What exactly would 4V give me that is enough improvement over M4 and Rex 45 (both of which I have) to justify buying it? For folder use improved toughness is not a determining factor for me, as the others I mentioned are fine in that regard.
Toughness without sacrificing strength. Probably more edge retention than M4 given the hardness difference. Most likely has more strength than both M4 and REX45. Usually, toughness + hardness = strength. Sharpening response could be best as well, depending on what you look for in an edge. The apex comes up very crisp and fairly aggressive rather quickly.
Spyderco is killing it on the 4v. I have one of the 4v Shamans, and it has been performing incredibly well. Great edge retention and edge stability. I had it tested in our QC lab today, and it hit 65.2! I saw the Para 3 models were 64+, and they didn't hold back on these either.
Interested to know what the k390 PM2 is at if you’re able to do it. I’ve seen some posts over on Facebook and they were getting about 61.
