rotary cutting blades
I've used my cutters for the last 20 years. I was wondering what/why there is numbers on them. Are they there to know when to change them exactly or what, I've looked online to no avail.

I think it is from Fiskars . The lines & numbers are along the edge of blade, like a pizza crust. Tried taking a picture but they don't show. Also they have lines in between the numbers like a ruler. I will look on fiskars site

The numbers are on Olfa Blades. Here's the explanation from the olfa site,

08. What do the numbers around the perimeter of the rotary blades mean?The original rotary blade was designed to fit a safety cutter that positioned each section of the rotary blade in a fixed position to be used upon the dulling of the previous section. The numbers represented each of those sections. When OLFA introduced the original rotary cutter in 1979, the numbers became irrelevant, but have been maintained as a sort of historical feature representing the original rotary blade.
