Vintage Folding Knives

Not sure why I have developed a fetish for old blades all of a sudden. Must be harking back to my childhood when we used to sharpen sticks and throw them at each others heads. Carry one every day and probably use about 3 times, so its practical as well as fashionable.

Here is a pick of my collection so far. All Sheffield Steel apart from the larger one.
The larger one is US marine issue lock knife, not a folding knife. Difference being about £5000 fine and up to 5 Years in prison if caught with one.
