812BT.... had mine for two years... its small but fills your hand, you can get m2 or 154cm (now). It has a thumb hole (which is never obtrusive during cutting or sharpening and it doesnt run the risk of comming out or breaking off). It has titanium liners, good clip position... good clip point blade tip yet not so fine that it snaps off all the time, its easy to reassemble after cleaning (which you shouldnt do, but ive done it and its not too bad). I love it... i tell everyone to get one.
