You can go either way. You are not going to capture an opponents blade for very long, or very well. The best you could hope for would be a slightly controlled deflection, and much of that would depend on the sharpness of the blade you may try to deflect. More sharp, more bite, more control, but in reality, probably not enough to be of much worth. The Musso is a thin channel of about 1/32", soldered to the blade. The Scotch knives I saw photos of, were solid, inletted, and soldered in place, or possibly attached by mechanical means. The brass back, in my opinion, would be something seldom acually used, but would be there and ready, if ever an occasion arose. I believe if the brass back was really all that useful, you would see more of them in fighting knives, then, and now. They do make a Bowie look even more cool, and deadly though, don't they? :grin:
