At first I thought, "I have one of those but mine's an OXO Good Grips." However, I see that
MarilynFL's Messermeister has a serrated edge. I didn't know anyone made a serrated edge so will definitely have to add a Messermeister to my gadget drawer. I learn something new every day at this site!
Thanks, MariynFL, and also Curious1 for posting the pic link.
