I feel like the logic "X steel should never be offered because Y steel does what X does, but better" has no end. And if that logic were actually followed, spyderco wouldn't have so many different steels in a single model.
The idea of the 3v knife is just that one you would grab when you encounter a situation where there's no way you'd use your average spyderco sprint run knife. The types of situations where decent force (but not more than a folder can handle) is needed for a cut and the blade is likely to make contact with something that will cause severe edge damage. Some of us have jobs where situations like this are unavoidable and would really value a workhorse knife we aren't afraid to pull out for the toughest scenarios.
An example that MAY highlight the kind of edge damage I'm describing:
If I had a pm2 sharpened at 30 inclusive and I was whittling a 2x4 with moderate force and struck a hidden nail, which steel would yield the least damage to the edge?
3V, 4V, Cruwear, M4, or 52100?
Rockwell hardness aside, I suppose it would matter at what speed you struck the nail, as I'm inclined to believe 3v and 52100 would do better if the nail was struck quickly.
So as you can see my concern is simply preventing edge damage. A hard work knife that can take some abuse (within the limits of a folder). Is 3V simply a bad choice for this? Are the other steels I listed above THAT much better?
This is a huge oversimplification, but I was under the impression that 3v has better wear resistance, edge retention, and corrosion resistance than 52100, with toughness being close. People seem to love 52100. I do understand that for most people's uses 3v simply isn't the best choice. But the same could be said for s110v. Hopefully this clears up some of what I do understand as well as what I don't understand.
Its not that 3v is a bad choice, it's just not the best choice if we have 4v or cruwear as an option.
People dont realize they aren't losing much toughness.
My experience comes from providing CPM steels for Malanika Puukkos which are small wood carving, Bushcraft blades. People would BEG for 3v.
The problem is I couldn't give in to their demands because they didn't understand what they were asking for, they are excited about the REPUTATION the steel has while I had to make choices about the REALITY of the material rather then it's perception.
3v on a blade at 60hrc doesn't have the strength to support a 0.010" edge for woodcraft. Its not that it was horrible, it's just it would roll and blunt sooner in actual use.
That malleablity and ductility that makes for excellent impact toughness is completely lost on a small knife.
The impact toughness doesn't translate directly to edge stability
4v was clearly a better choice and just as tough as it needs to be even at 64hrc, which translated to MORE edge stability if you define edge stability as the edge holding it's shape under extreme stress which includes NO ROLLING
If 3v and 4v we're both at 62hrc..
4v would still be the winner if your using extreme geometries <0.010" behind edge.
Because if one edge rolls and the other does not with the same stress. The the one that holds it's shape is the winner.
That's why Jim Ankersons Knife is so exciting HE gets it.
We get the strength for thinner geometry AND the toughness.
If Spyderco made a 3v pm2 they would make money regardless, but Darby (Bearfacedkiller) NAILED it in his post.
Think geometry not steel if you want durability
You have to remember that cold chisel and metal cutting shears don't use legendary steel.
They use thick geometry at the edge and behind the edges since they aren't cutting but sheering and chiseling.
So if people are using there knives with disregard to what the edge makes contact with then Beef up the edge, having 3v isn't going to solve geometry. 3v will go insta dull and blunt if used on ceramic or if your trimming material with the tip running on metal just like any other knife steel.
MMG renovations and other have mentioned that 52100 isn't appropriate in a folder.
I wouldn't say that.
It's not very wear resistant but alot of guys like to polish there edges which reduces the aggression and wear endurance.
If your polishing your edges, 52100 might make you really happy.
