omg a coffee grinder??? no, been there done that, and I learn from my mistakes.
after using a blade type coffee grinder you WILL notice alot of kief coating the entire inside of the grinder. that kief use to be in the bud.
What I have learned is the less we handle the nugs = the more we get out of the nug.
using your fingers to break apart a bud to vape or smoke also looses alot of kief to your now sticky fingers.
My first grinder was a wooden one a basic 2 piece with alot of metal pins in it. needed cleaning ALOT
Then I got my last grinder a Spacecase medium 4 piece b4 they had magnets. I got that in the late 90's and is nearly 20 years old
this is my go to grinder anytime i am looking to vape or smoke some bud, It gets ground up In my old spacecase 4 piece.
I have recieved various freebie grinders and was not impressed with any of them. my Spacecase still grinds very well. when it gets difficult to turn cleaning is simple.
get some rubbing alcohol and soak the top lid and top grind area for a few min and while soaking grab an old toothbrush and clean the grinders teeth, side wall inside and out and do not loose the nylon ring, ya loose that get a new grinder, after ya remove the gunk on the parts rinse off in hott water and let dry b4 use. I got a small mason jar I use for the rubbing alcohol so i am not buying rubbing alcohol every other week.
