This safety arrowhead is designed for Life Action RolePlaying (LARP). It has an absorbent ability and is suitable for shafts of 17/64? (6,75 mm) and 5/16? (7,94 mm).
The arrowhead can easily be attached: treat the shaft with a bit of glue and shove it in the safety arrowhead, until it is fastened tight. If desired the shaft can still be turned. This is not recommended for thicker shafts because it will damage the balance elements.
