Chicago Electric makes this inexpensive chainsaw sharpener that sells for $35 at Harbor Freight. Sure, the quality of tools purchased from Harbor Freight can be suspect, but how can you screw up a chainsaw sharpener?
The 0.5″ to 0.8″ capacity vice on this sharpener adjusts from 0-35° to the right or left. The 115V, 0.75A ball bearing motor spins the 4-1/4″-diameter by 1/8″-thick grinding wheel at 4,200 RPM. A safety guard covers most of the wheel, exposing only the section that comes into contact with the chain. You can either hold the sharpener in a vise or mount it to your bench or garage wall.
The question before us today: Can buying this cheap chainsaw sharpener be a better deal than doing it the old-fashioned way with a guide and a file? Or does doing it yourself even make sense when you can pay $10 for a professional to do it? Let us know what you think in comments.
