Woodhaven Calls Woodhaven Custom Calls Walnut Striker. The idea was to take an existing call and make it even better as well as create a usable sounding board that could be struck repeatedly for that added effect. That is exactly what we set out to do. We are proud to introduce the new Walnut Striker offered along with our other great Predator Calls. This was started with a custom order from a gentleman in Montana many years ago. We received numerous comments from individuals all over the world that this is their go-to call for turkey hunting. They also really like the way it feels in their hands while using it. So for those of you that are into pushing the limits of your calling as well as your gear this is the ticket.
