170mm Masakage Koishi AS Wa Santoku

Masakage Koishi knives are handmade with carbon steel clad with stainless steel. This is a great way to make a knife as you get all the performance of carbon steel (a very long lived edge, ease of sharpening and a silkiness when cutting) without most of the maintenance issues as cladding with stainless steel reduces the risk of rusting.

Masakage Koishi knives are hand-forged by renowned blacksmith Yoshimi Kato.

Kato-san visited District Cutlery in 2018 and performed a forging demonstration for our customers.
