Are they enthusiastic about anything

We're a group of carpenters. One of our young carpenters thinks hammers with fiberglass handles are just wonderful. He keeps trying to talk about them; he even has meetings about them. He invited one of the leading fiberglass hammer handle manufacturers to come speak to us. But we don't understand his fascination with what (to us) is just a useful tool...
