Are you kidding Aaron...waste it? Angle iron (bed rails) is a knife maker's best friend. Machine and vise stands, work benches and even home made grinders are all made out of that stuff in most shops.
Heck, I'd run out of welding rods in about 2 days if I had a pile of those things. ;~)
Oh, and you can use it for fittings on knives. It'll take bluing really well and it's easy to work cause it never gets hard.
Wish I weren't on the far end of Kentucky from ya, I'd help ya use it up! ;~)
