I used a diamond rod to throw a quick touch up, I'll get a pick of my field sharpening kit when I get home. It consists of a brown rod from my sharp maker, that broke, a round ceramic white rod, and my diamond rod. This steel is heat treated very well in my opinion, it responds well to just a smooth ceramic. I haven't had to remove any steel yet, but next month when we kill our two pigs will be the ultimate test. We butcher the old Hispanic way, the way my grandpa taught us. We shave all the hair off of the pigs. We put gunny sacks over the pigs and pour hot water, then shave them down. From there we split the fat down in sections, which is really rough on an edge. Not sure if you guys know what chicarrons are, but that's a Mexican delicacy. I'll have to get some pics, it's hard to explain. Better to see.
