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.

I recently placed my first order after finding you on the web while looking for grinding wheels. I am a customer for life. Here's why. My first order was a simple white grinding wheel for a "normal joe's shop". When I received the wrong wheel (150 grit instead of the ordered 100 grit) I called and without hesitation or the 3rd degree another wheel was sent off. No questioning of my integrity, intelligence or honor. Simply "I am sorry, we'll send the correct wheel off immediately..." The right thing was done by a neat guy. I was treated like an adult. Unbelievable in this day and age...proper...and priceless. Price, performance, responsiveness and customer service par excel-lance. 6-Stars! All my sharpening orders, albeit small shop orders, will now be with you. Promote you I will.
