There are made on a 3D printer and are unique to us.

Starting top left:

A V-shaped jig for gouges

A jig for shorter or stubby chisels

Two wedge shapes for skew chisels

Second row there are 4 drill guides. The smaller the drill the higher the angle, the harder the material the shallower the angle

All have a tip angle of 59º which equates to half of the normal 118º for std drills

The 7º one is mainly for large drills

The 9º, 11º and 14º are for smaller drills
