This might sound like a stupid question for most here but its the thing that is giving me the most trouble. After sanding the scales to the tang how do you go about shaping your handles. I like a half round contour as opposed to a flat handle so I tend to contour up to the top and bottom of the tang. I usually have go back with the disc or my recently purchased spindle sander to flatten it back out. How do you keep the tang flat and still get a good contour?
