VG-10 is Japaneese while S30V is American cutlery steel. Knivesshipfree.com has the F1 blades handled by Bark River and sheathed by Sharpshooter, making it a US made product with an imported blade, if that's important to you. Nice handles and sheath - beat the heck out of rubber and nylon.
I personally love S30V - but it isn't all created equally. Benchmade and especially Buck, with their Paul Bos heat treating, do a great job with it. My BM 610 Rukus is a handful of 4.25" x .150" S30V blade - and my BM 630 Skirmish's 4.3" x .160" recurve blade of S30V is even more so, despite it's Ti handle. Both are armhair poppers and seem to stay that way. The Cabela's 'Alaskan Guide' Buck 110 is a Paul Bos S30V bladed knife at a decent price - that comes as a shaver. My AG Buck 192 is still a shaver, too, as is the #347 Vantage Pro. My Spydie Native in S30V was an EDC, where it cut everything, for a year before I introduced it to the Sharpmaker. Even my Gerber Stag/S30V is a hair-popping keeper. My S30V experiences have been great.
My only VG-10 bladed knife is a Kershaw #1993-2 'Gentleman's Folder', which mainly rides the pocket on Sundays. Still a hair popper, it was a razor... and only openned a little mail that I remember. Cute knife, however. Not a fair test of VG-10 - and since I haven't chopped/battoned with S30V, either, perhaps the Jury is still out there, too. Still, I'll stay with S30V...
