Mark the spine of an indivual blade for quick identification

[parnass]

I used a red Sharpie (felt tip marker) to mark the spine of the main knife blade in a multitool so I can find it more quickly.  Does anyone else do the same?

A more permanent solution would be to use a triangle file or a Dremel rotary tool cutting disk to make a few notches in spine.

I have really appreciated the new Leathermans where they mill a thumb ramp into the serrated OH blades.  I usually don't have an issue locating the specific tools on a multi other than that, but that';s probably from years of experience with SAKs.  Often times if I loan a SAK to someone the first question they ask is which one is the screwdriver/blade/saw or whatever they are looking for, so I am certain lots of people out there could benefit from a color code.  Maybe red for sharps, green for benign tools like magnifiers, blue for can/bottle openers?
