Once the analyses were complete, one metal emerged as the clear winner: PM-V11.
The PM-V11 alloy was the most durable metal tested on the impact test, and finished a close second on our wear testing. Of critical importance to us (and to you) is that blades made from the PM-V11 alloy can be sharpened with common abrasive media such as water stones. It takes a bit longer than O1, but PM-V11 blades sharpen slightly faster than A2.
About the PM-V11 Alloy and Powdered Metals
PM-V11 is a powdered metal (PM) alloy. To form a PM alloy, constituent metals are melted and mixed together, then atomized, creating very small particles that cool and harden, forming a powder. This powder is screened to ensure consistent particle size, and then heated under pressure to form a billet. The billet is then rolled to the required thickness, ready to process as a conventionally smelted steel would be. The PM process yields a steel with a very fine grain structure that is uniform throughout.
So how do PM-V11 Blades Perform?
When we gave test blades to a group of woodworkers, the feedback was uniformly positive (bordering on ecstatic in some cases). They reported that in day-to-day use PM-V11 blades readily sharpened to a keen edge that cut cleanly and remained sharp for much longer than O1 or A2 steel blades. They didn’t need a scanning electron microscope or an advanced degree in metallurgy to know this was simply a better blade material.
