Is their any way to make a homemade grinder?

i feel it with my fingers ... i feel it with my toes dum dum dum dumm dumm the smell is all around me, and soo my feeling slows dum dum dum dum dum

no seriously use your hands or go to a headshop

 

Actually, you can go to WALMART!... and get a grinder for herbs and spices, works the same.

 

coffee bean grinder, small blender.

 

a lot of gas stations have cheap plastic ones under the counter

When i have to finger-grind i usually just take two pieces of nug and rub them together furiously, I find this method to be effective for maximum grindification.

 

Home made grinder = shot glass + scissors.

 

this. served me well and prevents finger fucking the buds.

 

yup!
only i use a little pill bottle. but same concept.
i see no need to buy a grinder. kinda like chopping it up myself like that anyway.
aaand, it's free.
