The Scrapper Six was designed as a combat/utiliy knife. It is also useful as a camping or hunting knife.
You will come to love its fast handling and perfect balance in the hand.
Unless you do a lot of batoning the blade to split wood, the coating should hold up well. If it wears, get some flat black epoxy paint and recoat it.
Sharpen as you would any other knife. SR77 is easy to sharpen. Any good quality stone will work fine.
Enjoy it, knowing that it is one of the very toughest knives ever made.
