I actually just put an order in yesterday for a Fehrman Last Chance. I had a question for Eric Fehrman about 3V, and this is what he told me.
My question:
"Lastly, I know the 3V steel could kill Superman himself, but in a
worst case scenario, would it chip more like a carbon steel or roll
like a spring steel?"
Eric's answer:
"3V is a merciful and just steel, so I'm sure it would never want to do
anything to hinder truth, justice, or the American way.
Actually 3V can have a tendency to do both depending on the
circumstances. Hard impacts on very hard objects (steel, stone, etc)
that are small (alot of impact focused to a small area) you can
experience some small microchips. When chopping more blunt objects or
pushing slowly into a very hard object you will tend to experience a
rolled edge."
Straight from the man himself. Personally I love the look of the handle, but I have not held one yet, so I can't really speak to it. As far as the 3V steel edge rolling, that is a good thing instead of chipping. It is then easier to hone the edge back to straight/sharp, although under normal use I wouldn't expect it to have much deformation over a long time period. This is just based on readings as I haven't handled any other 3V yet.
As far as A2 steel goes, I think you'd be happy with a BRKT Bravo 2 also. It would need to be sharpened/stropped more so than 3V I think, like bearcut said, but my A2 steel Bravo 1 holds an edge for a ridiculous amount of time.
Depending on what your intended use is, I don't think comparing the shape of a Bravo 2 and a Fehrman First Strike (7.5" blade) is apples to apples. If you want a chopper/all around knife, look more at Fehrman. If you want a slicer/bushcraft, look at the Bravo 2 (yes I'm calling it a slicer even though it is kind of thick for that designation). Reason being is the Fehrman blade is taller.
INFI is a fantastic steel. Is it leaps and bounds better than A2 or 3V? Probably not, but I do like it better than A2. Is it worth the money? Definitely. For your stated intentions, I wouldn't get the Scrapper 5 because it is not a 7" to 8" blade.
I can't really speak to VG10 for this size knife, but my folders are definitely tough, not "brittle."
