Those metal ones that usually got some type of picture on it are commonly "made in china" but I'm sure they do the job. I had a nice solid grinder, guy gave it to me for 20usd, just broke two teeth out of it last week... nooo idea wtf I did, i guess it had some godly stem in it that managed to sheer off two pieces of stainless steel...

Anyways yeh I use a grinder, I've always known about em, but never gave 2 shits about em... I go into headshops, see all the bongs which I am sure area great, but fuck if I want to clena that shit, fill it with water, keep it in a safe place.. hell no! i got a box of blunts and 2 chillums in the drawer and that is all I need! What made me go buy one though was the kief catcher, cause it always pissed me off breaking the herb up on my hand or a piece of paper and ending with a bunch of dust I can't do crap with..
