Very similar alloy composition to M390PM coming out in Benchmade ( silbert) and Kershaw ( Volt) in the near future.
The steel is great, and the knife came sharp, and is a wicked penetrator. The tip is like a needle. The only problem I had with the knife was the grip. It was very uncomfortable for me. In any hard use situation I could see actually getting scraped and or bruised by the grip. It goes way beyong what I call a "hot spot" on a knife grip.
It's a shame too as the steel , grinds and blade shape are top notch. It was the first production knife I know of in 20CV. Up until the SOG's release it was only available in Hinderers, and some Greg Lightfoot customs.
