Kohetsu is a CKTG exclusive line made by Tsukahara in Seki City, Japan — one of the country most respected knife-making regions — and the 1K6 line represents an accessible entry point into serious Japanese knife performance. The 1K6 stainless steel alloy is hardened to 60 HRC, offering a strong balance of sharpness, edge retention, and stain resistance that makes it a practical choice for cooks who want high performance without the maintenance demands of carbon steel. The burnt oak octagonal handle gives the knife a distinctive character that bridges traditional Japanese aesthetics with an everyday working tool.
This cleaver is roll-forged from mono steel — a single piece of 1K6 stainless throughout — which keeps the construction clean, the balance honest, and the weight predictable in hand. At 210mm with an impressive 81.5mm blade height it has real authority on the cutting board. The tall flat blade is ideal for the push-cutting style favored by Chinese and Japanese cooks, excelling at vegetables, proteins, and general prep work. At 290g it is substantial but not heavy — enough mass to work efficiently without fatiguing the wrist through extended sessions. A note worth knowing: our cleaver saya does fit this knife but sits on the loose side.
Care Instructions:
1K6 stainless steel is low maintenance and rust resistant with proper care. Hand wash and dry thoroughly after use. Avoid the dishwasher and hard surfaces like ceramic boards. Sharpen on quality water stones and strop regularly to maintain the edge.
