CPM® MagnaCut™ is a remarkable powder metallurgy steel conceived by Larrin Thomas, a Ph.D. in Metallurgical and Materials Engineering. MagnaCut challenges traditional stainless steel chemistry by reducing the amount of chromium in the steel to a precise range while adding vanadium and niobium. The result is a blade material that offers an extraordinary balance of wear resistance, toughness, and corrosion resistance.

In this post on the Spyderco.com forum, from 28 January 2022, Sal Glesser reflects on his experiences in the search for the best performing corrosion resistant steel: Interesting to watch the development march forward in time. Just "Talkin Story", Gail and I began the search for a corrosion resistant edge back in the early '80's. Being sailors and divers we could clearly see the need. 440C was the best at the time and we felt better could be found. We tested a lot of materials; Titanium, Ceramic, Stellite, castings and a host of possible solutions.
I can remember dropping over the side with a "great corrosion resistant steel", as described by the maker in my hand. I watched it rust right before my eyes as I descended. By the time I finished the dive, it was completely covered. Some of our friends and associates in the industry knew of our quest and we eventually came across H1. Then other steels came onto the scene and the rest is history. Probably 40 or so years from zero to options. Watching the development of the "Water Ghost" makes me proud to be part of this industry and it's persuits.
I really appreciate all of the "Real-World-Testing" we get from the Mules, especially the OC guys like we have here.[1]
