Very Rusty 19th Century Pocket Knife Restoration. I found this folding knife at a WW1 military camp site. The knife is very rusty. He lay underground for 105 years. The style of the knife is similar to the 19th century. This knife was made by a blacksmith. I decided to restore it. I removed the rust and preserved the blade. I hope you liked my restoration. #restoration #rusty #knife #rextorer
