Our laminated grips were inspired by the propeller on a WW I Fokker E. V/DVIII monoplane at the United States Army Aviation Museum at Fort Rucker, AL. Please visit and support this fantastic facility...it is a great resource of our heritage and history. The lamination produces a very strong product and is visually striking...we start with presentation grade materials and painstakingly match the grain when they are assembled, giving a visually seamless appearance. We select for nice color combinations, using only the natural colors of the woods. If you have ideas for other combinations, just give us a shout. This set showcases the gorgeous colors of the Purpleheart and Curly Maple. A hand-rubbed satin finish provides years of low maintenance beauty and protection.
