Spring compass from the brand "Kwrak," 17 cm long, robust, black.

This is a sturdy spring compass. The spring compass is a very useful tool for measuring heel length during trimming. The same length between heels on the same hoof, combined with trimming that follows the level of the functional sole, guarantees perfect lateromedial balance. A sheath is included to prevent the tips from damaging your other tools (the sheath is dark blue). Opening width: 75 mm (7.5 cm).
