Home made Abloy Classic key cutter/impressioning tool
Saw this at lockcon a couple weeks back. Home-made is somewhat understated, Jakko is a tool and die maker by trade and he made it on a CNC machine. But it's quite an amazing and simple little device. He gave a talk on impressioning Abloy classic locks, the implication was that he made this tool to assist with getting correct cuts on the key (with a properly prepared blank having milled slots where the spacers sit inside the lock).

The key goes into the right end, the small knurled knob pulls out so the mechanism can be rotated to one of 5 bitting positions/angles (you can see the hand-engraved numbers along the edge). A file is ran between the two small vertical rods (there's a second set out of sight on the bottom edge) which allows you to manually file the key down to the correct cut. The knurled knob on the left of the device turns one complete turn (with a ball-indent to stop) to move the key out for each disk position. The smaller part at the bottom of the case is a duplicate of the part already inside the device where the key is inserted (I was unsure why there were two, they appeared to be identical). Also there are horizontal hardened inserts not visible from this angle just below the surface where the file would cut into the body of the device when filing a key, presumably to extend the life of the housing. Very clever little machine.
