I found a SOG Twitch (maybe not). I believe we were on vacation It is pretty small with slick handles, a flipper, and cheap steel. I don't use it as it is not comfortable at all, and way too slick for its size to be useful. It didn't flip at all, and was butter knife sharp. I cleaned it up, got it flipping fast again, and sharpened it. I spent more time renovating it and sharpening than anything else, and that was more enjoyable than trying to use it. I was really intrigued by the way SOG got an assisted flipper incorporated with a back-lock. Pretty slick simple idea imo.
