The MAC Superior Series Santoku Knife is a thin, razor-sharp blade made of extra-hard high-carbon Molybdenum Vanadium alloy. This knife has a subzero tempered edge for excellent edge retention and rust and stain resistance. The raised strip on the blade puts small pockets of air between the knife and food, reducing drag. The Pakkawood handles are elevated for extra clearance and comfort. It is made in Japan with a 25-year warranty. 59-61 Rockwell hardness; 15° blade angle.
