To expand on this. I did a simple google search for 'barb nails' and got a lot of hits, but with no pics (or if there were pics it was of regular nails - i think they were since they didn't look barbed).

Are barbed nails really barbed? If so, anyone have any pics or something of what they look like.

Went to my local hardware store here on island (i miss home depot from the mainland), and nothing even close to a barbed nail (in name or in product).

I'm thinking of mixing this up with 10p nails as per Benjammin comments.
