Tojiro R2/SG2 Petty

by Tojiro


This is a utility knife designed to be used for various purposes. As an upgrade from their popular DP series, this Petty knife 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 enables 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.

    Great Knife - my first purchase of a high quality Japanese knife

    I recently purchased a Tojiro R2/SG2 Petty knife, (150mm version) from the Burrfection store that has been out of stock for months. The folks at Burrfection sent me an email update reminder as soon as the item was available again. I ordered the knife and it arrived to my destination in the United States a few days later without incident. I was not able to purchase this specific knife model through any vendor in the United States. I've had a chance to use thus knife for about days days now, and it is the sharpest knife that I have every used out of the box, and I have many specialty knives as a comparison. First time using the Burrfection store, and this brand of knife, and would recommend to others.

    This knife is amazing!

    I've been wanting a petty knife for a little while and my husband ended up getting me one for my birthday. I really enjoy cooking and we have many really good knives, but nothing compares to this one. Not only does it do an amazing job of cutting, it's light, precise and a really beautiful knife. Highly recommended!
