Wet wheel grinders were designed for sharpening, making them the best tool to use for sharpening garden shredder blades. Since these have a built-in vice, along with a guide that will help you to maintain a consistent angle, wet wheel grinders will give you the most accurate finish. We know of plenty of people who have happily resharpened the blades. Just be aware, Bosch say not to do it. If your blades are dual-edged and both sides are blunt, flip them over and do the same on the other side. 2. Sharpening Garden Shredder Blades with a Wet Wheel Grinder The Bosch comes with a “double sided, laser-cut precision blade that delivers approximately 7 times more cutting power than conventional blade shredders”.

However, the blades are not meant to be re-sharpened. As you can see – the Bosch blade is quite chunky. To stop vibration the blade needs to stay balanced. Sharpening, unless done professionally, is likely to unbalance the blade. Using an impact shredder with unbalanced blades create vibration and increased noise levels.
