I forget that brand of lock, it's on my toolbox at work. It's easy to work on, just lock it into the vise and tap away. The gravers are allen wrenches that I modify: heat them up, straighten out the bend, then I use a die grinder with a sanding disk on it and grind a square on the end, cut a 45 degree angle on it. I heat it up to a bright red and quench in motor oil, then use a wetstone and sharpen it up and there's an engraver.
I find a virtual ton of allen wrenches on the washfloor at work, pick up about 5 a day and what else does one do with free stuff besides using them as allen wrenches? Make stuff out of them....the make great tiny little chissels too.
Maybe I should do a step-by-step process on how make them.....who knows.
