If you are interested in sharpening scissors there are instructions starting on page 13 of the written manual PDF file or at about 7 minutes into part 3 of 4 of the video instructions. There are a total of four parts to the video instructions and the links should be over to the right of this Spyderco video.
These should provide a starting point. I know from watching some scissor sharpening videos about a year ago, that scissor edges can vary. I do not think these videos were posted a year ago*, or whenever it was that I would have liked to find them. [*Uploaded by SpydercoKnives on Nov 22, 2011] I had a very dull or nonfunctional pair of scissors on an used Ambassador and at first I thought I was not going to succeed, but finally had success. I do not remember many particulars, except to carefully examine and then follow the original angle on the scissors. Then, after sharpening the angle, keeping the scissors perfectly flat on the stone, remove any burr on the flat side, as shown in the instructions.
[P.S. The video or media showed in the preview, but I did not see it after posting. Then it showed upon adding this note, so you may or may not see it. In any event the link to the video seems to work fine to take one to the Spyderco Sharpmaker instructional video on YouTube.]
