This is a router template to make handle cut outs on cutting boards. This template can be affixed to the work piece using double sided tape or clamps. In order to use this template you need router template bits (link below).
This template makes a handle that is 3" wide and 5/8" tall. Depth of the cut out is dependent on the bit used. The handle on the cutting board in the picture was made with a 20mm long template bit.
The author marked this model as their own original creation.
