I don't think that maxamet properly fits the theme of the Tuff, plus it would be extremely expensive. The Tuff was never a cheap knife and with a big slab of Maxamet it would likely be over $300 street value. I like the knife and I'd buy a sprint, but I'd rather have it in 3v or Cruwear.
Not at all trying to start an argument. Just posting what I've read about how tough Maxamet is as a tool steel just like 3v.
Love to learn more about everything including these steels.
CPM 3V steel has the following steel composition (Note the high amount of vanadium content which produces some of the smallest and hardness carbides in knife steel.)
0.80% Carbon
7.50% Chromium
2.75% Vanadium
1.30% Molybdenum
Yet maxamet has 6% Vanadium and 10% tungsten.
Not trying to put words in anyone's mouth, or get into any type of argument ...
Hopefully only to shed some light on what I think may be going on.
I "think" my initial thought after reading your OP was similar to Surfringo comments (at least as I interpreted when I read).
Maxamet has VERY high wear resistance. You do not increase wear resistance and toughness (push/shove - one up the other down). I would not consider Maxamet to be high in "toughness".
In my mind, 3V exudes the character of toughness to a MUCH greater degree (from a performance perspective). Heck in my mind CPM10v (aka A11), D2, M4, A2, and CRUWEAR (mentioned by Surfringo) are all "tougher" than Maxamet (at least in my mind). If toughness primary goal, perhaps S7 (but I think that would be giving away too mush in the edge retention category, and also corrosion resistance).
The TUFF in 3V was "proper"ly done in it origin
Some people just were not tough-enough to handle opening & closing it with such a short lock-bar, and the model fell out of grace with the main-stream knife flickers. Many, I believe, simply did not have the patience or purpose to use and appreciate this Schempp design.
These are simply my opinions, and as we all know everyone has there own ... ;-)
