Thanks to reader Nikka who sent this in!
Alexander McQueen's knuckle duster clutch retailed for $1595 at Net-A-Porter but is no longer available.
Nikka found a great alternative from Religion, and it retails for £50.00, which is a little over $70. Click here if you're interested in purchasing this look 4 less. *Note on 10/23/10: I believe this clutch is sold out now - it disappeared off the website late yesterday*
