This Tormek SVH-320 planer/joiner blade attachment in excellent cosmetic and functional condition. It's used for sharpening HSS planer or jointer knife blades of any length. Blades longer than 10-1/2"' can be relocated in the blade holder and ground in two steps. The minimum width of blade that can be used in this jig is 1/2". I used this for my 6'" joiner and my 15" planer blades maybe once or twice.
