The SVS38 is for straight-shanked tools, such as wood chisels, carving gouges and tools for power carvers. Flanges ensure a 90° positioning of the tools towards the grindstone. Copes with tools down to 45mm (1¾") length and max width 38mm (1¼").
The jig has two parallel flanges running on both sides of the Universal Support. 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.
