How to make a manual garden shredder

In our gardens we always have organic waste that we can use as compost or to cover the soil with a layer of organic matter. Much of the waste is bulky and handling it can become a problem. To reduce its volume, we can use gasoline or electric grinders, but this is not our goal, because they consume energy to operate. We offer you build a manual shredder for gardens or small orchards that works on the same principle as the shears: Thanks to the multiplying force of a lever, a large cutting force is concentrated at a certain point.
