ATS-34 Steel: The Science Behind the Edge

By DRGSKL

Most kitchen knives claim 'premium steel.' Few can back it up. ATS-34 is different - and the chemistry explains exactly why.

Why Steel Grade Actually Matters

ATS-34 is a high-carbon, high-chromium martensitic stainless steel originally developed for industrial cutting tools. When Takefu Special Steel in Fukui, Japan began refining it for cutlery, it quickly became the benchmark for premium kitchen knife blades.

The Numbers That Matter

ATS-34 contains 1.05% Carbon, 14% Chromium, 0.5% Molybdenum, and 0.5% Manganese. The result is a steel that hardens to 60-62 HRC without becoming brittle - hard enough to hold a 15� per-side edge through heavy use, tough enough not to chip on a board.

The Bottom Line

The steel in your knife is the foundation of everything. ATS-34 is the reason DRGSKL carries a lifetime warranty. We built it to last.
