Filing blocks for lock picks

These are just the ticket to drop in a chunk of broken hacksaw blade, then shape it with diamond files and sandpaper into a great lockpick! - Regular blocks can be clamped in multiple orientations or simply held in the hand

- Left & Right blocks have a 10mm x 10mm block on the bottom to register with the edge of a table or top of a vise if on it's side

- Vise blocks have a 20mm x 20mm block on the bottom so the block can be held in a vise and a secondary clamp or fingers can hold the material in the block for filing

Models are intended to be printed on end so that the layer lines help prevent the thin fingers from breaking under vigorous use. Mine are printed from cheap PLA at 50% cubic infill and work great for hand filing and light rotary tool work but will melt easily. Maybe I'll print some in a high temperature PolyAmide like PPA and see how much torture they can take! Save those fingers and prevent bending thin parts!
