Ikeuchi Sakimaru-Gyuto combines the blacksmith’s familiar design language we’ve come to know and love and our completely reimagined, contemporary blade shape. The blade’s unfinished (kuro-uchi) layer was hammered until what came out was an intricate tsuchime finish, dotted with miniscule hammer dents. With a beautiful sand-blasted kasumi line separating it from the cutting edge, it is a real rustic masterpiece.

Knife obsession is a very real thing. It's a good kind of obsession. The kind that results in ideas popping up when you’re brewing your first morning coffee and that motivates you to keep discovering, to keep widening your horizons.

It was one of these idle moments when an idea popped into Luka’s* head. Single bevel knives. The specificity of their tasks is what scares a lot of users from using single bevel knives, believing they are too advanced for them.

This kind of geometry enables a half-size, much sharper angle, and consequently higher sharpness of the knife, which cuts more cleanly than double bevel knives. The main advantage in terms of function is that the blade pushes the slice of food that is being cut off away from the blade, causing it to fall away from the knife. The flat edge on the opposite side (uraoshi side) has a slight concave grind to it, which breaks the surface tension between the knife and the food. This allows the flat side of the knife to glide against the food with much less resistance.

While this knife may not be the star player of the food prep team, it is however the perfect love-child of the single-bevel knife shapes. Its wide profile, similar to that of an usuba or a deba, gives it all the makings of a chef's go-to knife for precise and complex techniques, like the julienne or the Japanese katsuramuki. Despite the age-old saying, (in the kitchen) size does in fact matter, and the knives listed above usually lack it. This is where the lengthy gyuto really shines - the 220 millimeter blade is perfect for longer, precise pulling motions used when slicing meat and filleting fish too.

To sum up: by joining a universal shape with a single bevel grind (giving the knife the width of a gyuto, with all the perks of a chisel ground knife) we managed to get the best of both worlds. Intrigued?

This sakimaru style single bevel gyuto is exclusive to SharpEdge and was created in collaboration with Ikeuchi Hamono.

This gyuto differs from others of its kind by two very distinct characteristics. The first one is the aforementioned grind of the blade, and the second is the blade’s unusual shape. The spine is straight and the belly tapers in a continuous curve, until making a sharp turn right before the point. This is where the name sakimaru comes from, it refers to the tanto tip.

The single bevel blade is suitable 🚨 for right-handed users only!

The blade was forged by the Ikeuchi Hamono smithy. Its construction is called ni-mai, meaning it’s composed of a hard cutting edge (hagane) and a softer, external layer (jigane). The hard core is made out of Shirogami #1 steel and the surface of the jigane layer is rocking a special hammered (tsuchime) kuro-uchi look (for more take a look at our Blade construction: Blade Finish article).

Advantages of Shirogami #1 steel are a very fine, gentle sharpness - it is easy to sharpen, and remains sharp for a long time. The high carbon steel will develop some patina after time, so we recommend oiling the blade regularly. Learn more about knife maintenance here.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.


Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

→ For in-depth information about patina, read our dedicated post on patina.


Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
