What is PM-V11-Steel?
After more than two years of research and testing, VERITAS introduced plane blades produced from PM-V11, a new steel alloy. The PM refers to a process known as powder metallurgy, whereby molten metals are atomized into small particles, which cool and harden into a fine powder that is then heated under pressure to form an ingot. To make PM-V11, a unique mixture of metals combined into a proprietary alloy yields a steel with a very fine, uniform grain structure that is inherently more durable than that of steels produced using ordinary manufacturing processes.
Blades made from PM-VI1 are highly resistant to dulling or damage from wear and impact, yet are as easy to sharpen as A2 tool steel. PM-V11 blades can take a keen edge and hold it through extended use; once dulled, the edge can be quickly returned to a sharp condition using water stones or other common sharpening methods. The testing shows that a PM-V11 blade edge lasts at least twice as long in use as an A2 blade before it needs sharpening - a significant improvement over common blade steels in use today.
Though most of our Japanese waterstones work well with powder metallurgy steel blades we at fine-tools.com recommend to sharpen powder metallurgy steel blades on Shapton stones.
