I'm pretty sure the fragility of glass stems from the cracks being stress points from which further cracks propogate. Under some circumstances (conditions when the cracks in question are not there) glass can become vastly more flexible than it would normally, so with that in mind I find it credible that Dust-generated blades of obsidian could be much less brittle than the regular kind. Besides which I've found that smaller individual crystals of obsidian are indeed much less fragile than the larger ones, presumably for similar reasons.
