I've opened these before. It depends on the lock but the method I've had the best luck with is pulling and feeling out the binding wheel, then yank testing progressively through each number for that wheel until you hit the number you think gives the most, then identify the next binding wheel. Once you've maxed your give on the first two wheels, you can just brute force the last two wheels. If it doesn't open with a brute force at that point, then one of your first two are wrong. Switch to your second guess and start over.

I went ahead and opened one yesterday using both mentions that have been mentioned. One of those methods is very easy, and has been mentioned 3 times. I also tried to figure out a bypass, but I was unsuccessful.
This lock can be decoded with either method described. The harder of the 2 methods however, is not going to be done, or at least very likely done with a razor blade. Keep trying by putting tension on each end of the lock, and turning one wheel at a time, and stopping at a number when you notice it feels different to turn by that number.

yes, but i said 'randomly' it usually works faster on older locks.
