Ever wonder what makes one kitchen knife razor-sharp for months, while another turns dull after slicing two tomatoes? A big part of the answer lies in the type of steel used to forge the blade.
At Cooking Guild, each knife series uses premium steel carefully chosen for sharpness, durability, edge retention, and—of course—how it feels in your hand.
Let’s walk through the main steel types used across our collections so you can choose the right knife for your kitchen needs (and know what makes it great).
1. San Mai Steel — Strength, Flexibility, and Japanese Heritage
What it is:
San Mai means "three layers" in Japanese. It sandwiches a hard, high-carbon core (like Hitachi SLD or AUS-10) between two softer stainless steel layers. You get the sharpness of high-carbon steel plus corrosion resistance and flexibility.
Why it’s great:
It offers superior edge retention without making the blade brittle. That means fewer chips, longer use, and a beautifully balanced knife.
Where to find it:
-
Kaiju 8” Chef’s Knife – Made with Hitachi SLD tool steel core and 420 stainless outer. A powerhouse all-rounder for serious cooks.
-
Kaiju 7” Bunka Knife – For precise slicing and detailed prep, also forged with San Mai.
-
Dynasty Series Santoku – Forged with an AUS-10 core and 430 stainless steel for durability and control.

2. Damascus Steel — Beauty Meets Performance
What it is:
Damascus steel is made by folding multiple layers of steel—often 67+ layers—to create a wavy, eye-catching pattern. It’s not just about the looks though. This process increases toughness and allows for a razor-sharp edge.
Why it’s great:
It’s strong, holds an edge like a champ, and looks like a work of art. Perfect if you want a high-performance knife that’s just as beautiful as it is functional.
Where to find it:
-

3. AUS-8 Stainless Steel — Tough, Dependable, Versatile
What it is:
AUS-8 is a high-carbon stainless steel from Japan known for being incredibly tough, easy to sharpen, and resistant to corrosion. It’s a favorite among chefs who need reliability in a busy kitchen.
Why it’s great:
It gives you solid sharpness, without being so hard that it chips or is difficult to maintain.
Where to find it:

Kaiju Hybrid Cleaver – Half slicing blade, half chopper, all forged from AUS-8 steel. Great for transitioning between thick and thin cuts.
