Professional adjustable leather groover
This tool enables you to trace superficial grooves at a precise distance from the leather/hide edge.
Working distance from edge: from 0.2 mm to 35 mm
Provided also with a small "spoon" to create ornamental edges.
There is an illustrative video
The "Pro Stitching Groover Set", unlike most groovers, has got the blade on the axe of the handle, so that higher control and more effective pressure on the blade may be exerted on the blade.
The mandrel locks firmly the blade.
