Features: The punch has a flight slot that aligns any flight in place for you to punch a precision slot. The slot allows the shaft springs to actually grip the shafts tighter than when pushed down the shaft by the flight, giving you the most solid dart flight set up for precision scoring.
Directions for use:
1- Place ONLY ONE flight into the slot - do not do more than ONE (this will not work on nylon or Dynastar flights)
2- Punch the hole out of your flight
3- Insert the shaft springs into the hole in the flight
4- Slide the flight and shaft springs onto the shaft together.
