Thanks, Hushnel...
From a users perspective, I have always been more comfortable with a pinch grip steel, as opposed to the knuckle wrap type. Some of my favorite steels were 2-3 inch sections of mill files. The period correct pieces were alot thinner, too. I think this may have been for 2 possible reasons... Either they were trying to cut down on weight or save money on materials... I tend to think the later because many of the "home made" artifacts were beefier, while the trade company models were on the thin side. To me, the heavier ones are easier to use.
The weight and length of the wrapped one really helps it throw those sizzlers... they were reaching the ground when I was testing it. The small one produces decent sparks for such a compact steel. I figured you'd put them to good use. These ones are going up on the site.
