Agree with other comments that this is one of the few places to get proper geometric explanations of what these conical lapping discs do to clipper blades. Most sharpeners don't understand what they are doing. It's just magic to them.
Thanks for posting this. I do not sharpen clipper blades as part of my services, but now, finally, I understand the concept behind this sharpening process. Very well done !
My family will be so relieved. Thank you I have refused to cut my hair until I figure this out and understand the proper way to sharpen my clipper blades. My family is starting to get concerned about me. I have tried so many different ways for so long. I'm starting to sport a big fluffy head of hair like something out of '70s classic rock.
Thank you, thank you, thank you. I am an engineer, machinist, dog and horse owner. This is first I understand how a clipper blade is truly supposed to be sharpened!
Great explanation of the hollow ground shape used to sharpen grommet blades .. in a perfect sharpening the leading and trailing surfaces would/should be parallel and the oval shape shown in many videos is actually due to het and over pressure on the blades. . The hollow grinding simply make the contact area on the blade/cutter and rear guides a lot smaller. Based on the videos posted I see most professional pet sharpeners using very course grit ( 180-240 grit ) to sharpen the blades and cutters. Knife sharpeners regularly go to 3,000 grit and many even go to 10,000 grit to obtain the sharpest most consistent edge possible. I am at a loss to understand why a flat grind to higher grits (3000+) would not achieve even better cutting results. Can you explain why the hollow grind is actually required vs a flat grind ?
Friction. More area of contact creates more heat. Plus, when you get hair between the two pieces, it will push the blade apart. The tiny hollow grind allows the oscillating movement to push the hair away and not cause the blade to gap. Sure, there is a relief in most blade systems but it all begins right at the tip. If the whole tip is flat, it takes that much more travel time to get rid of the hair. Adding a hollow grind creates an ever increasing gap which facilitates self-cleaning. Clear as mud? ;-)
sir i am subscriber of your channel. I watch your videos regularly from India. The lapping disk you use. It is better to give some details about how much diomond grit is in this disk. Better yet can I get this disk on amazon. Give the link if you get it.
supongo que existe una fórmula para calcularlo. Porque según entendí en la primer parte, el ángulo no es el mismo en cualquier diámetro de disco. O estoy perdido, o sería bueno saber cómo calcular dicha medida.
Has anyone used the flat side of that plate with hook and loop sandpaper somehow to sharpen scissors? I'm looking into buying an arm with convex clamp to try
Excellent, perfect explanation, my question would be : Why?, why does the blade need that curvature? . what is the science there?,,, after thinking for some time, I think I know,, That is to emulate the geometry of a pair of scissors, their blades are not straight, they are concave, they touch in a single point all the way to the tip. when in action.
Thank you, thank you, thank you. This is the only video I have found that accurately explains blade geometry.

Mesmo sem entender uma palavra suas explicações usando sinais ficaram muito claras!
Me ajudou muito, como sei que a outros também.
Só posso ser grato!

Thanks for the explanation. I now know why I haven’t been able to sharpen my dog clipper blades on my wet or diamond stones. Thank you.

Really interesting Thx, do you think a hollow grind is needed on all clipper blades like A5 snap ons or is a flat lap good enough?
Interesting... I always thought those were flat-lapped like a CPU heatsink.
Thanks for the vid.

What is the angle cut into the disc radius relative to the axis of the center hole, that would be information that is helpful.

Iam from India please tell me which taper disc?
Which digree?
Good job, I'm a fan!
Thank you very much, a real Engineer.
perfect excellent explanation
perfect video. now i understand the technic
Has anyone used the flat side of that plate with hook and loop sandpaper somehow to sharpen scissors? I'm looking into buying an arm with convex clamp to try
Were can i get the sharpening plate or disic

Hola cómo están, y alguien pudo averiguar cuál es la fórmula para encontrar el ángulo que lleva cada disco o plato?
Thank you... excellent explanation
Hola enviando discos para Argentina?
great video thank you!!
I needed disic
A el video es super interesante lo que pasa es que no lo entiendo.
