I've seen the term thrown around. is it just another name for a slip joint or is it something specific?
 
A "clasp knife" refers to a knife with a basic curved frame (like a horn). Think of fish knives, toothpicks, Spanish navajas etc

This knife (not mine) would also be considered to be based on the "clasp knife" concept:

The first I ever encountered the term was in Great Expectations, by Charles Dickens. The ex-convict. Able Magwich carried one. So the term was in use by Dickens time.
 
Thanks Blues! Any idea where the term came from?

Bernard Levine (and his forum) would be the best resource for that answer imho.

I've heard a couple of answers and prefer not to inadvertently mislead.

One of my favorite stories, Carl! :thumbup:
 
Growing up in England..
In general usage, a clasp knife meant a large folding knife

What is now called the "British Army Knife" was called a Clasp Knife

The words for folding knives were:
Pen knife
Jack knife
Clasp knife

Then there was a Sheath Knife
 
The traditional folding hunters we know of such as the buck 317, the uncle henry 225 & old timers like 125 are also regarded as clasp knives even though loosely referred to simply as folding hunters.
 
Having a curved shape means that there's often a reasonable amount of blade to get hold of as in pinch opening. These knives tend to be larger I'd say. Oddly enough, clasp means in jewellrey, a device to fasten things together. I wonder if Clasp knives originally had some kind of catch to keep the blade open? A primitive lock sort of thing?

According to the Oxford Dictionary, a clasp knife has a clasp to keep it closed
 
I always though the origins of a clasp knife was a one bladed folding knife where the blade, when opened, was held open by mechanical means not friction. This encompasses a lot, it could be help open by a spring (Sodbuster), locking ring (Opinel) or other device (Okapi).
