Ultra-Hard Japanese Steel Knives (ZDP189/HAP40/SGII)

This collection brings together our three hardest modern Japanese steels: ZDP-189, HAP40 and SG-II (R2). All three are made by powder metallurgy, which produces a fine, even grain that can be hardened far beyond conventional knife steels. The result is exceptional edge retention.

ZDP-189 offers the most extreme hardness, HAP40 balances hardness with toughness, and SG2 is a fully stainless all-rounder. Choose from gyuto, kiritsuke, petty, nakiri, sujihiki and more. To protect these hard edges, sharpen them on quality whetstones and use wooden or soft synthetic cutting boards.
