Thanks all for the input.
So I perused Northern Tool and saw the reviews on crappy, "affordable" anvils. I had been warned.
I found scrap a place in town with a couple small (50#) anvils for $200 each. Yowsers. While there, I stumbled upon a piece of a train track and I thought hell, I could use this thing.
So I got the tain track chunk, a hatchet head and several files for $35. Picked up some real charcoal a 2# hammer at menards.
I roughed out a knife tonight to prove I could do it, but I now need to make a decision about the forge. I COULD make do with the fire pit and a hair dryer, but there's some sweet old cast iton forges on craigslist...
I think if I heat a file to 1800 degrees in my fore pit I may lose the fire pit!
