Personally, I think the best waved knives are the Emersons & Spydercos. Unfortunately, I think Spyderco only makes a waved Delica, Endura, & P'Kal (If it's still in production). However, their other models lends itself to being waved, too, because their blade spines tend to stick out more than most other knives because of their thumb-holes.
Not that I recommend doing it, but my best waved knife is a waved Spydie Yojimbo. I got it that way & it works great. The P'Kal's another great waved knife, but perhaps not as utility oriented. I think the "secret" to a great opening waved knife, is to have the waved face forward in the pocket (Like on the P'Kal). I noticed that I didn't have to pull down & back, but just a little forward as I drew it out of my pocket. The angle of my front pants pocket aids the wave opening process, IMHO. Obviously, your observations may vary. Because Emersons are only set-up for RH carry, you really can't play around with that method on them.
Good luck with whatever you get.
