Birthday present for boyfriend?

My boyfriend of over a year is turning 18 next month :) but I can't decide on the perfect gift. I know I'm gonna wrap up a blindfold and make him put it on and I'll come back into the room with some sexy lingerie on for him. But I wanna get him something more than just sex. He's a farmer and loves to hunt. Very outdoorsy and says he doesn't want anything for his birthday. All ideas are accepted and appreciated! Thanks! :)
