The Kohetsu HAP40 Wa Petty 180mm is a mid-sized petty which can do service as a perfect all-around utensil for chefs of all kinds. It’s small enough for the most intricate work, like garnishes and handheld peeling jobs, yet large enough for more general cutting and slicing duties.
The slim and light blade measures just slightly under the advertised 180mm with a nice height of 29mm. It has a nicely shaped tip and a gently rounded belly forward of the main cutting area. While it is on the thin side of petty blades it is certainly no laser. This fine utensil features a progressive grind and is finished with an asymmetrical 50/50 bevel.
HAP40 steel is manufactured by Hitachi Metals and the robust core semi stainless steel is then clad in a full stainless alloy for added protection and strength. The exposed HAP40 edge will eventually take on a nice patina. For lovers of traditional Japanese knives, we have specified this item with a lovely upgraded black and grey pakkawood octagonal handle.
