Always like seeing these!Here's an interesting combination.
The split handle design was actually used by European cutlers in the 1800's. I've seen pictures of examples. In the 1960's/1970's Hackman produced what was marketed as a "folding Puuckko" knife. I bought one and enjoyed carrying it because it really was close to carrying a folding fixed blade. Nowadays, it counts as a "balisong" and I cannot carry it.
Enter Cold Steel. They appreciated the same strength that I did and found a way to make a split handle design which was legal to carry. They did that by putting a spring on each part of the handle. It cannot be flipped open. It can't even be opened one-handed. Behold the "Black Rock Hunter". No longer made. I think not enough people shared my appreciation for the absoluteness of the "lock". It absolutely cannot fail. But I think it makes and interesting combination of a modern adaptation of a traditional pattern.
^ which is the traditional and why, Frank?
The Hackman is actually a traditional design.
Why? Because split handle knives have been made by European cutlers for over 150 years. Not a common pattern, but I have seen them in the Levine Forum. My family had a couple of split handled knives when I was growing up which easily predated the initial release of the Buck 110 . Those knives were very similar in design to the Hackman.
The Cold Steel is the modern
Why?Because they put a spring on each handle segment to hold it closed so that it could not be opened without the use of both hands.

Here is a thread from Levine's forum trying to identify a split handle knife made in ~1910
