"We offer five different models of Herdim peg shapers, each with a range of peg hole sizes, allowing them to cover a large spectrum of peg sizes. The brass bodies are fitted with double-sided blades which display high cutting performance and excellent edge life. Resharpening the blades is not recommended due to the differential hardening of the cutting edges. The soft plastic case provides a comfortable, non-slip grip. All peg shapers come with instructions for use and a hexagonal key for adjusting the blade. Taper 1/30, diameter 8 x 6.3; 8.5 x 6.8; 9 x 7.3; 9.5 x 7.8 mm, length 50 mm. Standard Shaper for violin/viola suitable for 4/4 & 3/4 violin and standard viola. For use with #5063 Violin Peg Reamer.
