The takobiki (蛸引き包丁) is a traditional single-bevel Japanese knife from the Kanto region, used for slicing sashimi. Despite the name — "octopus slicer" — it isn't built specifically for cutting octopus. It was developed for thin, clean cuts of fish and seafood, particularly the paper-thin usuzukuri style.
The blade is long, narrow, and squared off at the tip. That geometry rewards precise technique but leaves little margin for error: because the blade is so thin, a chip can compromise the whole edge. Traditional takobiki are mostly used by highly experienced chefs today; the sakimaru takobiki, a more forgiving variant, has become the more common choice in professional kitchens.
Takobiki to Sakimaru Takobiki
The takobiki developed as a regional alternative to the yanagi in Tokyo kitchens, where a squared tip suited precise slicing on the cutting board. Over time, the sakimaru takobiki emerged — combining the yanagi's curved, pointed tip with the takobiki's profile.
The sakimaru takobiki has a wider blade and a larger ura (concave grind on the back) than the traditional takobiki, which helps with food release and makes the knife more forgiving to use. That's largely why it has replaced the traditional takobiki in most professional settings.
Takobiki vs. Sakimaru Takobiki
Both are single-bevel sashimi slicers, but they differ in shape and how much they demand from the user:
Takobiki: Narrow, with a flat, squared tip and a small ura. Its thin geometry suits extremely fine slicing like usuzukuri, but it's unforgiving — a chip on the narrow edge is hard to recover from. It's now used mainly by experienced chefs or in specific regional traditions.
Sakimaru Takobiki: Wider, yanagi-like blade with a curved, pointed tip. The added width and larger ura improve balance and control, and the curved tip helps the blade release cleanly from the fish at the end of a slicing stroke.
Key Features of a Takobiki
- Blade Length: Typically 9 to 12 inches (240–300mm), long enough for a single clean slicing stroke.
- Blade Material: Traditionally high-carbon White or Blue Steel; also available in stainless options like VG-10.
- Edge Geometry: Single-bevel with a very fine edge — precise, but it takes skill to maintain and sharpen correctly.
- Backside Concave: Minimal ura on the traditional takobiki; more pronounced on the sakimaru takobiki, which aids food release and sharpening.
- Weight & Thickness: Light and thin, built for precision rather than force.
- Handle Options: Usually wa-style, for balance and control.
How to Use a Takobiki
Use long, smooth pulling strokes and let the edge do the work. Avoid pushing or sawing — both increase the risk of tearing the fish and chipping the blade. A traditional takobiki demands precise control given its thinness and squared tip; the sakimaru variation is more forgiving and better suited to daily kitchen use.
Care and Maintenance
- Hand wash only — never put it in the dishwasher.
- Dry it immediately after washing; don't leave it wet or soaking.
- Don't cut bones, frozen food, or hard-skinned produce with it — the edge is too fine for that.
- Sharpen with a whetstone; never use honing rods or pull-through sharpeners.
- Store it in a saya sheath or on a magnetic strip so the edge isn't knocking against other tools.
Yoshihiro Takobiki and Sakimaru Takobiki Knives
Our takobiki and sakimaru takobiki knives are hand-forged for the sashimi bar. If you're set up for usuzukuri-style precision, a traditional takobiki is the sharper-edged tool; for day-to-day sashimi prep, most chefs find the sakimaru takobiki more practical.
