This is quite an interesting design for a combination lock. On the other hand, numbers may be easier to remember than directions. Many years later, I have now long since forgotten the game sequence, but I still remember the combination from a lock I used on my high school locker.
Why this? Why not go whole-hog and just make a playstation controller with a lock ring on it, so that all the idiots can do stupid things that only they find amusing, like setting their locker combination to fight-game combo moves? Locks only keep honest people honest. It makes sense to use them if only to prevent crimes of opportunity.
They do teach students to respect others. I was intrigued by the fact that it can have an unlimited number of movements. After a little research I found this comprehensive teardown and analysis. There are possible combinations which can all be reached by eleven or fewer movements.
So when you change the combination you can make it either easier or harder to remember than a standard three number dial padlock. Good find on the tear-down analysis. Not knowing the internal mechanism, I was a bit off with my guesstimate of the relative number of combinations.
As to everybody saying that locks only keep honest people honest. I live in an area that is proclaimed safe, but I still lock stuff. Could someone still get in? I dunno, but if I had 30 seconds to grab some items, I know I could, so I assume that with enough time, a crook could too. However, my neighbors all know me and have no hesitation in calling the police a mile away and a-looking for something to do to report anything hinkey.
Between that and my 80 lb dog with I-can-hear-the-mailmanhouses-away ears, I feel pretty covered. I had and have some, but they suck.
Suckily sucking the suck out of the suckerhood. Try that with a standard combo lock. I was able to break into many of them simply by feel. As to the safety of the lock: It depends not only on the number of different combinations, but also on how much time it taked to enter each. Propane is very expensive for home heating so it's worth the hassle of using our stove. After many years I have streamlined my methods for fire starting and the process was improved significantly when I picked up Fiskars baby axe, their 14" hatchet.
My old camp axe had gotten a wobbly head and no matter how much I tried I couldn't get that great of an edge on it. I picked up the smallest Fiskars at my local hardware shop. I use this small axe to chop kindling down into batons for easy lighting. I also use it to create wood shavings for starting my fires.
I try to avoid using paper as much as possible, preferring to break wood down so it lights quickly with just a match or two. The Fiskars 14" hatchet has a great angle for splitting small wood pieces, and is super sharp for making kindling of any size. It holds its edge very well and sharpens right up with a few angled strokes of a file or stone.
These hatches come with a lifetime warranty and it's clear they are made to last. These can be operated in low light conditions, when wearing gloves and also by people with poor eyesight. Resettable to your own directional code.
Please note that due to a highly complex mechanism this padlock would not be suitable for regular exposure to rain or water. We have had quite a few customers not follow the reset instructions correctly and end up locking themselves out of the padlock. If you are not technically minded please do ensure you ask someone to help you set the code in the first instance or attempt to set a very simple code first as a trial so you understand the procedure well.

Don't be fooled into thinking this is a novelty item by its innovative design. It is still a highly secure padlock using a 7mm hardened steel shackle, a solid 55mm body and anti-shim technology.
