I have been carrying a Case/Bose Hawbacker Rat for about 7 months everyday now along with other knives (including a full size ivory BPK from Tony frequently). I never expected that there would be a knife from a production company that would be good enough to earn pocket space in my pants. Well, I was wrong!! It is terrific.
If you haven't already checked out the collaborations, I suggest you do so. They are excellent knives.
I would love to have one of those Lockback Whittlers.
