A couple points should be made here:
1. Steels and HT methods are constantly improving
over time. Weaknesses may disappear or become less significant, and previous measures for certain properties may improve. Thinking that all generalized statements for steels will always hold true and unchanging over time can sometimes be a little ignorant.
2. If you check out what some people make 3v capable of, you may think twice before saying that folder batoning is stupid. For something like 3v or 4v ( or Z-wear, the toughest monstrosity of the bunch), common sense will tell you that the lock or pivot will fail before the blade does, and this is the main reason(I think) why people would say such an attempt is only going to be done by silly "tough-afi's". Now if we theoretically can baton the folder with the lock disengaged though, meaning the handle is freely swinging loose, we would have a situation not too much different than a fixed blade in a perfect, ideal, theoretical situation where a disengaged lock = never enough force applied to the pivot or handle to cause any damage.
I would be confident in batoning something as "thin" as a Para 3 blade, I really would not hesitate to baton it through anything if it was only the blade made of 3v. Assuming you could achieve similar harm prevention by having the lock disengaged, I think, is somewhat fair at least. If anyone does not think 3v could hold up to woodworking/bushcraft level hard use with the thickness and geometry of the Para 3 I would tell them that they are wrong, and to watch some videos of 3v made in the last couple years or so.
3. Like others have said, and I feel this needs to for some reason still be reiterated for some, toughness is not only useful for hard use. Any damage to the edge or blade itself that may otherwise happen to a typical folding knife steel that can come from pushing, pulling, twisting, and impact
is going to be mitigated to a much greater extent. Like others have stated, toughness is great if your normal tasks can risk the blade getting jammed into nails, staples, or maybe if you are going to be cutting a lot of things like zip ties for instance.
4. PM2/3 owners - how many times have you lost that lovely pokey and pointy laser-like tip on your knife? To me, that tip is one of the top features of the knife that contribute to its widely recognized greatness. Most of the time I lose the tip of my knife, is not due to sharpening, as you can be careful while doing so, but rather from an impact from dropping it or having it slip and jam into something very regrettable for the tip to jam into. So kind of continuing point 3 from above - there are many situations your knife can get into where toughness matters... a LOT! Many of those situations will be accidental as well
. If anyone says they have never messed up their tips before, they are either absurdly OCD/obsessive (no offense), or their knives are all found in their playroom along with all the hot wheels and stuffed animals.
If you feel you have been irked even by the slightest bit after reading through my post, please accept my sincerest pre-apology and just know I usually am exaggerating half the time and joking for the other half. I do feel like the "anti-tough' and the knife politics and ideals they chose to take on and propagate have tended to be quite unfounded on any practical logic, and rather has become one of those stances some people chose to have so they can seem
to have a superior level of sensibility than others and/or just to have an excuse to be demeaning and egotistic. I hate to cause any conflicts or division among what should be a happy and united group of bros (and sisters) who all share a common sense of stoke for pieces of sharp metal with holes in them, but personally I feel the level of intensity and bad vibes stemming from this toughness debate has just been getting a little ridiculous, especially with it being so subjective at times. We can always try to assume less and also strive to be more kind and open-minded than we once were before.
