Review on BONATE Precision Blocks 0.0002 Hardened by Durioki Cordaro

90 degree angle, quick straight lines, quick measurement. Tool radius pencil in a hole, turn the pencil in the radius of the hole of the circle you need, the weight of the paper. They sit on my desk all day and are used often. In most cases, my square and ruler have been replaced. Blade alignment and fence spacing are magic!
