I just put 2" white masking tape on the back of the ruler 
Be very careful cutting with aluminum rulers.
They are softer than the steel blade and the knife bites into them.
Once the knife is up on the ruler and there aint no stopping it.
Not even your fingers.
When I learned this…
I went back down to my project and the little bit of my finger was still there…
Steel rulers and triangles rule
I don't remember the brand of ruling pen I have.
I tossed the box and put it in my compass set (remember those?).
The pen was a going away gift when I got canned from my first job.
IIRC, it costed about a third of my week's salary at that time.
No one else use it
