Improved Hammer


There are several problems with the hammer (impact device), such as poor shock resistance, which may lead to fatigue and/or stress in the arm and elbow, and to inefficiency. Current invention of the hammer has an even mass distribution for better control and force from the user. It focuses the contact of the hand to a more limited region to allow for better control. The invention also focuses on dampening or decreasing the shock or vibration caused from impact. It uses the laws of physics to improve the performance of common hand tools such as hammers or other hand-held instruments used to strike objects.


  • Transfers more energy at impact (i.e., hits harder)
  • Greatly reduced vibration and shock.
  • May reduce repetitive stress problems in the arm and elbow.
  • Can be applied to sports equipment or other hand instruments used to strike another object.


  • Provides a greater peak force and overall impulse to a target over any other hammers currently on market.
  • Similar in style and feel to existing hammers, but can be uniquely configured if desired.
  • Does not require advanced manufacturing processes for production.
  • Can be made lighter in weight to appeal to new market segments.

Market Potential/Applications

May increase the customer base for all hammers for two reasons: 1) a hammer with the same power can be made more lightweight, thereby diversifying the existing customer base for tools; 2) the possible decrease of fatigue and stress injuries may reduce worker's compensation claims and reduce insurance costs for employees.
