Black Widow Asassin


It’s the return of a Legend. Black Widows are the most popular series of bowling balls ever produced by Hammer, and now they’re back to bite medium to heavy oil lane conditions.

Black Widow Assassin pairs up two of our most popular components ever - the Widow core and the First Blood coverstock. Sanded in a 1000 grit polished finish, the Black Widow Assassin is one of the most aggressive and continuous hooking balls in the market today.

Combine that signature Widow core motion with today’s coverstocks, and you’ve got one of the TOUGHEST rolling products in the marketplace!
