A loop is formed by a bow having across one side a strip or blade. The bow has flexure and memory. The flexure and memory of the bow are imparted to the strip, enabling the strip to be either taut or loose, depending on the pressure exerted by the operator upon the bow. The bow is held and manipulated by the operator with the thumb and finger. The strip is positioned under tension. A holder for the device allows additional variability in the angle of attack of the strip, and facilitates quick and easy interchange of the strips. A holder avoids insertion of fingers far back in the mouth, where working space is limited.
