I have a set of angle gauges I got given by a mate that was no longer in that trade - same guy that gave me the Sandvik carbide gear. That helps. Hardest part is the tool's nose radius...

Unless it's large I never grind the nose radius, Form it with an oilstone by hand by sliding the stone around the radius.
