Many years ago, gerber had the "exchange a blade" line of folders. The lock release also released the blade completely from the handle for ease of cleaning, and so that the user could switch between a few different blades. This was the knife that I used up until last year for cleaning game animals. I switched to a fixed blade of different make, but that folder was easy to clean. Seems that this would work in an easily cleaned kitchen knife application.
For whatever reason, when my wife and I go to others' homes for get-togethers, I always seem to be the one drafted for cutting, slicing, and chopping duty. In my experience, most non knife nuts have a drawer full of non-sheathed dull kitchen knives. A folder would allow for a non knife nut to store a sharp knife in a drawer without the blade being a safety issue and without the edge being dinged by other metal objects. Of course it would probalby become just another dull kitchen knife soon enough, but at least it would be well made, from qualty materials, and have a non-exposed blade when stored. It would also be handy to keep in the car for those, "away form home and need a big sharp kitchen knife" situations. My EDC is just not big enough for brisket duty.
