Are the edges of this piece creased, fused and burnished or is it a "roll" of material
sewn through from top to bottom. I've read several places that "rolled" edges aren't
appropriate for leather heavier than 4-5 oz, but most commercial items I've seen
(up to and including some "high end" briefcases like the old school, pre-China
Mulholland brothers) use it as well. Given that you can literally pull the thread
out of most commercial leather products with little effort, I'd venture that
"rolled" edges are a distant second to burnished in terms of durability?
