Well i tested my sk5 trailmaster and am very pleased with it's performance! I tested it on water bottles,cardboard,hickory,oak,pine and bean cans. The edge did not chip or roll and the blade would still shave afterwards! Now i did not do a lot of chopping but i did enough to know that this is a very good knife with good heat treat.It also look's nothing like most of my Bowies as the blade is not very wide only about an inch and a half making it very easy to carry unlike most of my clumsy blades...but the spine is very thick @ 5/16" and the flat grind bites as deep as my much larger Bowies and it cuts with little effort! I do believe that i will finally be able to carry and use a prc knife without being ashamed of the stamp. I hope to see a Noss4 test on this knife!
