Flea Market Finds - Restoring a Vintage Swiss Army Knife 

I've had reason to restore a fair few Swiss army knives and multitools in my time as a collector, and in that time I've developed a simple, reliable system for cleaning, restoring, and maintaining these tools. Whether they've been lost to rust for many years, or only need a little tuneup, this process is sure to provide results.
Rather than washing the tool in something that may cause rust down the line, I prefer a liberal bathing in some good old WD-40. Once the majority of the gunk is gone, a brass brush will help fight through the more stubborn spots. Watch the whole video for more tips!
