Our traditional strings are hand-made from start to finish. We use a completely unique building technique when it comes to our traditional strings. We lay them up by hand and hand serve each end loop. Each string undergoes a pre-stretching process to eliminate any shoot-in time and stretching of the string. We use BCY B55, a very popular string material. It is 100% polyester, similar to Dacron, but with better durability and very low stretch. BCY B55 is primarily used for recurve bows, but is also used on older compound crossbows and traditional bows without reinforced limb tips. All end loops are 3D or Halo and the center servings are made from Halo for ease of shooting off fingers.
