RETRO SERIES · BUNKA

A k-tip built for tip work and push cuts

The bunka is the Japanese all-rounder for cooks who want one knife that does tip detail and flat push-cutting. The Retro Series 8.5" runs a reverse-tanto k-tip for scoring, slicing and fine point work, then a long flat edge for clean push cuts through onions, herbs and boneless cuts. The frosted black stonewash gives it the vintage look the series is named for, while the spec underneath is straight working steel.

WHY A BUNKA

Tip precision and a flat edge in one knife

The k-tip sits low and sharp, so the point lands exactly where you put it for scoring, fine slicing and detail work. Behind it, a long flat edge favours push cuts over rock-chopping, keeping board contact even and slices consistent. At 186g with a 215mm blade, it has enough presence to move through dense veg without feeling heavy in the hand.

BLADE

10Cr15CoMoV core, 3-layer composite Damascus

The cutting core is 10Cr15CoMoV, vacuum heat treated to 60±2 HRC for a balance of edge retention and easy resharpening. It is clad in two outer layers of SuS410 stainless that carry the Damascus pattern, giving a 3-layer composite blade. The edge is ground to 15° per side (30° inclusive) and the spine measures roughly 2.4mm, thin enough to fall through food cleanly.

IN HAND

Octagonal wa handle, red wood and buffalo horn

The handle is a traditional Japanese octagonal (wa) shape in red wood with a black buffalo horn ferrule, set on a full tang for a solid, balanced feel. The faceted profile locks into a pinch grip without rolling, which suits the controlled push-cutting and tip work a bunka is made for. Hand wash and dry only, never the dishwasher.
