Ok folks, I'm sure we are all familiar with the swords to plowshares quote? I have found an old harrow tooth on our farm that was at one time used by my grandfather( over 40 years ago) and I'm wondering if one can do the opposite...that is- make plowshares into swords (well, knives)? Will the metal be hard enough? If not, could it be tempered somehow? This would give me a piece of him to carry with me, and I figure I could plane one of his hand hewn red oak tobacco stick to use for scales. any thoughts would be greatly appreciated!! Dave T
