after a while you'll get used to holding onto a hot blade while grinding it. when i first started there were many times my hands would cramp and the blade would have to be pried from my hands, usually by my dad. he asked how i can hold onto a hot blade and keep doing it over and over again. i told him its knifemakers fever, kind of like buck fever. i did warn him the blade was hot so he wouldnt get burned. i have only been cut bad once from a knife i made. i now wear kevlar gloves so i dont get cut anymore if i have to work on a sharp knife that i dont want to dull down.
