Questions & Answers
What are the differences between the Zwilling and Shun versions of Bob Kramer's Santoku knives?
The Bob Kramer Shun knife is consists of a 3mm steel blade that is composed of an SG2 core (64-66HRC) clad with true pattern-welded nickel and Damascus stainless steel for a beautiful, razor-sharp and lasting edge.
The Bob Kramer Carbon Steel knife is formulated from a type of straight carbon steel called 52100 —the exact type used by Bob in his own shop —and heat-treated to a hardness of 61 Rockwell. That means this knife has the ability to take an extremely sharp edge, to hold that edge under all sorts of use and abuse, and remain easy to sharpen. The full tang of the blade is tapered to Bob’s precise specifications, and the blade is sharpened to 15° on each side of the 50/50 edge with the traditional three-step hand-honed edge.
The Carbon Steel is susceptible to oxidation, which means it needs to be hand washed and completely dried after every use to avoid rust. It will also develop a discoloration after time. This is known as patina and is actually a desired effect for the carbon steel blade as it not only protects the blade, but it creates a one of a kind heirloon piece.
