What Exactly Is a Paper Cutter?

A paper cutter is any machine with blades that cuts sheets of paper into smaller pieces or shapes – this includes both manual hand-held models and electric machines found in offices. The machine’s blade must always be kept sharp so that it can easily slice through multiple sheets at once without tearing them apart or having them slip out of position.

Unfortunately, manual paper cutters should not be used for cutting more than a small number of sheets because the sharpness of the blade will wear down quickly from all of the force being exerted on it and from making repeated cuts through paper. On the other hand, electric cutters are great for high volume usage but require constant replacement of the blade to keep the machine working well.

7 Reasons Why Sharpen a Paper Cutter:

1. A sharp blade is better for cutting paper because it will not damage the paper as much as a dull blade. Sharp blades cut straight through the paper and leave it intact without tearing or scratching it. Dull blades rip and tear the edges of the paper, sometimes leaving small paper fibers behind on the surface of your work.

2. Sharp blades not only provide a more aesthetically pleasing clean cut, but can also be important if you are cutting paper that will need to be glued into a final product. Sharp blades provide cleaner, more precise cuts and keep your work looking sharp and professional.

3. When you use a dull blade to cut paper, the blade will actually add tiny bits of dirt and debris to the edges of the paper. This will make the cut edges of the paper look brown and white.

4. Poorly sharpened blades cause resistance, making it harder to cut through multiple sheets of paper in a single pass.

5. If you use a dull blade to cut your paper, it will leave a ragged edge because the blade will curl the paper as it passes through. This will create a rough cut.

6. Sharp blades also reduce tearing, which can occur when you cut lightweight papers such as newsprint or tissue paper with dull blades. Sharp blades will gently slice right through these types of papers, reducing the potential to tear them along their length.

7. Dull blades can damage delicate papers such as onion skin paper or tissue paper by creating pilling on the surface after repeated passes through the blade.

8 Steps To Follow How to Sharpen Paper Cutter at Home 

Step 1: Collect The Necessary Tools

To get the job done, you will need some newspaper or old magazine to remove excess debris that may damage your working surface. Also, make sure there is enough space for you to work on. Finally, getting all the necessary tools and materials together will save time later.

Step 2: Unplug The Cutter

Be sure to unplug the cutter from the power supply before you begin. This is for your own safety as well as preventing any damage to the cutter.

Step 3: Remove The Blade

When the cutter has been unplugged, you have to remove the blade from its holding. Once it is off, take a close look at the sharpness of the blade. If you think it should be sharper or done more often, what follows will show you how to do so.

Step 4: Mark the Area That You Will Sharpen

You have to mark the area that you will be sharpening. Doing so helps to sharpen the specific part of the blade, which produces consistent results every time. Sharpening both parts may cause an imbalance, which can damage your blade in no time.

Step 5: Find the Angle and Mark-It

You have to find the angle that the blade was originally sharpened at. You can do this by using a protractor or just using your eye because it may be already stamped around the side of the blade housing where you remove it from. Once you find it, mark both sides with tape not to forget what angle you are using.

Step 6: Sharpen the Blade

You have to have your sharpening tools ready for this, so be sure to have them nearby. You can use a whetstone or diamond stone, or fine sandpaper—the choice is yours depending on what you feel most comfortable with.

If you choose a finer paper, make sure it is wet to form a paste. If not, use it dry to start with. Next, rub the blade against the paper until you see metal shavings in your newspaper or magazine. You may have to rub it in multiple directions to achieve an even edge all over the blade.

Step 7: Polish the Blade

Polishing does not actually sharpen the blade, but it makes it look good. You can use any metal polish on the blade to make it shine, or you can also use toothpaste with baking soda, which are abrasive materials that will remove corrosion and rust from the blade.

Step 8: Put Everything Back Together

Once you have finished sharpening and polishing the blade, you can put everything back together and test it out. You may have to adjust the angle of the blade is not cutting straight across.

Note: Remember that sharpening or replacing a paper cutter are two different things altogether. Sharpening only adjusts the angle of the blade while replacing replaces an entire blade altogether when it cannot be sharpened anymore.
