MDF® has reinvented the classic Babinski reflex hammer design by adding a heavy duty telescoping handle that extends beyond an overall length of 15 inches. Expertly handcrafted for precision and patient comfort, the silicone bumper can be used in both perpendicular and parallel positions, with the patented Spring-loaded Locking System (SLS) securely locking the mallet into place. A hidden built-in brush at the end of the handle can be easily removed to elicit cutaneous reflexes. All MDF® reflex hammers are backed by our Lifetime Warranty.
