I would also add that often even perfectly sharpened blades won't cut, due to problems with the clipper malfunctioning, or being improperly set up or misadjusted. So, if you removed the hollow when you sharpened the blades, they probably won't cut. And each time a blade is sharpened, you only remove perhaps a few thousands. The sharpening process for hair clipper blades includes many steps, requiring a fair amount of skill and careful consideration. What I have described is how blade manufacturers sharpen new blades, as well as any knowledgeable sharpener. This hollow allows the two blades to cut together, and also maked the edges a bit thinner/sharper. If you open up any scissors and examine the inside of the blades (the surfaces facing each other when the scissors is closed), you'll see this hollow grind. And you might be interested to know that all scissors also have a hollow grind. Most clipper blades are sharpened with this hollow grind. The reason for the dome shape is to produce a hollow grind on the blade surface being sharpened. I have seen just about every clipper blade problem you. It helps if you visualize a dome-shaped plate, but one which is tall rather than flat, and you imagine applying a flat blade to the dome, you'll see how the blade ends up with a hollow grind. My name is Rick Pletcher and I have been in business sharpening clipper blades for over 21 years. It's higher near the center of the plate. So, if you lay a straightedge radially on the plate, you should see that the plate is flat, but the straightedge isn't quite horizontal. The difference in height between the center and the peripehery varies, depending on who manufactured the plate, and what type blades are to be sharpened on that particular plate. Unbolt That Bad Boy Up Once you have them disconnected, you’ll want to give both blades a thorough rinse to remove any dirt or debris. There should be 2 blades in total: a small one and a large one. You’ll need a screwdriver to unbolt the blades from the clipper. The sharpening plate is ever-so-slightly domed, meaning that it is slightly higher in the center, compared to out at the periphery. Step 1: Detach The 2 Blades From The Clipper. The blade(s) are held such that the teeth are oriented radially. They are sharpenened on a horizontal spinning, flat-appearing plate, which has an abrasive mixture of grit and lard oil applied to the plate. I have a sharpening business, and although I don't do clipper blades myself, I do know how they are done, using horizontal flat honing/sharpening machines.
