A Smooth, Solid Sharpener

The Magna-Matic 8100 Standard Lawn Mower Blade Sharpener has an incredibly rigid design that delivers smooth, solid grinding, and makes sharpening conventional flat mower blades comfortable and easy. The Magna-Matic 8100 makes it easy to maintain a 30 degree cutting edge angle without complicated adjustments or time consuming tools. A single crank raises and lowers the wheel, and it stays where you adjust it. Simply lower the wheel until it almost touches the worktable, and it will cut a 30 degree angle (+ or - 0.5 degrees) over the life of its 7" diameter grinding wheel. No other sharpener can promise that.
