The Bear Trap necklace. For when you need a little help landing that burly, bearded, beer-guzzlin', F-150-nuzzlin', buck-poppin', wood-choppin', bar-brawl-squelchin', Star-Spangled-Banner-belchin' homosexual in Carhartts and plaid.
The trap measures only 2.5 x 5 cm, but the hinged jaws really open and close. So even if they fail to snag you that grizzly, they will indubitably succeed in downing the smack on the next jackass who asks you to pull his finger. Chain is 65mm long, and necklace is available in oxydized black or sterling silver.
