These are very interesting knives, and a good fit would be in a commercial kitchen. The steel is like a tougher version of SG2. It still takes that razor sharp edge, but it's tougher and less 'chippy' than SG2/R2 even at higher HRC ratings.

Only certain makers are allowed to use this steel. It's exceptional. Grinds on these are a bit on the workhorse end of the spectrum. The steel has the ability to take and hold an extremely sharp edge for an extremely long time. I have chefs who have had their knives for months, and have kept the edge "like new" with stropping alone. SG2 / R2 is an excellent knife steel, but this just does it all better.
