i finally got what i consider the ultimate grinder yesterday. it features a hand crank for a better grip and some extra power. the herb can only be ground so small before it falls through the perfect sized holes into the screen chamber, and the clear window on top lets the user know when this has been achieved. then finally we have the keif catcher which comes with a handy little scraping tool. it was 35 bucks which is a bit crooked, but if it gives me even 8 months of the joy i have experienced in just the first day it will be money well spent. never again will loss of friction caused by residue be of concern to me, and never again will i over or under grind my herb again. it's some no name so it will probably break in a month but it's really everything i ever wanted in a grinder.
