Budsmokers got the idea. I used to have an electric grinder but that broke so I went back to my trusty scizzors, they are just a little pair about 8cm long. They work like a dream. I have been using them for about 6 months now and havnt bothered to buy a new grinder they are so good. They give you good control over how you want you bud to be.

I dont do it how budsmoker said though. I just get a nug in my hand and start nibbling away at it over a A4 size magazine or similar. Also try to cut using the part of the scizzors nearest the joint. Hope this helps.
