I suspect old tools may have some hard steel, but may be very reactive. They rust easily. I have a few things from my grandfather, who was a foundry man. Everything in his tool box, even coated w. oil, was rusted when I got them. I have used one of his triangular files on my sticks. I think it may originally have been used to sharpen saw teeth.
I have no idea what kind of steel was used in your draw knives. I looked up "James Swan," and saw that was a respected name. It should take and hold a good edge, but, I suspect, be sharpened away w. strenuous use.
