Unfortunately, my favorite rulers are no longer made.
Fingerguard rulers made by a gal up in Maine. I try to buy up as many as I can when I see them online (Ebay, etc.). I know there is a product out there that will replicate this ruler, but I haven't tried it as yet. (The ruler has a raised strip 1" in from the cutting end to prevent your fingers from getting cut by your rotary cutter). Great idea, wish she hadn't stopped producing them.
