Don't laugh, but the $15.00 4" angle grider from Harbor Freight. Remakably handy for a variety of grinding and rough sharpening jobs. Perfect for sharpening lawn mower blades and garden tools. No, its not a makita, but it's a remarkably well made tool for $15.00. My ebay pencil sharpener. It's a Dixon Enduro No. 20. Far superior to the common Bostons. Sturdy support on both sides of the dual cutter head and an adjustable stop for the perfect point. Scott.
