Apparently Tormek is starting a new series... here's the first one:
Thanks for posting this, CB.
As much as I like the depth of the online classes, I can see also see the value in these short, one question videos. I look forward to the rest of the series.

PS Well done, Sebastien!
Interesting. I can see where, if it works, "it doesn't get any easier than that"...
And I agree, a short, specific point video like that is great.
... but I've always just used the marker method to match the existing angles - and they sometimes differ between the top and bottom blades. That is what I call it doesn't get any easier than...

I agree. In fact there might be different angles for the thumb blade and the finger blade. Therefore the marker method is my choice as well. A good explanation can be found here https://www.sharpeninghandbook.info/GT-Scissors-General.html
Where does the 10 degrees come from? Is he assuming the scissor blade is a 10-degree wedge?
I also prefer the marker method.
Not only does the angle differ on each of the blades, I have sharpened scissors where the angle changes along the length of the blade. In that case I just use the angle at the center of the blade. But I'm not sharpening any special-use scissors, just kitchen scissors and scissors for cutting paper or cloth.
My daughter-in-law is a hair dresser. She won't let me near her very expensive scissors and I don't blame her. I've seen videos of how those are sharpened and a Tormek is not up to that task.
I believe the 10 degree angle is from the jig that holds the scissors. If you look at it from the side, you'll notice that the clamps and base are not completely parallel.
On a side note, I had recently sharpened a pair of hairdressing scissors. They were some Japanese brand with that clamshell-shaped blade profile.
All I knew was that the hairdresser had set it aside because it had gotten dull, and it cost her about $200 for that tiny pair of scissors (barely 15cm in length)
I scrutinised it under my digital microscope, looking for areas with a consistent scratch pattern (to know how it was sharpened) Then I just pressed the inner side of each blade against the side of my SJ-250 for about 2-3 minutes, cleaned it up and reassembled it.
She said it was as sharp as brand new, but was not using it as frequently as before. (It was a shop rental/leasing issue, not the scissor sharpness)
