BioCurve® Hammers feature a patented 19° bent handle that fits the contours of the hand while positioning the wrist in neutral. The BioCurve handle distributes force to large muscle groups, reducing worker fatigue. High-carbon steel heads with oval-shaped hickory wood handles for strength, long life, and comfort. Pick the style to suit the job.
When the hand moves out of a neutral position, as it does when gripping a straight-handle tool, the carpal tunnel is compressed and grip strength is diminished. Damage to the carpal tunnel can result. In extreme cases, workers report incapacitating pain, hand weakness, lack of hand control, and sensitivity in the fingers. When grasping Biocurve®,'s slightly bent handle, the carpal tunnel remains open.
