Went to work with my M43 today limbing a pine tree that had fallen not too long ago. The wood was still green and at first the M43 was making short work of it, then the unthinkable...I looked down and there was a fairly large dent/roll in the blade about 4 inches up from the handle. At no time did the blade of that kuhk ever come into contact with anything other than pine tree. No rocks, no metal, no dirt. I continued to work with the knife as it was my only means of limbing the tree and I didn't want to drive all the way back home to get something else. By the end of the day my Kuhk looked like it had serrations! there are roughly six good sized dent/rolls starting from the first and continuing on up the blade nearly to the tip. I know that this thread is worthless without pics however my girlfriend has my camera with her so I won't be able to post pics till tmw but I will, I'm not one to come on here and make claims and not back them up:thumbup: I figure its just a bad heat treat but the problem is I have used this kuhk several times before with no problems at all...anyway just thought I would share this with you all.
