Paul Sellers for a simple sharpening grip for a spokeshave blade.
It uses the spokeshave's own cap iron to hold the blade firm while it's being sharpened, and the length of the wooden grip gives me much more control and power than I can achieve with my fingers alone.
The body of this grip is an off-cut of laminated bamboo, but just about any wood would do. The little brass locating lugs are a pair of brass screws with the heads cut off. The cap iron screw is a 25mm pan-head No.10 screw with its point ground off. The front end of the grip is bevelled at 25°, leaving about a millimetre thickness in the front and with its heel rounded off. The but-end is rounded and bevelled for more comfort in the hand.
It only took about ten or fifteen minutes to make this little thing, and it's improved and eased spokeshave sharpening enormously.
