Abstract
Disclosed is a blade grinder comprising a blade holder that is mounted so as to be rotatable about a horizontal shaft which is mounted so as to be rotatable about a vertical axis, thus allowing the blade to be optimally adjusted relative to a grinding disk. The grinding disk can preferably be vertically and horizontally moved using spindles. This creates a simple design allowing a lawnmower blade to be ground in a fully automatic manner.
