I'm fairly new at this, so I'm sure this is a real newbie question. The first knife I made using 1084 that turned out decent enough to stay out of the scrap bin, I just found that it is developing small chips out of edge when I used my small hand sharpener that has the coarse,fine and ceamic rods. When I sharpened the first time I used whet stones so I didn't have this problem, and got very good edge. Being as I haven't been at this long, I use a homemade charcoal forge I built from an old BBQ which I rigged a 1/2" steel pipe with small holes and made a fitting to connect my air compressor too. I heat them to non magnetism, and quench in canola oil. Then I use an old toaster oven with thermometer and temper to 450° for an hour, air cool and again for 3 times total. It has worked out perfectly for the other few I've made, but for some reason not this one. My question is after grinding these chips out, should I be heat treating again? Then for tempering should I go a little hotter? Like I said kinda newbie question, but from the short time since I've joined this forum, and reading just some of the knowledge here I'm sure I can the right answer. Thanks for everybody's time reading.
