I just recieved my new 15 Angkola and Im quite pleased with it. Being new to Kukuri knives there are a few questions I have. I went out into the woods today and put my new blade to work. I found it chops extremely well but when I placed a loop of nylon cord over the blade,no amount of effort could get the cord cut. Here are my questions 1 My AK15 is relatively dull is this normal?2How sharp do most of you make your kukuris and whats the best way to do this? 3 Isnt a razor sharp convex edge backed by a half inch of steel better than a thick strong but dull edge? Thanks in advance Hannibal
