Paleo knife?

I'm having trouble seeing the conchoidal fractures. Atlantia's post in #7 shows them quite clearly. Conchoidal fractures are what one sees when glass breaks. Is there a way you can indicate where you are seeing conchoidal fractures?

As for cryptocrystalline (crystal structure too small to see), I see crystals, and I see lots of evidence (the holes along the edge, for one) where there are fairly large crystals.
