While we're talking about knifes. Is there any folding knife out there that could replace the good old box cutter (

It needs to stay sharp and/or be easily sharpened. It will be cutting boxes and the straps around them. I've noticed that card board is a killer for blades.
It must be exceedingly fast/easy to "deploy" as it will be used very often during the course of the day. Actually, it's more important that it is easy to fold back down, one handed. Any assisted opener will be quick to get out and ready to use.
A fixed blade in a sheath would be easiest but... it's moar funner with a folder
