Your equipment should perform every time you shoot and a bow square is the first step towards ensuring a correct setup time and time again. Easy to use and a must have for every archer. The Flex bow square Multi is a sturdy tool that can be used as wrench for most nocks and 2, 3 or 4 blades broadheads to safely install them. Next to that, the three blades wrench can be used to check the correct fletching of arrows with three vanes. Special plastic is used because of its strength and flexibility and the rounded corners will not damage your string or serving. The Flex bow square Multi is available in a full range of colours.
