Re: Update 3 - the well-tempered blade

David Weaver
That's about as good of an outcome as you can hope for. I don't know if I've seen anything that cool take tempering colors, but if 340/350 on your thermometer corresponds to 390/400 due to issues bill mentioned with laser thermometers, it's still going to be good.

I don't think there's a lot of virtue in a 65 hardness first japanese plane. A few points softer (suppose it's still 61/62) and it'll be easier to sharpen and not lose that much edge life (maybe 20 percent). IF it loses a little edge life, is twice as easy to sharpen and doesn't chip, you'll be far ahead. It'll still make an ultra bright finish and you don't have to resort to back bevels now.
