The petty knife is the detail tool that serious cooks eventually reach for when a gyuto or santoku is simply too much blade. Kohetsu makes the AS Western petty in Seki City, Japan as a CKTG exclusive - the same Aogami Super core at HRC 64 and stainless cladding as the rest of the line, in a compact format built for in-hand trimming, peeling, and fine board work. The name Kohetsu loosely translates to "be happy." These knives are developed and specified by CKTG and available nowhere else.
At 120mm this petty knife features a thinner than average grind that lets the blade pass through food with minimal resistance - a quality that becomes immediately apparent on the first use. The 60/40 asymmetric grind works well for both right- and left-handed cooks. Stainless cladding over the Aogami Super core keeps the flanks protected and simplifies daily care while the carbon edge does the cutting work. The mahogany western handle with stainless bolster and three rivets is well executed - full tang construction, comfortable across grip styles, and finished to a standard that punches above the price point. Fit and finish are of a high standard throughout.
Care Instructions: Aogami Super is a reactive carbon steel - the stainless cladding protects the flanks but the exposed carbon edge will patina naturally with use. Wipe and dry the blade immediately after every use. Avoid leaving acidic foods on the edge. Hand wash only, never dishwasher. Apply camellia oil for long-term storage. Sharpen on quality water stones - AS at HRC 64 rewards good sharpening technique and responds beautifully to stropping.

Kohetsu AS Western Petty
Great Petty KnifePosted By: Brian - verified customer

My third Japanese knife and 1st AS steel. It is a razor. I have not needed to sharpen it at all in the two weeks I've used it. I just balsa and leather strop it every other use. Great for delicate garnish work, or even shallots and garlic. My western handled version had the rivets exposed a bit, so I gave it 4 stars. Everything else aside from that is 5 stars. Value is hard to beat. An AS steel knife for $100. Blade & cladding top notch.
