I just bought 2 8OT's (the last 2 from Wal-Mart) and will give them as presents. I read in a previous post that Schrade had switched these over to stainless. Both knives are clampacked and say high carbon steel. There is no Schrade + stamped on the main blade either. Is it fair to say that these are carbon blades. I'd rather not open them to give the lemon test. Any input?
