How to string a recurve bow 
Purchase a bow stringer. 
This cheap tool is 100% necessary to string your recurve bow without damaging the limbs. Choose one designed for a recurve bow (not a longbow), and intended for your bow's length and draw weight.
Confirm that the ends of the stringer fit snugly over your bow's limb tips. Some sources recommend the " pocket and saddle " design for recurve bows, but " double pocket " stringers are also common.
