Knives A8 Mod Steel

Knives with A8 Mod Steel. A8 Mod steel is a modified version of the American A8 class tool steel. The original A8 steel was designed for applications where high toughness (resistance to cracking and breaking) and wear resistance (edge retention) are key.

The "Mod" (Modified) addition signifies that the manufacturer slightly adjusted the chemical composition (often by increasing carbon, chromium, or molybdenum content) to improve cutting performance without sacrificing the main advantage, which is toughness. It is popular for larger fixed-blade knives that are meant to withstand heavy use.
