I like the Rift, but I've never bought one. I've been using a 550HG Griptillian for 3 years now, and it's a superb knife. It cuts easier than my Delica, and holds an edge for a long time. The edge is also quite thin, though the angles are steep from the factory. I thinned it down to a 17 degree per side edge and maintained it with a 20 degree microbevel from the Sharpmaker. Even after thinning the edge angle down, it was still less than 0.015" at the top of the edge bevel. That's after many resharpenings on my 220/1000 waterstone. For whatever reason, it would also get very sharp with little effort. It would whittle hair after the 1000 waterstone. Most of my other knives could too, but they took a lot more effort and care while sharpening to get there. The 550 did it almost by accident.
