Yeah, the older ones were made in Japan by G.Sakai. G.Sakai also made one that was extremely similar (but with very slight differences) which they called the Preppy, also in silver twill (but not titanium). Those were easily found on eBay but the supply seems to have dried up. I bought a few Preppys, and I have a few AGRs, and I can tell you that the AGR is the superior knife, although the Preppy is quite nice too. Either way, they're extremely thin and light - so much so that they absolutely disappear in the pocket or even a wallet.
I picked up a newer carbon fiber AGR that's made in China for cheap off eBay, and it was severely disappointing. Thinner steel, almost too thin, unequal texturing on the carbon fiber, flex where the Japanese ones are quite solid despite being also very thin, etc. Then when tightening one of the handle screws it sheared right off. I wasn't torquing very hard at all (it's a T5 or maybe even smaller - it's not like you can twist it that hard). I would have purchased one with damascus steel if the rest of the knife was quality, but it's far from it.
