I had one in charcoal grey and black. I liked it, but didn't love it enough I guess not to let it go. Granted, the blade was awesome, but I found it was kinda hard to flip open with the thumb studs. Maybe it was the way I was holding it in relation to my hand size. Anyway, the reason I say "had" is because I traded it for a ZT 0350 Combo Blade. I took it to my local (pretty crappy) knife shop and that's the only one they would do a trade with me for, even though I also had a 707 Sequel, 3150 Impel, 585 mini barrage, a few mini-grips (one Ritter), and a slightly used 940. I really wanted my first Zero Tolerance, and the ZT 0300 was just too expensive for me because I didn't have any cash at the time. So I made the trade one-for-one. Otherwise I probably would have held onto it if they were willing to consider some of my other blades. I gotta say, I do like the ZT better. Assisted opening with a great "thwack.". But anything wrong with the Rift? No, I don't think so. OP, maybe it's just in higher demand, so that's why people are selling??
