I use a grinder with a pollen collector that works very well. It probably works better for me than others because the grinded bud sits on a screen and slides around when I go hiking. I take my grinder, pipe, and a lighter with me when I hike which is 3 days a week right now. I took all the kief out from grinding 5g of WW, 7g of Juicy Fruit, and 7g of random potent stuff. I made "sledge-hammer hash" with it and it turned out great!

I pressed it out to about 2MM thick, then I used a 3/8" crinkle pastry cutter to make individual hash disks. I brought 2 of these disks and got like 10 people high lol. 1 small hit from the kief hash and they were gone. I had 1 huge hit and I was flying...

The only thing I did differently from the origional post was put it in a toaster oven at 175 farenheit for like 5 minutes after I pressed it. I put it inside a damp cheese cloth and put the cheese cloth on a 4x4x1/2" glass plate that I chilled in the freezer. I liked it after 5 minutes in there because it stayed together better but wasn't hard.
