Can anyone comment on the quality of Al Mar's products. I'm kinda new to knives and just bought an Al Mar SERE 2000 with S30V steel and a D2 Ka-Bar. I'm just making sure I haven't got ripped off! How good is S30V and/or D2 steel compared to 1095, vg-10, aus8, etc.? What is the ultimate steel used in knifes?
