This one has been running a bit, but still active so I'll chime in too. Unfortunately I am limited by a blade of no more than 2.5 inches to avoid it being considered a 'dangerous weapon' at work (I switch to more realistic knife at home). I've been carrying the Boker Sub Com folder for about eight months now. To me this is not an ultimate design, but it has proven comfortable to use, sturdy and effective, which is all I can really ask. The liner-lock, though not my favorite system, has provided reliable and solid lock-up every time. Since it retails in the mid-30's, can't be construed as a weapon (so I can drop it in the change dish at the metal detector [not at the airport] and get it back again), fills my hand well despite its small size, and allows me to go with something sturdier than many small bladed knives, it fits my need. Maybe not yours, but I hadn't seen this one mentioned and it works well for me.
