CPM 10V is a steel made from powdered metal (CPM=cucible partical metal) with a high content of vanadiun. Its claim to fame is combining toughness and abrasion resistance. I can see this being a great blade for a chisel where you need the toughness, but I wonder if it’s cost effective for a plane blade. I don’t know from personal experience as I have never tried this product, but I speak from knowledge of metals and casting which is a field in which I have worked for 40 years.

In general, powdered metal products allow the manufacturer to combine metals that normally could not be combined in the molten state. Kinda like being able to mix oil and water. You can mix a metal that normally has extreme hardness but is brittle as glass with a metal that is extremely tough, but not very hard and come up with a material that has both properties.
