I used an XI Demon bow for 12 years. Had the same string on it for 11 years. (broken strands and all)
I have some judo points that are probably older than several users of this forum.
I have a bitzenburger jig that I've had since the 80's that I still use to fletch my arrows.
I also have two Browning Nomad recurves that are fairly 'old'.
I have some original Treebark camo too.
