hummm , to me all pipes are good for hash ! that is just a matter of what ''good'' means for you ...are you searching for a water pipe ? a dry one ? a spoon ? hammer ? sidecar ? ect ....
well an upgrade from my corn cob pipe...
seriously something simple with a small, not too wide bowl and a longish stem.
glass would be nice but wood is fine too. thanks..
I like to use a glass "gandalf" pipe for hash. Here's a link I found to someone carrying them online http://www.newamsterdamcafe.com/12_Medium_Silver_Gandalf-details.aspx
. They don't have too large of a bowl and the long stem is so nice for cooling hits down. You might even be able to find one at your local headshop, they're pretty common here.
CapnVape has the right idea, get a glass screen to put in the bottom of the bowl to make your life easier (also easier to pack a screen then place it inside the bowl afterwards for some types)
Personally I always like GonG so I would recommend a sherlock glass section with a joint on the end to place bowls (or ashcatchers ) of your choosing.
Couldn't find a shop that had one for sale, but this is what I'm talking about http://ny-image2.etsy.com/il_fullxfull.71047422.jpg
I'm sure the purpose of the Vapolution Pocket Vaporizer isn't specifically concentrates, but I've had nothing but good luck using it with hash. As with most lighter-based vaporizers, too much heat burns.
