All About Pocket Knives

I have two Remingtons that I need information about. I think I could make nice knives out of them if I had blades for them. I just thought I’d ask. If these are stupid questions, someone please let me know. I’m new here.
　
One is a Yellow Remington two blade with springs like a bear trap. I’m also not sure what to call this knife if anyone can help me there. It looks kinda like a Sportsman Peanut? I’ve seen some old ones called "Regular Jack." 3.5" long closed. I’m also not sure how old it is.
　
The other is a ladies leg shaped Remington two blade *LIKE* the one pictured. The blades are sharpened completely away - Almost nothing but the tangs left.
　
Just wondering if anyone has blades, Ideas for different blades that would work or donor knives for either of these? They sure would be appreciated.
　
　
Thanks,
Danny

That yellow Pyremite Remington is probably a R 155. I'd call it a swell end jack. If I see the tang stamps correctly it was made between 1935 and 1940. Surely you wouldn't consider replacing the original blades with new ones. That would destroy all the authenticity and character of the knife. Granted the blades are short but I'd much rather have it in its present condition than after it has been worked on. If you want a knife to practice on, a Rough Rider would be a good choice, you can buy one new for just a few dollars.

The Remington leg knife is a repro

The yellow Remington in its present condition is worth around $ 25.
If you put blades in it from a modern knife it'll be worth around $10.

I know no onw would ever really do it... but...

Isn't there a law against putting a Chinese blade in a vintage Remington knife?

Please God let there be a law....
