The hilt is everything that isn’t the blade and consists of the grip (the part you wrap your hand around), the pommel (the generally enlarged base that keeps your hand from slipping off the bottom end), the quillon (the cross piece that keeps the hand from moving forward onto the blade), and on some swords and sabers, the knuckle or “D” guard.
Yep, and it’s the guard, not the hilt, that looks like a half swastika. (Almost slipped there. Typed swastinka but caught myself).
