Introduction: <a href="https://youtu.be/QpzXUxFTU0c">https://youtu.be/QpzXUxFTU0c</a><br /><br />In this video: The expected feedback that would reveal the difference between true and false gate is destroyed by a lot of &quot;noise&quot; from heavy friction between the wheels and the play between inner and outer wheel. Even after working on this lock for several hours I could get any usable information from the actual feedback.<br /><br />General information:<br /><br />Quote &quot; POLISH COMBINATION LOCK // New 100% Mechanical Combination Lock – Ultra Secure – 3.2 million unique combinations.&quot;<br /><br />The owner and inventor: Zbigniew Olejnik<br />Web site: <a href="https://www.polishlocks.com/">https://www.polishlocks.com/</a><br />youtube channel: <a href="https://www.youtube.com/channel/UCdgFa7Ur7q7sW38URiLCtUQ">https://www.youtube.com/channel/UCdgFa7Ur7q7sW38URiLCtUQ</a><br />playlist: <a href="https://www.youtube.com/watch?v=I8s3Ln9KdzY&amp;list=PLaQmDlBET810CDmLlX5gKCkrLg72z3NJ9">https://www.youtube.com/watch?v=I8s3Ln9KdzY&amp;list=PLaQmDlBET810CDmLlX5gKCkrLg72z3NJ9</a><br />The challenge-video: <a href="https://youtu.be/s_wCaYa5N5s">https://youtu.be/s_wCaYa5N5s</a>

Hallo Potti,<br />20**5 = 3200000 combinations.<br /><br />security doesn&#39;t improve by increasing the numbrer of FGs, but by the undistiguishability between TG/FG. <br />then they need to devise a mechanism to reset the beast, that may generate some feedback.<br />me think: there is nothing special that makes it unpickable.<br />bis Bald.
         Potti314 Potti314 21.06.2019->Guess a real metal version will give some more feedback. Its still far away from a production version yet.

Very interesting -- looking forward to next disassembly video. I like the concept and I would buy a production version.
         Potti314 Potti314 04.01.2019->Cheers and thanks for watching. The concept is nice and very creative but it needs improvements. Once a real model made from metal is made, we can tell more.

Great update on this lock Potti but, you really can&#39;t evaluate a plastic mock up version of this properly mate. As you know, materials like plastics and metals, can move or bend differently, as well as give different sounds or physical feedbacks. Still, a great lock no doubt, but we really look forward to seeing, you get a finished production article to test, rather than this plastic mock copy. Also, such other attacks on his metal version, may also differ too, but remain to be seen, as you can not directly test those theories, when applying them to different materials - even if their component parts are laid out the same? Still only a concept lock for us at the moment and, not really a proof of any concept, unless tested on the real thing - Case in point, cheap Chinese locks / clones, compared to real brands; they look the same on the outside, but are completely different, because they use cheaper materials like plastics, or Zinc etc. Also, their feedback is much different in a lot of cases, depending on what materials have been used. Not trying to put his lock down in any way, just merely saying, that not all thing will render the same outcomes, when it comes to materials used, to test a theory or give proof of something. Still, look forward to seeing your next video on this lock and, maybe the gentleman who sent this to you for testing, can send you a genuine finished versions, to test? You could also test the materials in both then, to see where their results differ? Nevertheless buddy, a super video on this lock and, thanks for sharing this update about it, with us all ???? Ps Sorry about late reply and, please don&#39;t take this funny in any way, for mentioning any of the above ? Just a viewpoint, that we thought is an important enough reason, for pointing this out. Thanks again buddy and, as I say, certainly not meant to come across as a personal attack, on the locks designer, who has clearly done a great job with this one ??
         Southampton Lock Picking Club Southampton Lock Picking Club 04.01.2019->@Potti314 Thank you and, as we say, not an attack on the designer; just need the finished product to test, for the reasons mentioned ??
         Potti314 Potti314 04.01.2019->For sure this model is not adequate for testing as it turned out. I was anxious to apply more pressure and break something. Also the operation is not smooth at all. He's trying to get metal prototypes made soon - let's see how it will turn out. But I have to admit that the tolerances (bar on the cam and gate) can be made pretty tight in that design without getting the internals seized up. Thanks for watching mate and for making a good point on that,

That is not a game about luck, the plastic is not an adeucate material to evaluate the decoding weakness of any design. If the designer is quite secure about his system, he will send you a padlock when he manufacture them in metal and you can face the challenge.<br />The design is interesting, but I&#39;m still betting on you without any doubt.<br />Cheers my friend and thanks for your effort and for showing ;o)))
         Potti314 Potti314 04.01.2019->He's currently investigating a way to get metal prototype builds done. Let's see how the look like and feel. My main concerns with the 3d model and also with the mechanism itself is the user-friendliness. You will this in the final video. Thanks for watching buddy and your your opinion.

Interesting.. Your right, pretty hard to get true feed back when the whole wheel pack moves around like that. I think this would need to be approached more like a Safe combo lock manipulation. Have you gotten into Safe lock manipulation yet? (I&#39;m just starting to get into it now) If so, perhaps a vernier scale could be used somehow. It would be hard to do with that many wheels stacked they way they are though. I wish I could offer more ideas or help, but I cant think of much more. You did great work though, don&#39;t sell yourself short.
         Potti314 Potti314 04.01.2019->I have no experience with safe cracking. I tries calibers but without success - not enough frictions between the metal and the plastic wheel.

I thought they were sending you a prototype of the Lock but that&#39;s more proof of concept than a prototype lock, and I feel it&#39;s characteristics would be so different than a Metal lock it&#39;s a pointless exercise you even trying to hack it, but it&#39;s nice of you to help him out with it.
         LockpickingBelfast LockpickingBelfast 04.01.2019->@Potti314 look forward to that video
         Potti314 Potti314 04.01.2019->After a tear-down which you will see shortly I can understand the issues with this plastic model. Metal will be much different for sure - and needs to be different to provide a proper user experience.

Man thats one ugly looking lock, sorry to be negative but it is an ugly duckling lol <br />I guess it would be a lot more compact made of metal tho.
         Potti314 Potti314 04.01.2019->Haha, it's a weird looking oversized lock for sure ;-) Looking forward to see the metal version once there is one.

An interesting design ,just a thought .If you test all five rings in a row against each other noting any obvious differences then without making any changes to individual rings,continue to turn all rings one increment each, test again and again until a full cycle of testing is complete. Would this reduce the number of combination possibilities and alleviate some of the friction issues ?
         Potti314 Potti314 04.01.2019->Sorry, but I couldn't follow your suggestion. But just testing an individual ring is difficult as you have seen.

Interesting. I was thinking though, that since each wheel has a false gate at each position, even if you could find the true gate, you would have to test just as many positions as a brute force attack starting at 0,0,0,0,0 and going up in increments of 1. Maybe same kind of bypass?
         Potti314 Potti314 03.01.2019->Yes, you have to test 5* 20 positions to get to the right number. But it's less than 20^5 in a brute force attack ;-) Will see if bypass is possible once I have opened it.

Wow would love to have one to keep It would look so good on my desk lol sweet lock and video
         Potti314 Potti314 03.01.2019->Thank you, it's for sure a very unique one.

Well you can&#39;t crack Them all but cool lock and you still have some time with it
         Potti314 Potti314 03.01.2019->Yes, I keep on thinking. Thanks buddy.

Awesome concept lock ? To be honest in my opinion when you have the metal one its going to have a different feedback for sure. Anyways well done ??? Bravo!<br />Someday I will gladly try to decide this padlock ?
         Potti314 Potti314 03.01.2019->Cheers, yes metal might be easier as smoother with less friction.

I think theres a way get the true gates from feel ... maybe try sliding a sleeve over the dials with a grove to fit the cut outs on dials .. so u can play with one dail goin anti clock while rest goin clockwise with the opening tension dial .. keep at it potti
         Shua L Shua L 05.01.2019->@Potti314 ok .. stop thinking its a lock and re think it as a safe .....time to get the doctor hearing scopes and go for sound decode?
         Potti314 Potti314 04.01.2019->I tried but not big difference.
         Shua L Shua L 03.01.2019->@Potti314 spray some lube in them dials
         Potti314 Potti314 03.01.2019->Thanks. I think the main problem is the friction between the wheels. I tried with other tool to move and stop the wheels but not luck yet.

By my opinion the main feature of this padlock is also it&#39;s major fault! It&#39;s a hard to remember 5 numbers from 1 to 20 in combination. For example, try to remember combination 18-4-12-19-6, especially if you do not open that lock on a daily basis! I also agree with @Enzo Guardino, that the metal version will give a better feedback.
         Potti314 Potti314 03.01.2019->I also think metal would make the lock work smoother which is desired for good user experience. This then will transfer the feedback more clearly, too. To remember the numbers is for sure a problem. On a usual safe lock it would be less to memorize.
