I have used sebenzas in all blade steels. ATS34, BG42, S30V, S35VN, even Devin Thomas's SS Damascus. They ALL Cut well, Held an edge, Is easy to sharpen, Is easy to maintain, VERY corrosion & stain resistant. I have the most experience with S30V as thats whats mostly on the Regular Sebenzas that I prefer. But, I have had several sebenzas over the years with the other blade steels and Honestly, have had no issues with any of them. I sharpen them all the same. I just never see a ton of difference between any of them, if any difference at all. My sebenzas get USED as well. I have made literally TONS of posts over the years here showing my sebenzas in action cutting everything from food, to wood, to tons of cardboard, to tar paper and shingles. I have never had any of the blade steel Roll, Chip, Bend....Nothing.
My motto over the years and with the Tons of experience I have had with CRK is that if its " Good enough for Chris Reeve, its definitely good enough for me ".
