Oneway's Vari-Grind 2 sharpening jig for using with the Wolverine base system.  Works for detail/spindle gouges and especially well suited for bowl gouges.  It is sometimes called a "school grinding jig" as it is a bit safer than the original Vari-Grind--in the sense that it is locked into the base and cannot be pulled away as was sometimes the case with the original VariGrind.
