All paper cutters use a wide guillotine-style blade to drive through the stack of paper, no matter the thickness or width of the cut. These blades can also be used for cutting into a nylon cutting stick on the bed of a cutter. This stick of cutting makes sure the blade can go through each paper.
When the blade becomes dull because of long usage, the paper starts to be pushed instead of sliced and the cut will not be acceptable. This can be solved by sharpening the blade. However, the blade cannot be sharpened on the cutter but has to be removed first.
In order to remove the blade, low the stick and stop it in the down position. There is a setting for a paper cutter to do this procedure. You should remove the blade from the outside to the middle; left, right, and repeat until the center bolt remains. For facts, go here.
When this is completed, give back the guillotine to its up position and the blade will come off. Several blades are large, so they require two handles that are screwed into corresponding sockets in the face of the blade to remove.
There are different models and make for paper cutter blades. The most significant thing that makes the difference between blades is the blade angle. It is the cutting edge angle to the blade face. The sharpening must be suitable to the specific blade angel for the model of the cutting machine from this homepage.
The performance of cutting is affected by the steepness of the pit. It also affects the motor power in driving the mechanism of the blade. Hence you need to check the specifications for the appropriate blade angle of cutter.
You can also sharpen a cutter blade manually. You can sharpen it with a file, grinder or even a stone. But, sharpening it manually can lead to an inaccurate blade angle. The best way to sharpen it is taking it to a professional blade sharpening shop. For more info about cutting sticks, visit https://en.wikipedia.org/wiki/Knife.
If you want to install the blade back to the cutter stick, then you simply reverse the process of removing it. Just bring the guillotine down, insert the blade, and attach the bolts from the inside to the edges. But, you should check first to make sure that the blade is level. It should also contact the cutting stick from side to side at the same time. If it cannot touch the cutting stick, then you need to replace it with a new blade.
