The robust tip shrugs-off the de-legging and de-heading:
The blade profile was never going to be a world-beater for butchery, but it performed OK:
The fit and finish of this Taichung-made knife is superb. The lock hasn't shifted at all, there is no suggestion of blade play. The blade is perfectly-centered.
Appearance is an individual matter. I don't care what it looks like so long as it gets the job done. This knife gets the job done. Grip is fine. I'm not sure about the dimples.
It is heavy; I do not mind weighty knives but others may find this too much for pocket carry. I find it completely unnoticeable clipped in a pocket.
Sharpening has been straightforward on japanese waterstones, Sharpmaker, leather-backed micromesh (for convex). Edge-holding is more than adequate for my purposes (I took a video of paper slicing after full deer processing which revealed a good working edge was retained, albeit not hair-popping. I have so far failed to upload the vid to youtube.)

Corrosion: I have always cleaned the blade after coming in from shooting. With similar treatment Super Blue and K294, patination/staining has already started but the CPM3V remains as shiny as day 1, so far.
If you launch a knife with the name "Tuff", it is akin to wandering up to the nut-job in the pub, spilling his pint and saying "come an have a go if you think you're hard enough!" To a certain type of person, you are inviting attack.
So is the Tuff all mouth and no trousers? Can it walk the walk?
I say "yes". Emphatically. It feels as solid as a Shing Dreadnought, which is high praise indeed. It is not as slick or light as a Sebenza, and won't slice as well, but I have no qualms about leaning on it.
There have been some reports of lock failure since the Tuff was released, although I don't think any of those knives were ever returned to Spyderco for analysis, so the cause may be user error or modification of the stiff lock.
I had one episode where I inadvertantly disengaged the lock: this was because I was exerting an outwards force on the lock-bar while trying to release the bound blade in a very unusual cutting position (wrist bent to get under an obstructing grille).
The problem (for want of a better word) is that the knife inspires confidence and encourages you to lay into it, using it more and more like a heavy fixed blade. This is what caused the lock release when I was using it- I know because I replicated the circumstance immediately, yet could not provoke the lock to "fail" through other means; closure relied on me twisting on the lockbar while pulling sideways (ie. releasing the lock.)
My final thoughts:
Sometimes you bond with a knife immediately: the Spyderco Gayle Bradley (Mk1) is a personal example of this.
Sometimes you bond with a knife after a period of use: the Spyderco Manix 2 M4 fits in this category for me.
The Tuff, was an expensive knife so although I did feel that immediate bond
, I also felt it "owed" me something. Luckily it did not fail to deliver and is one of my most carried and used knives. It is quirky, but not at the expense of function (unlike the Captain, which I find quirky but compromised.)
Am I happy with the knife: Yes
Would I buy one again: Yes
Would I recommend it? Yes
you need a more discrete option than a fixed blade or you need a back up (or if you just like overbuilt folders.)
