Hammers are multifunctional devices. Originally these hammers were used for percussion instruments, but in the 1870’s Wilhelm Erb saw the possibilities of using these hammers to test the knee reflex. Every since, hammers have been a tool to test reflexes.
At Dutch Antiques we sometimes have these very special products available.
