That's a blade grinder. You can also get coffee grinders that use a
burr.
With those you adjust the grind by the position of the burr. They're
harder to find and more expensive.
Thanks, John... the whole grinder thing makes more sense to me now...
I'll have to look into a couple of those (1 for wife, 1 for shop) since
my wife
is a coffee "gourmet" and I'm a "red can" sorta guy.. *g*
The easy tactic is to buy a pound of el cheapo coffee beans at the grocery
store and use their grinder set to 'espresso' for extra fine grounds.
