Already got a Metal Cross Boomerang. You can barely see it coming out from behind my head, as it's strapped to the same strap that the Dagger is on, only from the backside.
So on my backside, I am bearing a Cross.
As for the whip, I've held a real long-chain one with a flail at the end, but it would've been uncomfortable to carry that around, whereas the leather one neatly wraps in a circle and can be hung on either the Sword Pommel or around my arm.
Trust me, the look was Sold. Got a lot of compliments, that day.
