It is not without reason this jig is named "Multi Jig". It consists of a housing and two interchangeable seats for different types of tools, the open seat and the closed seat, which really makes it two jigs in one.

With SVS-50 you can sharpen square and skew turning chisels with straight or curved edges as well as parting tools, roughing gouges and gouges and chisels for woodcarving.
