Are you talking about clippers, like the ones at the barber shop? Try "andis", they range from $14.00 - $400.00. Im sure you could find a blade with larger teeth. Maybe pet groomers blades? Anyways heres a cheap one:
-This one is a 14 piece set and only $17.00:
-Here is a seperate universal attachment that will hook right up to a vacuum. (for those multi pound harvest's).
