The Kershaw Zing with the grooved blade has been my main daily carry for several years. Same size as a mini griptilian, holds an edge well, attractive shape, etc. Sandvik 14c28n made in USA. I'd like some new scales (micarta specifically) for it since the originals are a little beat up but I don't have the skill and it's not worth high priced custom work. Solid well made knife though.
I've got a kershaw shuffle 2 I carry occasionally, it's a good looking knife but I've come to realize I don't care much for tanto blade shape, have considered re-profiling it to a more drop point shape to make it more useful. Scales are a little cheap feeling. Nice profile though and anything with a bottle opener attached is a plus.
