MDF® has re-invented the original Babinski hammer by adding a patented Spring-loaded Locking System (SLS) to securely lock the articulating head into place while in use. MDF also added a robust telescoping handle that is wider and thicker to withstand the force of repeated striking. This patented and newly designed hammer enables practitioner to strike with greater precision and less effort while also providing increased patient comfort. The MDF Telescoping Babinski 2.0 Hammer is meticulously handcrafted with attention to detail and extreme quality standards, and it also comes with a lifetime warranty.
