Resistant to rust, this low maintenance steel is perfect for long term display. It is not suitable for functional use in swords due to inherent brittleness.
Stainless steel has high levels of chromium to give it impressive resistance to rust and blemishing. This steel requires very little maintenance and is ideal for display swords. While often eminently suitable for knives, the high levels of chromium make a sword blade brittle and prone to damage or breakage when dealing with the high impact resistances that swords are subjected to. Thus stainless steel is unfit for a functional sword blade.
