While checking the diameter of a tenon I was turning with a wrench, it actually plowed the wood down to final size. That gave me this idea: Why not use sharpened wrenches as tenon cutters? So, I bought a set, ground the “cocked” side to about 30˚ and sharpened the tips. After rough-turning, I switch to the wrenches to complete the diameters and fnish them with sandpaper — wrenches will leave tenons a few thousandths oversize.
