Found a Less Expensive Substitute!
Thanks for the safety tip--Excellent idea to keep your fingers away from sharp rotary blades. Unfortunately $70 for a blade guard is a bit too expensive for me. I decided to look for something less pricey. I tried my local Joann's, but they had sold out their stock of the suction-cupped ruler holder. I recalled seeing something similar at Menards. They had a suction grip handle meant for use in a bath/shower, but it was a bit too large. I looked further and found a suction-cupped clear plastic towel bar that is the perfect size for my 4 x18" ruler and works on my 6 x 24" ruler, too. It looks like the Joann's suction-cup quilt ruler hande, but a bit smaller and clear so the ruler marks show under it. It appears to be fairly sturdy too. I posted a picture of it attached to my ruler along with the package so you can see what it looks like. This will keep rotary cutter blades away from my fingers and the price was right only, $3.88! These nifty little suction-cupped towel bars are in the shower section at Menards. I would imagine these are also carried by other stores too!
