Z-Wear PM Information & Composition

I am a big fan of Crucible CPM3V. It is my favorite blade steel. However, Z-Wear looks like it might replace 3V. I will know more after testing.

The Z-Wear datasheet says it has more toughness and edge holding than 3V. The composition is similar to 3V. It has the same amount of chromium, close to the same amounts of molybdenum and vanadium. It has more carbon and 1% tungsten which 3V does not have. I'm looking forward to testing this steel.

This high carbon alloy steel is extremely tough and has enough chromium to have some corrosion resistance. Grind the edge thinner than normal. The steel is tough enough to support a thin edge.

Update: ABS Mastersmith Russ Andrews told me Z-Wear is the same composition as discontinued Vasco Wear. This steel has an excellent reputation for edge holding.

CPM3V, CTSPD1, CruWear, Vanadis 4 Extra and Vasco Wear are shown in the table above for comparison purposes.
