One of my hobbies is sailing. I've long considered purchasing a folding rigging knife, but have been unable to identify the one product that "has it all" and is "affordable." It turns out I'm not alone. Recently, in a sailing forum, somebody started a thread and posted a survey on the subject: Sailing / Rigging Knife (SailNet.com)
In post number 9 of that thread he refers to a white paper he's published on the results of his studies: Nautical_Knife_Market.pdf
So there you go, knife-makers, a challenge
: Design, build and sell an "affordable" "Perfect Folding Rigging Knife." From page 28 of the PDF:
For the blade shape, author David Seidman provides a good description in his book The Complete Sailor: It "...should be short and stubby, gently curved along its edge, with a thick back and anti-slip finger grooves. [Ed. note: I believe he refers here to jimping on the spine.] It should have almost no point at the tip and, in cross section, a gradual taper toward the cutting edge." Seidman is referring to a fixed-blade knife in his text, but I believe a folding rigging knife blade must have similar characteristics. One thing pictured in the book, but not mentioned in the text is a generous choil. Master Rigger Brion Toss, author of The Rigger's Aprentice describes and pictures a knife (again: fixed-blade) with a blade having identical properties.
One reason for that blade profile is that one of the ways in which a rigging knife is used is to cut rope by placing it on a block of wood, setting the knife edge on it, and giving the knife's spine a good, swift whack with a small mallet. I don't know as it's possible to design a folder that could be safely used that way.
Note that I've quoted terms like "affordable" and "perfect..." This is because I surely recognize that both properties are relative, and even somewhat subjective.

- A locking blade of quality steel and appropriate shape
- A dedicated and locking marlin spike
- A foldout shackle key that includes a bottle opener at minimum, perhaps a can opener
- A one-handed lanyard and carrying strategy
- Finish the design with true one-handed usability for all of it; that's it--nothing else
