I've been thinking of a brown leather hunting style sporran for a while, and there seems to be noticeable difference in the average costs for sporrans with a flap (such as a Rob Roy style) and sporrans with hunting style cantles. This is even true if the cantle is leather, and there is not a chrome, pewter, or other metal cantle. Also true with comparable levels of quality.

So I'm curious what accounts for this. I assume it's got something to do with the ease or cost of production. Are hunting style one's harder to make than ones with a flap? Are they just more appealing and so price reflects demand? Whether I make one or buy one, I'm curious about the difference. You sporran makers probably have great info. Hope I'm not asking for trade secrets!
