Not quite, but quite good
Lynn K.
This should really be about a 3.5 star rating, just doesn't quite make it to 4 but it is a nice knife. Fit and finish are very good, deployment is a little stiff initially but will probably wear in. My biggest issues are with the size of the handle compared to the blade. If it were maybe 1/4" longer and about 1/8" wider it would fit my hand much better and might get that 4th star.
nice knife
overall i like this knife for the price. it is a small light EDC blade that gives you a good amount of usable blade for the size it might look a little awkward but once in hand it is very comfortable. one negative is the super stiff detent. combine that with a super slick polished flipper tab in such a small package and i have found it difficult to deploy consistently. hopefully over time this will smooth out. from what i can tell this is due to the detent ball being rather proud in its position (50+ percent is exposed) causing it to almost lock into the detent hole. really really wish they would have used some kind of texturing or jimping on the flipper tab it would have made a world of difference
