How to Sharpen a Paper Cutter Blade?
Paper cutters are used in offices and home craft rooms. These leverage powered devices allow you to make smooth, precision cuts to shape all sizes and weights of paper. A sharp blade is essential for your paper cutter to work properly. Sharpening the blade on your guillotine style paper cutter will take some time, the proper equipment, a bit of know how and a lot of practice. Once the technique is mastered, your paper cutter will be as sharp as a razor and cutting uniform edges.
- Close the paper cutter's bladed swing arm. Hold the handle of the swing arm firmly in the down position with one hand while you remove the retaining bolt from the hinge side of the arm with your adjustable wrench. Grasp the frame of the arm and pull the swing arm free of the main body of the cutter. Be careful of the blade when handling the swing arm.
- Flip the swing arm so that the blade is facing upward and the beveled side of the blade is facing you. Slide the frame down into the bench mounted vise and close the vise so that its jaws grip the frame of the arm without obstructing the blade.
- Stand so that you are facing the end of the swing arm. Turn on your rotary tool's "Power" switch and bring it to full speed. Hold the tool at a 22-degree angle to the blade. Touch the spinning bit against the far end of the beveled side of the blade and pull it towards you while you maintain the same pressure and angle. Repeat this stroke until the edge of the blade is smooth and sharp.
- Wipe the blade clean with a dry rag to get rid of any debris from sharpening. Pour a tablespoon of vegetable oil onto a rag and wipe the blade to protect the metal from rust. Set the blade into place on the main body of the cutter. Slide the retaining bolt through the arm and into the cutter. Twist the bolt as tight as possible by hand. Snug the retaining bolt with your adjustable wrench. Lift the swing arm, insert a piece of paper into the cutter and press the swing arm down to test out your blade.
Tips & Warnings
- There are many varieties and styles of paper cutters. The guillotine style cutter is detailed here, but the blade sharpening process on any cutter is much the same. Remove the blade, clamp it down and sharpen it with your rotary tool at a 22 degree angle. See your manufacturer's recommendations for specific removal instructions.
- Many rotary cutter devices are self-sharpening and other types of cutters have fixed blades and cannot be disassembled. These cutters cannot be sharpened. Again, refer to your manufacturer's recommendations for specific guidelines concerning your paper cutter.
- Always wear gloves and use caution when working with a blade.
- Safety glasses and a good pair of work gloves are a necessity when working with a rotary tool.
How to Sharpen a Rotary Cutter Blade?
If you have a large tool collection, there's a good chance that several of those tools use rotary blades, those flat round discs of metal with alternating beveled teeth all around. Circular saws, table saws, miter saws and others use essentially the same principle of spinning that blade forward through the wood. Like any blade, rotary blades get dull with use. If you're doing trimwork or other jobs that require precision cuts, you'll want to buy a new blade. But if you just need to sharpen a saw to finish some rip-out or rough cutting, take 10 minutes and do it yourself. (This plan isn't recommended for carbide blades, as the metal is likely to be harder than your file.)
- Remove the blade from your saw according to the instructions. Clamp the blade into the vise on your workbench.
- Put a crayon mark on any one of the teeth.
- Note which of the teeth have their beveled edges facing you as you look at the flat side of the blade and which are turned away from you. They will be alternating. Set the tip of your file against one of the teeth in which the bevel is facing you, at or near the crayon mark. Stroke the file along the bevel, climbing toward the tip and back down. Give it three or four strokes.
- Skip a tooth and go to the next tooth on which the beveled side is facing you. Repeat the process. Continue around the saw, taking it out of the vise and rotating it as necessary to get to the bottom teeth. Continue until you come back to your crayon mark, so you know you've gone all the way around the blade.
- Flip the blade around in the vise so you're looking at the other flat side. Repeat the whole process, starting with marking a tooth with the crayon and again sharpening the teeth with the bevels facing you. Put your blade back on the saw.
Tips & Warnings
- Make sure your saw is unplugged when you remove or reinstall the blade.
