Most of the SAKs don't have ruler and specially the ones I own.
Ruler is important for multi purposes.
So I was wondering have people figured out a way to "stamp" or "carve" a ruler on their SAK(s)?
Looking at my Spirit, I see that one can put markings up to 2.5" and 6 cm on the saw, as the saw teeth follow a pattern with the inch and cm markings on the ruler. The ruler length wouldn't be big but it's better then nothing. It can certainly help if you want to stamp something(nail, pin, tape, etc.) at a precise point w/o the help of some other tool.
