I have a John Lloyd Custom slipjoint that I use the heck out of , its been dropped , banged around and used to cut all kinds of steel. Though the blade steel is 52100 so it's not a wonder steel , but that blade obviously wasn't told that because it cuts like crazy.
I bought a few , couldn't see myself using them , so they were soon sold.
After a few years being into knives , I determined I would only buy with the true intent to use. I don't torture my knives , but I sure don't worry about scratches , scuffs , nicks and dings.
I have used my Elishewitz , Striders and Rinaldi's to cut stuff I shouldn't , like drywall , shingles , tar paper and steel banding from server crates , but that is what I had when I needed to get something done. I look at my knives as history , I see the character marks and remember how they got there.
