I've been using the same 4 muzzy heads since 2005.
I think they've killed 9 deer, although it's probably just one head that has actually killed all the deer.
I noticed, while resharpening them recently, that 3 of the heads still look brand new and one shows some wear.
I must be a creature of habit, using the same arrow all the time.

I hate making a good first impression. There’s no way I can keep that shit up.
