I was curious if anyone has the Henry Taylor 3/8 x 3/8 round nose scraper or the spear point. What your thought were on these. I ground my own, 1/4" thick, from a couple of cheap tools for the time being. I was thinking of grinding my own from the Thompson tools if I do not find one I like. I would prefer 5/16" thickness or better. Any wisdom from the " worldly spinny gurus" would be appreciated. Thanks for your time.
