Just got this about 30 minutes ago:
First reaction: HOLY crap that's a lot smaller than I expected. After spending about a month of looking at pics I guess I imagined it larger in real life. I am going to give the 3.5" a chance and that will probably be my casual EDC but the 3" is indeed a great EDC because it doesn't get in the way of anything and would be alright in an office setting. The 3.5" spanto will be more of a work horse and comfortable outside of work EDC.
CRAZY sharp, probably the sharpest knife I own it seems.
EDIT:
Also cant seem to open it using the flipper without flicking my wrist.
just ordered this exact same one. can't wait.
