Just personal opinion, but the canon references to crushgaunts are, to me, just gloves with spikes in. In my mind, I see crushgaunts as a more mechanical contraption that fits over your normal hand, like with pistons, metal support rods and the like. It's kinda taking that analogy of "Well it's a mesh weave that does it" as being not enough, and turning it into the extreme. Spikes are not enough; the idea of the gaunts is that they assist in crushing things so they should have some kind of indication of that.
