no i have not heard about a full glass grinder... u can google it tho

I once saw a badass grinder with anti-static glass only being used on the top and bottom flat areas but rest was steel or somethin

but i dont like the idea of having more glassy things for my weed part of life! Already pipes and bongs are made with glass and when they get broken thats just fucked up!

for pipe (or i should say light) smokers, grinder is no necessity if using exotic herbs, it will probably waste more of your precious trichomes than do any other good!

but if u smoke dirt weed, then who knows maybe u need a commercial electric one lol

but there are some really cheap and practical ones, electric or manual, plastic , iron or other stuff, on ebay,
