I answered your PM over on BF as well, but yeah the Regulator is definitely SR-101.... which is AWESOME!

With the differential temper, it's tougher than you'll ever need, and the edge will last a long time.


Ask anyone which knife they would rather have - a Camp Tramp or a SoD. Most will answer Camp Tramp. They are essentially an identical knife, except the CT has a round choil and SR-101. It's a great, great steel, especially when given a differential temper to up the toughness without sacrificing edge holding.
