Automatic knives?

[joatmonknife]

I have had these knives for about 30 years. When I received them, they were very dirty. It took me a while to figure out how they worked. By pressing on one blade, the opposite blade will open. There is no brand name, only a patent no. 24630. If anyone has information, please let me know. By looking at the link below, you can see more details about the knife.
This is my first time to post, hope I got it right.

They are assisted open knives not really switchblade/automatic knives.

The patent pretty much explains it all, I have seen them with various manufacturers names marked on the tang. The inventor sold the rights to different manufacturers to produce them under his patent.

Nice find thanks for showing them

Very cool knives in great condition. Not something you see every day........or week.......or month.....or possibly year.

I've been collecting pocket knives for well over 40 years and still don't have any of those. I think they're really cool. Thanks for the pictures and the patent info. Excellent first post. Welcome to AAPK.
