This groover has the groover blade centred under the handle and the metal guide is released, adjusted and tightened with a metal chuck.
This gives more control and a downward pressure directly on to the grooved line.
It can also be used as a freehand groover for carving out design and relief work.
Included is a small modelling spoon for decorative borders and smoothing.
The width adjusts from 2 to 33mm (1/16" to 1 5/16").
