Putty Knife Protector

Looking for a better tool for removing prints from the 3D printer, I thought a medium sized flexible putty knife that was sharpened might be good if used bevel-down. I purchased a 1 1/4" Warner putty knife and ground a bevel on one side. It works great on non-tape surfaces, but it's crazy sharp and I'm nervous transporting it. So I thought I'd print a cover for it.
