I am considering new setup 7 wheels but only 0-9 (ten numbers) on each knob. This padlock have 10 000 000 unique combinations. The body size is 60mm width x 35mm depth and 100 mm high. It is now ready for production. I need your support to start first metal version. Please donate any funds counts.
Here is how the heart on this mechanism would look like:

Hello, I would like to thank HelpfulLockPicker from USA for his great unboxing video. You can watch it here: https://youtu.be/i-xo_heHOJk
Please share this information widely. I like to share the new Polish Combination Lock mechanism with people. It is worth to think of it and understand its strong and weak points. I think the best way is directly through lock sports community.
I am working now on full metal prototype. This new mechanism will be examined by best in class people from sport lock community. The goal will be to find any weak spots before final design and production.
I am waiting for HelpfulLockPicker in-depth review coming soon.
Please stay tuned and do not forget that you can donate and support me.
Hello , this time small combination padlock with Polish Combination Lock mechanism inside is going to Swynndla for next review. This small padlock has very similar construction to previous lock however it works very smooth. You do not need any force to rotate the knobs and almost zero force needed to open it. It will be nice to see Swynndla opening this small padlock. It has in theory only 10 000 combinations but here due to 3D print limitations is only 1250 possible combinations therefore it is quite easy to open even going one by one.
Swynndla however will not go “brute force” but as in previous lock he would like to find the way to decode it. This is not 7 days challenge rather I asked Swynndla to do everything in front of camera since he unpack the lock till the final opening. In theory he should open it in less than one hour by going all possible combinations. I hope he will show his attempt and share his video with us.
The goal for me from Swynndla next review is to find out how ease is to operate this padlock. User experience of holding it and operate is the key for me to understand if anything should be improved here. Of course the numbers in metal version will be much more visible here the visibility is rather limited. This is no issue for me now. The most important is ease of operation and overall feedback. I hope Swynndla will like it as comparing to previous model this one operates without any force needed.
This small padlock has Seeger mounting ring (steel one) inside instead of the nut. This means Swynndla will not be able to change the code after opening it while special tool is needed to remove so small Seeger from the central shaft. Therefore fun is only one time game for him. I am very much interesting to see his impression about this small padlock and most important the user experience from operation, it will be all time pleasure because everything is working there without any special force needed.
This review would give me additional hints towards full metal prototype.
Current project assume that first full metal padlock will have 15 x4 knobs = 50625 true combinations (each knob could be rotated 15 times to change the code) and this is according to some experts enough for simple padlock.
I think that this time laser method will not works because of the size of this padlock but we will see soon what Swynndla will do with it.
Finally I have added some final words in my Next Step article:

11 July 2019 Swynndla has decoded my lock mechanism and therefore the challenge is over. You can watch Swynndla video where he explains how he decoded my mechanism. I would like to thank Swynndla for his participation, his passion and creativity in decoding. Here is his video: https://youtu.be/h1MYWwpqH2s
The mechanism has been decoded by Swynndla using a laser. In my thoughts section I have written what I think about it. I like to invite you to read the article “Next Steps“.
If you like my unique combination lock and you want to see it on the market please support me.

The Polish Combination Lock has been delivered to Swynndla.
He made his first video: https://youtu.be/S9fFSnUZJEg
Next round of worldwide decoding challenge just started. Swynndla has now 7 days for his decoding attempt. Good luck!
More information about global decoding challenge you can find here: https://www.polishlocks.com/the-worldwide-challenge/
Please help Swynndla if you have any idea how to decode my combination lock. You can write your comments under his video.
I am working now on full metal version of my Polish Combination Lock mechanism. Here is first concept visualisation. 4×15 code complication, 80x60x30mm body. More details will come soon. Still waiting for some feedbacks before final design.
Polish Combination Lock (white version) is now in USA and HelpfulLockPicker just received it. He will made his review very soon. HelpfulLockPicker is not participating in worldwide challenge. He received also the correct code in the closed envelope so he can play with my lock and then open it and show the inside. I would like to thank him for supporting me with his review and I am sure it will help to share this information and increase visibility of this unique mechanism.
Please do not pay too much attention to current design. Concentrate rather on mechanism and pros and cons about PCL combination lock mechanism.
Please visit my YouTube channel or watch more here.
Polish Combination Lock will be soon converted from printed 3D model to full metal production version. Please share this information widely.
