This patented jig was developed for short woodcarving tools, butt chisels and tools for power carvers. The jig has two parallel flanges running on both sides of the Universal Support. Max tool width 1-1/4''. The technique achieved with this design ensures that at all times the jig – even when rotated – holds the tool square to the grindstone. This is a great advantage, as you can continuously concentrate on how the edge touches the grindstone or the honing wheel without having to worry whether the jig is square to the stone.
