Rusty and Fully Jammed Pliers Restoration - My High-Earning Restoration Project!

RUSTY OLD PLIERS!
My friend gave me this tool 2 weeks ago And he told me that this tool belongs to my grandfather and said it's 150 years old When I saw its rust, I thought it was 150 years old. And I found a great project for restoration

THE RESTORATION Process
To restore it, I first needed to take off the rust, which was very hard. then I sprayed wd-40 on it But even after this its lock did not open, this was fully jammed. I tried very hard to take out its center pin Because it was completely strong because of the rust I started with a drill and then go and open its center pin after that I separated the two parts and left it in vinegar for 50 hours After removing it with vinegar it gave a very good result Then I cleaned it thoroughly with the help of grinder and made it shine like glass its center pin I made from an old iron piece which turned out to be very perfect And if we bought new handles and it's now usable again. During this process, I took full care of my safety. I used glasses, Gloves, And Head
