Titanium Blade Introduction

Titanium (typically utilized as an alloy such as Ti-6Al-4V) is a specialized, non-ferrous blade material celebrated for total corrosion immunity against saltwater, an outstanding strength-to-weight ratio, and non-magnetic properties. It exhibits remarkable structural ductility and fracture toughness without the risk of rusting. However, unlike traditional cutlery steels, titanium suffers from low base hardness and an inherent lack of wear-resistant carbides, resulting in inferior edge retention. The cutting apex dulls rapidly under abrasive contact unless surface-carbidized, making it ideal for specialized dive utility rather than sustained slicing tasks.
