Out of all my Spydercos, highlights including: XHP Manix, Chokwe, Leafstorm, Urban, UKPK, Stretch FRN ZDP, etc....
My favorite knife is my UKPK Drop Point. It carries perfectly. It's sturdy. It's sharp. It's easy to use one handed. The blade looks cool. It's reliable.
And I really don't think people are cutting stuff that needs a lock 90% of the time anyway, myself included. So It's my favorite knife and it can be yours too! Even if it had to be drawn for SD, chances are the sight of a knife would cause a petty thief to run. Well, if faced with a confrontation, I'll probably either run or pull a Ruger LCP. So yeah. Slipits do the job.
