Tojiro R2/SG2 170mm Santoku

by Tojiro


As an upgrade from their popular DP series, this Santoku is made of high carbon, high alloy R2/SG2 steel core, heat-treated to 63 HRC, and clad with 13-chrome stainless steel. The harder steel allows the blade to hold its sharpness for longer and the thinner behind-edge ensures a sleek cutting performance. Overall, an excellent value for money choice for those who are looking for a step up from Tojiro’s popular DP series.

    Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

    Cutting Surface:

    Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


    We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
