S7 Shock Steel Tool Steel
S7 Shock Steel is an extremely tough tool steel designed for applications where conventional materials fail. Thanks to its exceptional ability to withstand impact and high mechanical stress, it is among the best tool steels available. In this category, you will find products that take full advantage of this steel – from work knives and axes to high-end katanas and wakizashis designed for effective cutting of tatami mats.
What is S7 Shock Steel and why should you choose it?
Extreme toughness and impact resistance: S7 is a typical shock-resistant steel that can withstand extreme blows without cracking or deforming. Ideal for harsh conditions where ordinary blades fail.
Ideal for cutting disciplines: Thanks to its structure and heat treatment, S7 is the best choice for katanas and wakizashis designed for cutting mats. The combination of hardness and flexibility allows for deep, clean cuts without damaging the blade.
How it is made: S7 steel is melted in electric furnaces, alloyed with elements such as chromium, molybdenum and vanadium, and then rolled, annealed and precisely hardened. Hardening takes place in air at ~1000 °C and is followed by double tempering. The result is a strong yet flexible steel with a hardness of up to 58 HRC and exceptional mechanical resistance.
Who do we recommend S7 steel products for?
✔ Samurai enthusiasts and tameshigiri practitioners – who are looking for a katana that can cut through mats without fear of breaking or bending.
✔ Outdoor and survival users – for whom blade reliability is a matter of trust and safety in the field.
✔ Craftsmen and professionals – who need tools that can withstand hard work and long-term use.
