Spyder Hole Origins

[R.Russell]

I'm sure somewhere in the 50 pages my search returned there's a mention of the origin of the Spyderco hole that assists in opening.

As a collector of Bob Lum blades (he is a genius IMHO), I'm curious if it's his invention? I know he worked very closely with Spyderco and began making knives before they were even a company. Were there one-handed openers in traditional Chinese knives???

AI credits Spyderco with the CO1 Worker in 1981, but Lum was making folders for at least 5 years by then...

Any insights appreciated.

Sal has a forum on here and responds and posts pretty regularly.

Well, according to a recent David C. Anderson revelation on YouTube, the Glessers are from outer space. So it's possible the design is a traditional feature from their home world.

Spyderco (Sal’s) patent for C01 Worker in 1981:

It could be argued that Scagel had opening holes prior to any of them. They were not for one-hand openings as they replaced the nail nick.

I'd love a T-shirt with the worker patent on it

Yes, I see that Glesser patented it but as you point out it had been done before.

What about Bob?

Bob T. did that because he thought Sal's designs were ugly. Personally, I thought the exact opposite.

I've seen Sal's first prototype folder with the opening hole. It's not pretty, but it works with one hand, unlike Scagel's.

Bob Lum was a genius and a true artist, but one-hand opening was not one of his innovations.
