Short version: the Tojiro DP santoku is the cheapest way to own a genuine VG10 santoku from a maker that publishes its numbers. It is the same proposition as the DP gyuto that has been the internet’s default first-Japanese-knife recommendation for a decade — a hard stainless core, a plain clad body, no decoration — rendered as a 170 mm flat-profile knife.
What you are actually buying
A VG10 core at about 60 HRC, welded between two layers of softer stainless, ground thin, and finished at roughly 15° per side. That is the entire specification and it is the specification that matters. VG10 at 60 HRC is the band where a Japanese knife stops being a novelty and becomes conspicuously better at cutting than a German one — the steel is hard enough to hold a much more acute edge without rolling, which is what makes the knife feel like it is falling through food rather than pressing into it.
The three-layer cladding is not cost-cutting. A hard core on its own is brittle; wrapping it in soft stainless adds toughness and corrosion resistance while leaving the cutting steel hard. When the same construction is done with a patterned jacket it is sold as Damascus at two or three times the price, with the cutting done by an identical core.
170 mm, and what the shape is for
A santoku is short, tall and flat. The edge has very little curve, so the whole blade meets the board at once on a straight downward push and a slice separates completely instead of hanging on by a hinge at one end. The blade is tall enough for a proper claw grip with knuckle clearance, and wide enough in the face to carry prep to the pan.
At 170 mm this is a genuinely nimble knife. It is easier to control than a 210 mm gyuto in a small kitchen or on a small board, and less intimidating for someone who has only used a supermarket knife. What it gives up is reach — a large cabbage or a watermelon is awkward — and the rocking motion, which a flat edge simply will not do. The full argument is in gyuto vs santoku.
The three things it does badly
- It is plain to the point of being drab.A stainless jacket with no pattern, a composite “eco-wood” handle, and a machine finish. If part of what you want from a knife is enjoying looking at it, this is not that knife and no amount of specification will change it.
- The handle is functional and no more. Symmetrical, hard-wearing, fine in a wet hand, and nothing like the pakkawood on a Shun or the shaped grip on a Miyabi. On a long prep session that is a real difference, and it is where most of the price gap goes.
- It punishes carelessness. At 60 HRC the edge chips rather than rolls. Bones, frozen food, ceramic plates in the sink and levering a stuck blade all take a piece out of it. That is true of every hard Japanese knife, but it is worth saying plainly to anyone stepping up from soft German steel.

Against the Victorinox santoku this is the whole hard-versus-soft argument in one category: the Tojiro holds an edge far longer and cuts more keenly, the Victorinox is cheaper, tougher and can be honed on a steel rod. Against the Shun Classic santokuthe cutting cores are near-equivalent and the gap is cladding, handle and finish — which the Tojiro vs Shun comparison takes apart in detail. Notably, Shun does not publish a hardness figure for its santoku, while Tojiro does for the whole DP line.
Living with it
Wipe it dry, keep it off the dishwasher rack, and give it a strop or a fine ceramic rod every few weeks instead of reaching for a steel one. It will want a real stone session once or twice a year, and a 1000/6000 combination stone does the whole job. The flat profile is a bonus on the stone — with no belly to sweep through, holding a consistent angle is markedly easier than on a curved chef’s knife.
Who should buy it
Buy the DP santoku if you want a real Japanese knife for the least money that involves no compromise on steel; if you already own a chef’s knife and want a nimbler second blade; if you push-cut rather than rock; or if you are buying your first hard-steel knife and would rather learn on something you will not mind marking.
Buy something else if you want a knife you enjoy looking at (Shun, Miyabi), if you will not maintain hard steel (a Victorinox or Mercer santoku and a rod), or if this is going to be the only knife in the kitchen — in which case buy the DP gyuto instead and get the reach and the tip.
How we reviewed this
We do not own this knife and have not cut with it. This review reads the specifications Tojiro and the retail listing publish — steel grade, line hardness, blade length, edge geometry, construction and handle — against the published figures for its rivals and the known behavior of VG10 at this hardness. Anything the maker does not state is marked Not published rather than estimated. Our methodology page sets out the whole approach.
