If you don't machine, or are already way advanced past me, you can skip this.
I have read lots of stuff about how to grind cutting tools for lathes, and I have never quite managed to produce a particularly useful tool from an HSS blank, or even successfully reshaped an existing HSS cutting tool. This video by This Old Tony does a spe4ctacular job of explaining why each grinding operation is needed. I fancy that I now can do this.
Even if you are not terribly interested in machining, This Old Tony is riotously funny.
