That is a rather intersting hobby. It would be handy to know somebody like you if I ever locked myself out of my house.
BUT! Can you pick this?
I am a new picker and can only open some locks. I could not open the lock you are showing, I do know that model. It seems very clever and perhaps it is but it has been picked by several people. A very beautiful lock is the Forever Lock. Such an elegant and functional design.
It claims to be unpickable and I can see why the designer would have believed that at it's invention. In picking a lock you need to be able to manipulate the locking mechanism - that is lock picking. In the Forever Lock, the locking mechanism is never visible or reachable, so this lock would seem un-pickable.
The fellow who did pick it, did it in less than fifteen minutes.
There always seems to be a weakness in whatever locking system is created. If it can be opened, then can it be opened in another way?
There are some great lockpickers out there. They transcend, they are artists. There are however several locks that have never been picked and no one is claiming they have. This actually makes lockpickers very happy. We are not glad that a lock is pickable. We have a lot of fun finding out how it can be picked but I think for most pickers, the greatest joy is finding a really good lock. There are several.
For around $100 USD the ABUS Granit is really something and it has a largest cousin that weighs more than 3lbs. So far as I know, no one has ever picked one. Isn't that great? Something that really will protect you.
For aspie obsession and fun you can look at the
Sargent and Greenleaf US Model 951. It costs more than $2,000 and isn't meant for personal use though if you have the funds ..
Besides having a Medico core, which is nearly un-pickable it's housing (which is what you really pay for) is through hardened, case hardened and impregnated with ceramic so that even a grinder can't get through it. A heavy rifle shot won't leave a mark on it. Shooting at it all day won't leave a mark. So find the key or find a welder ;-)
