How do I frag Duncans?

[DracoKat]

One of my duncans has over 25 heads on it now. I wanted to sell it but no one's biting.

I think I'll try to frag them to smaller sizes and try to sell them- but I am not sure how to cut them? Do I use a dremel and cut a bit below the heads? do I cut at an angle?

You can use a dremel, but it will probably be hard to get in between them. You can just use a chisel on them too. Go straight down between the heads and through the base.
