Clips on Folders

[KenHash]

When did clips on folders begin to appear? I seem to remember Spyderco claiming to have been the first.
My folders from the 1980s do not have clips. But those from about 1994/95 do have clips.

According to Spyderco they were the first to include it in the design in 1981, which I take to mean that others had added them after the fact.

From their site:

The original Spyderco CLIPIT was introduced in 1981.We were the first company to use the clothing clip as part of our knife design.

Thanks. Does anyone have a folder with a clip from the 1980s besides Spyderco?
I have a Cold Steel Voyager with a plastic clip but not sure if it's from the 1980s or 90s.

I was under the impression that some of Terzuola's early 80s folders had clips.

I take off all my clips.
