These protective collars/hats are often used when using bearpaw speed points. They are placed below the point (prior to gluing) and sit neatly on the end of the shaft. They reinforce the tip of the arrow and reduced the number of damaged shafts from hitting stones etc.. which is par for the course in field archery. It's also possible to use them just below the nock to massively reduce the chance of another arrow damaging the shaft when sat in a target.
