Pretty sure that spyderco invented the round hole as an new way to one hand open knives. There was some type of lawsuit between Spyderco and Benchmade at one point. The resolution details haven't been made public, but benchmade still uses a round hole in some of their models. Pretty sure that Spyderco owns the patent that defines the round hole in a blade as an opening method. IMHO it is the single best way to make a one hand opening knife.
I have heard a few stories about this. The most pervasive is that Spyderco was only able to claim infringement if the holes were the same size.
I am familiar with patent law and the patent process, and the opening hole is definitely an improvement that qualifies for patent protection, but personally I think it's borderline cherry picking. Like others have pointed out, many simple features are in the public domain in knives, and a hole is about as simple as it gets (anybody with a drill press can add one to a blade). Does anybody know when their patent protection expires?

Really? I mean, that is great that you like them! Whatever works is cool, but can you explain why? When I press a non round hole with my thumb and twist it, the pad of my thumb kinda pinches and has to rub against the hole in a way that isn't painful, but is really noticeable and weird.
I believe the hole is trademarked, not patented.
I didn't know that. Still a big win if its true... Any smaller and it does get too cramped and harder to deploy, any bigger and the hole just gets ridiculous. Knife-holes I'm talking about. :thumbup:
I first heard it from a guy that owned the Benchmade knife design the proceedings were over. Benchmade was able to keep producing the model, but discontinued it later because it poses a unique marketing problem. When you're in dispute with other companies that are well liked, it's always going to have an effect on your brand perception. It was a calculated move based on business, not as much a nod to respect. The difference in the dimensions were very small according to him.
kind of a b.s. move to try to trademark something that's over 20 years old at this point.Yep the round hole is a trademark of spyderco. If you see another company using it, they either are licensed to do so, are doing it illegally or dont know they should not be doing it. I think the reason you dont see the round hole on the byrd knives is because they wanted a brand of entry level knives with their own identity. If they used the round hole they might as well call it a spyderco. But I also have to assume they want to reserve spyderco name for mid to high level knives.
