Looking for unique groomsmen gift

My male friend will tie the knot next month so i’m scouring the net for the best groomsmen gifts. I want something unique to make it different from the usual gift i give to my male friends.  Sometimes, searching, finding and giving gifts for men can be a real pain. Unlike women’s gifts, gifts for men are much harder to locate. I’ve been thinking what kind of gift to give for him but i’m quite having a hard time. Anyway, i will just ask her fiance i’m sure she can give me a hint on what my friend would like to have in this very special moment in his life.
