All About Pocket Knives

i have a old electricians knife
it has BIG ALLIGATOR snap on both blades but the scewdriver tipped blade is especially hard to open
was that common or do i need some different kind of oil???
ive laid the 3in1 oil to seem to help a little
maybe i just got weak fingernails compared to back in the 20s and 40s
thank you

how do you add more than 1 picture??

after you add your first add another. cool old knife. it might be tight because of warpage at the blade pivot pin or ?

What brand of knife do you have there? I think I have two similar....
both "MKLEIN&SONS Chicago", the scales are made of different material, one has a nice patina on it, but I know what you mean by a hard pull, both are hard to open the screwdriver blade, I nearly rip my thumbnail off trying to open them.

Do you have a "brass lock shim" between the blades on yours ?

Ratchet

its a old Case Tested knife
no brass in this one
i know what you mean about tearing a fingernail off...

There are two kinds of oil I use on real rusty knives.
Gunk makes a super penetrant oil, I think they are using the name Liquid Wrench on this product.

The other I use is called Hot Sauce. I get it from Bass Pro Shops. It is made for fishing reels, but works wonders to break loose a rusty knife.

There are a couple others with Teflon in them that work good too. One is called 80 & is made by Justice Brothers. Another is made by Slick 50.

They all seem to work well on old rusty knives, but my first choice ids the Gunk Super Penetrant. About $179 at my local Ace Hardware.

I hope this helps,
Dale

this knife has great snap and halfstops
just a bear dog to open on that one blade

Surely that is a typo? It better oil the knife itself and remove rust on it's own for $179

Well, it is oil, give it another couple years and it just may cost $179.00. I usually use Rem Oil with teflon, just because I have it on hand, but I also use Liquid wrench for a penetrating fluid. everything Dale mentioned is good and well regarded.
