The Christner Tension-Free is a "one size fits all" model designed to remove tension normally found in the forearm from a pinch style grip. Is held with the middle and ring fingers while the first finger and thumb are floating on the stick. This allows the larger/stronger muscles in your arm to control and hold the baton, taking tension off the forearm and rotator cuff. Bulb size is 1-3/4 x 7/8 inches. Handles are solid hardwood, varnished and buffed to a matte finish for maximum grip. Shafts are solidhardwood, either painted bright white or unvarnished, natural wood. They are of a uniform width for maximum visibility, with a slight taper at the last two inches. Please specify shaft finish and overall baton length when ordering by using the Special Instructions box on the checkout page. The maximum overall length possible is approximately 17 inches from the base of the handle to the tip of the shaft. Most users prefer a baton in the 14 inch range. If a length is not specified, we will build it to 14 inches. Wood species and color of handle may vary from photo. Hand made in Buffalo, NY and assembled to order in Ithaca NY, USA.
