If ever Batman gets himself hitched, then we are absolutely certain that this will be his ring of choice. The Titanium Utility Ring, crafted from aerospace titanium, like a rose, hides prickly thorns beneath its beauty. Not quite prickly thorns - a straight blade, serrated blade and saw - but you catch our drift. There's even a comb which will come in especially handy for Batman and his hat, well, cowl-hair. $385
