The process of making tools from waste circular saw blades

The concrete steps of using waste circular saw blades as cutting tools are divided into the following three steps:

1. First, select the saw blade with appropriate size, and then take out the prepared handle. When the saw blade and the handle are installed together, it is necessary to pay attention to the choice of sharp tools here, which can effectively avoid sawtooth debris and do not need too much polishing in the future process. . If the handle is made of wood, cut the wood in half vertically, put a part of the saw blade in the middle, and then nail the wood together and fix it. If the handle is made of iron, it can only be welded directly.

When we have a simple shape, we will make a tip for the knife. Grind the front end of the saw blade into a right triangle with a grinder. After molding, it can be polished again from the side, which is smoother and easier to use. ) of course, you can grind it if you like acute angles, but it's a bit troublesome. If there is no grinder, you can slowly grind it by hand with rough grindstones and the like.

3. At this time, it is necessary to make blades. You need to remove all the serrations first, and then polish the blade. You can choose to grind off all the serrations with a grinder, or you can cut them off with a cutter, and then use a grinder to roughly open the edges and a grindstone to finely open the edges. The cutting edge is simple, and it only needs to be polished repeatedly for a few minutes with a grinding wheel.
