Not long ago, I had a railroad spike knife yanked from my hand swung around the buffing wheel, and thrown back into my left shoulder. I always stand just slightly off to the side, and this time it really paid off. Fortunately the blunt handle came first, and thus I was spared a trip to Dr. Riggs, but man what a bruise, and a wakeup. Now I understand what those cute little knive vices are for! I was always told the wire wheel is the most dangerous tool in the shop, but now, I believe it has a rival in my mind, same danger, different medium. As I am fairly new, I would like to alert any other new knife makers, clamp when buffing, sheesh, I almost wet myself, and of course, the day ended early.
