aero,
Ya I layed out the 3 groves at roughly 120 dgrees and started them with the edge of a file, then split those with a razor blade. The I dry-fit the flakes for size. Next slopped on some pitch and set the flakes by forcing them into the slits, I formed the cutting point by haveing one flake protrude past the tip. Then I used a lighter to "slick down" the pitch and hafted the shaft right behind the head. I think you could run them farther up the shaft if ya wanted to.
