This is a medical reflex hammer for neurological examination made by Streisoutr in France during the late 19th century. The hammer has a beautiful ebony handle which is wonderfully pleasing to the touch and has shallow grooves into which the user's thumb and forefinger should fit. The ebony handle is fitted to the steel head with bone wedges. The head is weighted. The hammer comes in its original fitted case, with purple velvet and silk lining. The metal catch is fully functional. The edge of the rubber tip has slightly dried.
