There is nothing else to compare with the Amazon. Like its name it is a powerful, forceful and achieves outstanding grinding performance.
It will simultaneously relief grind both faces of the bottom blades returning them to the original manufacturers specification.
Once sharpened the blades will maintain their sharpness just as long if not longer than any other bottom blade grinder.
The Amazon is in a class of its own. It is easy to operate with automatic in feed on both grinding wheels and the enclosed acrylic cabinet contains the noise of operation and any coolant splashes, leaving the operator free to complete other essential workshop tasks.
