My father did a workman like job of sharpening a knife. Decent edge but nothing to brag about. About the age of 12 I got interested in learning how to sharpen a knife and he showed me, but cautioned me to match the edge to the job. That is that not every job requires a razors edge and sharpening to that level removes a lot of metal if you get carried away like kids do. Yeah, yeah, yeah I thought. I proceeded to sharpen to a razors edge every blade I came across. I found that type edge while extremely sharp did not last for heavy rough use and was prone to nicks. Low and behold I found his workmans like edge stood up to heavy use. I do reserve one blade on multiple bladed knives for that razors edge but it rarely gets used. Funny how much smarter our parents get as we get older.
