5.8" Bunka Knife - Retro Series (PM8S)

Reach for this when you want the bunka profile in a size that suits lighter work. At 5.8 inches, it handles the mid-tier prep jobs - slicing mushrooms, dicing a small block of firm tofu, prepping a single fennel bulb - without the weight and reach of the larger bunka. The reverse-tanto tip punches through the surface cleanly, and the flat belly keeps full board contact on every push cut.

A Petite Bunka for Precise Work

The petite size isn't just a scaled-down version of the longer knife. At this length it works better for in-close tasks where you want to feel exactly what the blade is doing. Thin-slicing a raw fish fillet, halving a block of mozzarella, or running through a punnet of mushrooms quickly are all jobs where this size outperforms a longer, heavier blade. It's also a good match for a smaller cutting board or a compact kitchen where a full 8-inch knife feels unwieldy.

Same Steel, Same Handle as the Rest of the Series

The blade is 3-layer 10Cr15CoMoV composite - hard core with corrosion-resistant outer layers - vacuum heat-treated to 60±2 HRC. It holds a very fine edge and responds well to a strop when you want it back to shaving sharp. The octagonal Red Wood handle with genuine black buffalo horn collar is the same profile as every other Retro Series knife, so the grip is already familiar if you've used a larger piece in the collection.
