It is just the ferrule and tip (they are all machined from one piece which is a plus) that are titanium. Although I am not a big fan of locking collars to keep the blades in place I would certainly rate this head as a quality one. They are tough, fly great, and come very sharp. Unless something unusual happens the ferrule and tip can be used over and over and buying replacement blades isn't difficult. I have taken deer with them albeit in the 125 grain offering but it isn't really any different than its 100 grain brother.
They are a good head and will perform well with the best the market has to offer.
