Fiskars Momentum – Blade Sharpening Tips

Fiskars Momentum – Blade sharpening:  Regarding sharpening the blades or the the Fiskars Momentum Push Reel Mower. With further investigation & testing, we are now reversing our opinion re: blade “sharpening”, saying “Fiskars does not recommend sharpening the Momentum™ reel mower. The equipment and processes used in home sharpening kits, and even by many professional sharpeners, will likely not be able to achieve the strict tolerances required to maintain the non-contact nature of the cutting system. In the unlikely event that the blades on a heavily used Momentum™ manual reel mower begin to show signs of dulling, Fiskars recommends backlapping to restore the blade edges.”  To “backlap” the Momentum™ reel mower, an abrasive lapping compound is applied to the blades with a brush and the reel is spun backwards via a special hand crank until the blades are smooth and sharpness is restored. While existing backlapping kits for reel mowers can be modified to work with Momentum™ push reel lawn mower, Fiskars is developing a custom kit that will be available in late 2011 or early 2012. The Fiskars kit will include a hand crank designed specifically for the Momentum™ mower, a lapping compound ideally suited for the Momentum™ mower’s blades, an application brush and clear, easily followed instructions.
