The Yu Kurosaki HAP40 Gekko Petty Knife 150mm is a high-quality Japanese kitchen knife, expertly handcrafted by blacksmith Yu Kurosaki in Echizen, Japan. Designed for precision, this knife features a core of HAP40 steel, known for its outstanding edge retention, making it ideal for prolonged use with minimal sharpening.
This batch of Gekko series knives will be the last to feature HAP40 steel, as Kurosaki transitions to VG-XEOS for future releases.
