the safe open. I’ve used a 8mm (1/3th inch) hole and a 4mm (1/6th inch) camera. (Hopefully more about those in an upcoming blog.) The process was still quite painful but I’ve learned a lot from it. It did not take more than 60 minutes in the end.

As the camera is actually an integrated USB webcam I’ve recorded the process and shared for your entertainment. The short version is 82 seconds and the long version just over half an hour. [note to self: fix Word press so it embeds YouTube videos properly.]

Selling the safe
I’ve promised to share the full story so I’ll share a bit about selling the safe as well. These safes are quite rare here. From a quick search I’ve found a new safe door would cost me about €1k. Mostly shipping and import charges.

I love buying second hand goods. I search online and find an item, strike a conversation, place a very good bid, and pay minutes after we struck a deal. Selling on the other hand is extremely painful. (Hence why good manners work so well as a buyer.) For this safe I’ve taken plenty of detailed pictures, included all measurements, and put the safe up for sale. The difference between one buyer and another is clearly noticeable. Many people offered me to take the safe away for free or next to nothing and were offended when I said no. Finding a buyer took a few weeks.

The buyer asked for details on the change key mechanism and I’ve found the La Gard change key worked well. I’ve reset the combination to a random but valid combination. The buyer was unfamiliar with safes and how to operate them. We must have spend an hour on it. Instructing him how to dial the safe and he preformed the dialing a dozen times.

Just before the buyer left with the safe, afraid they would forget, they recorded them selves opening the safe. I’ve discussed this with a few locksmiths and it’s apparently normal. People, scared to forget, will take videos or involve spouse to help remember.

I’ve made a bit of profit on it, not including my time. Learned a few new tricks and have another story. I’ll think twice before buying another safe without combo but we know it’ll happen again.

Pictures
Lastly I want to add a few pictures for the archive. The lock is integrated in the safe door and can’t be removed or function without the door. The safe door has a cover that’s held in place with a large spring washer. Without the cover a relocker prevents the lock from opening.

Other than the circular nature of this lock it’s very similar to a La-Gard 3330.

The EVVA Dual is a lock with twelve spring loaded sliders and two sidebars. One on each side. It is an exceptionally hard lock to pick. Reinder Stegen, a gifted picker, found gutting of the Dual error prone and devised a tool to help with gutting the lock instead.

EVVA Dual with the correct key inserted. For a normal pin tumbler lock you can gut the lock once the plug rotates freely. This can, for example, be achieved by picking, back shimming, or using the key. The EVVA Dual can’t be gutted in the same way as a regular pin tumbler lock as the sliders protrude the cylinder both in the resting position as with the correct key. While the housing has grooves cut for the sliders to slide and rotate this also means that gutting the lock is much harder to accomplish.

EVVA Dual Gut Key moved the sliders down You will find more detailed pictures on the EVVA Dual on a recent upload to the Lock Wiki. http://lockwiki.com/index.php/EVVA_DUAL This wiki has been quietly expanding with lots of detailed pictures over the past year. Certainly worth a look at the Abloy Easy and the Chubb Mark IV Manifoil that are recently added.

Let’s get back to the EVVA Dual as that’s what this post was all about. The solution to gutting the EVVA Dual is this Gut Key (Set-up key for gutting) designed and 3D printed by Reinder. It solves the problem by moving the sliders down to the fictitious ‘shear line’ making gutting the Dual a breeze.
