In Jim Hrisoulas's book the Complete Bladesmith he says
"Fullering the blade, or creating longitudinal grooves along the blade, servers two main purposes: it lightens the blade while making it wider without sacrificing cross-section strength, and allows for a more flexible blade.The fullers were neither invented for the blood to run down nor to prevent the suction of a body binding the blade in the case of a stab. These are old wives' takes based on fantasy not fact."
I hope it was ok that I posted that excerpt. It really is a great book. -
I tried forging with corn today, but I didn't have much luck with it. First I started with a peice of 1/4x2 leaf spring, I had a lot of trouble getting it up to forging temps. After that I tried forging with some 1/2 inch round stock. I was able to get that to orange in about 1 minute of so. On problem that I was having was that the corn underneath the stock would burn up to fast that it would hollow out, and the leave the stock with nothing under it. I think that there is a lot of potential in corn forging, but I believe that I would need to do some experimenting on the ideal forge design, and the amount of air flow. I did find, though, that the corn clumped up very well, almost like coal.
Here is a picture of the fire.

some advice about rr spike knives
in Finish and Polish for Knives
Posted
I would suggest that you soak it in vinager and then use a wirebrush wheel on your angle grinder. The finish that you from a wirebrush is very interesting and I believe it might actually look better than a mirror polish would on a rail road spike.
Sure you could use a round file and then sand paper, but I think that you might be better off working on good steel. I am not sure that a rock tumber would work, see the way a rock tumber works is it takes off all of the high spots from the stones. I would think that you would only get a polish on the very ousides of the knife and you would also lose your nice sharp twists. Plus it takes several weeks for a rock tumber to work on a stone.
Good luck on what ever you decide, and don't forget to show us your results.
