it-manV Gold steel means it's either V Gold 10 (VG-10) or V Gold 1 (VG-1.) It makes more sense for them to refer to VG-1 as V Gold as opposed to the much more commonly known VG-10, so I would guess that it's VG-1.
it-manWell, this is kind of a shot in the dark, but I'd guess 420J2, or something very similar - it's commonly used in laminated Japanese blades, since it's affordable, very corrosion resistant, and easy to work with.
salehonasiYes, V-Gold is conventionally used as a synonym for VG-1 even though, pedantically speaking, it could mean both.
Most of the more popular mid-range knives will use VG-10. Nenox/Nenohi knives (which use VG-1) are about 6x as expensive as Tojiro DPs. Some cheaper brands, as well as a few fairly expensive lines of knives also use VG-1. VG-10 is just better recognized and is commonly believed to be "better" because of edge holding, but it's also more difficult to sharpen, and less tough. But "super steel" sells knives and manufacturers have had a lot of success pushing VG-10 (and similar steels) on the general public. VG-1 is a less expensive base material but expensive doesn't necessarily mean best.
Having gone down the "super edge holding" knife road in years past, and having felt the frustration from trying to maintain a wear resistant ultra-hard blade, I can see the reasons why VG-1 might be a better choice for some users, but it's complicated. Depends on whether you do your own blade maintenance, how much appetite you have for time spent per session, and what kind of gear you have (soft stones, diamonds, etc).
The important thing is that one is not better than the other, they are just different steels with different pros and cons.
