I was lighting a fire this week and used a nessmuk to create fuzz sticks and baton finger size sticks off a log for kindling. the muk did great at all of this but when I got done I noticed the blade was damaged in 4 or more spots. it will still shave. it is that sharp but the blade edge is bent. batoning wasn't an issue but twisting the blade to finish the split or break off a curly Q caused the edge to bend.
the swamp rat, scrap yard, ranger, coldsteel, and even china made knives I use handle this just fine. I was very disapointed with the 100 dollar little nessie. I am still waiting on the scrapmuk to arrive and don't believe it would be so fragile. when it comes it will be my go to bushcraft knife.
