Slip on hammer accessory. Gives the user more leverage and control for prying. Also works as a soft face attachment for non-marrinig hammering. Save time and money by protecting the work surface when pulling stubborn nails. Fits any size claw hammer. Made of durable Santoprene. Made in America. Works with prybars too! How it works: Place the top of the hammer's head in the bottom groove of the Hammer Helmet. Use the hammer as you normally would to pry a nail and allow the arch shape of the Hammer Helmet to assist the hammer rock in a prying motion. The softness of the Hammer Helmet will prevent the hard hammer's head from damaging the material the nail is stuck in while giving the user more leverage and control.
