Lignorim Prime Model

The Prime model is unique through its optimal ergonomic shape with a cross-section of 1.00" x 1.25" (25 x 30 mm).  The concave section on the upper side acts as a guide for the thumb and the result is a more controlled grip, and maximum contact.   The unique design of the Prime model offers both energy savings with its enlarged contact surface and also gives the wrist additional stability.  The Prime model is intended for average to larger hand sizes.
