    Hello out there. Never been on a forum before, so bear with me. I contacted Spyderco by email and by phone. The company statement is that they don't give out information on the blade hardness of their knives. This is a surprise to me. Maxamet steel specs give a hardness range from 64rc to 71rc. I have a Dragonfly in ZDP-189. It checks out at 64rc, and is does very well. If anyone has any information on the Maxamet rockwell on Spyderco knives it would be appreciated. Thanks

    Heard of an older maxamet pm 2 tested at 69, newer pm2 at 68+ ish. And a manix a 69 and 68 ish. Anything newer is likely around 68. But hey I’m just a dude that read some things, haven’t tested mine. Anyway hope this helps.

    Maxamet is intriguing stuff, would like to hear more from actual users. There have been some comparisons with other steels regarding edge retention, corrosion resistance, but nothing definitive so far. Spyderco is the only company I am aware of that is using Maxamet.

    I have a Native 5 in Maxamet, and I really like it. I have only used it so far breaking down cardboard, and it has kept up with and surpassed most of my CPM knives - 3V, S30V, and S35V, but not CPM 10V, that steel still has no peer in my collection. I will hopefully get around to testing it with some rope, the cardboard cutting depends a lot on the geometry of the blade, and the Native is a little thicker than some of my other knives.

    I cut about 50 ft. or so in one session, and it still tree topped my arm hair, and a quick strop brought it back to full sharpness. Not very scientific, but so far, I'm pretty impressed with this steel.

    Good to hear of some practical field use of Maxamet. Have you done any sharpening besides stropping?

    No, not yet. I'm hoping to do more this weekend.

    ZDP is nice. Maxamet has better edge retention. Also appears to be more brittle and is harder to sharpen.

    I've sharpened Maxamet quite a bit and reprofiled 3 edges. I used diamond matrix stones. No issues at all. I'm sure some others (silicon carbide, cbn, etc.) are fine as well. I think it would be tedious with softer stones and I'm not sure what kind of edge you'd get.

    Some experts have posted on how to best sharpen it here.
