Hammer Black Widow Assassin Bowling Ball Review

Hammer Black Widow Assassin

Review By Chad R. Of Mobile Mechanic Hawaii

As an avid fan of the sport, I’ve had the opportunity to try several bowling balls. I’ve owned half a dozen balls in the last 3 years and spent over a thousand dollars on them but I have yet to find one that is as good as my Hammer Black Widow Assassin bowling ball.

Hammer Bowling, a company that is well known for producing the toughest bowling balls around, just released the Black Widow Assassin. It’s the latest under the Black Widow series and let me tell you, this thing has one heck of a BITE.

If you’re looking to buy a new ball and you’re thinking of getting the Black Widow Assassin, take a few minutes to read this review so you’ll learn more about its specs, features and drawbacks.

Product Specs

Hammer Black Widow Assassin Bowling Ball Review

Many players consider the Black Widow Assassin as the best bowling ball they’ve ever owned. To find out if it’s the best option for you, let’s start by listing down its specs:

  • Coverstock: NBT solid
  • 12-16 lb weights
  • Pin Length: 3-4
  • Core Type: Asymmetrical / High Mass Bias Gas Mask
  • Color: Purple/Red/Navy
  • Reaction: Length with Sharp Backend
  • 500/500/500/1000 Abralon® with Powerhouse™ Factory Finish Polish
  • Best Lane Condition: Medium – Heavy Oil
  • Hook Potential: High


Hammer Bowling has a complete line of high performance bowling balls and the Black Widow Assassin is no exception. Take a look at its advantages:

  • This ball has a nice sharp angle to the pocket and a powerful skip flip movement.
  • The Gas Mask Core provides an excellent grip and ensures great pin action.
  • It stores plenty of energy, enabling it to pack a punch when it crushes the pins.
  • It moves smoothly and swiftly down the lane.
  • It looks very intimidating and will certainly attract attention at the bowling alley.
  • This ball is hard hitting and makes replicating shots easy.


But of course, it’s not perfect. For one, you probably won’t appreciate the heavy oil patterns and its reaction on heavily oiled lanes isn’t great. You may need to move several boards to the right while aiming at the same arrow, or you can use another ball if you plan to play in a heavily oiled lane.

What Do Other Customers Say About This Ball?

The Hammer Black Widow Assassin reviews on Amazon are really impressive. In fact, it has a perfect 5-star rating with over a dozen reviews. Customers who left a review on the website are very happy with this ball and in fact, many have said that their game scores improved when they started using the Black Widow Assassin.


It’s not exactly easy to find a bowling ball that not only fits you and your style, but also has a great motion every time it rolls down the lane. Many people consider it a favorite because it’s very dependable – it will really continue rolling through the pin deck. It’s a safe and strong ball that is just as versatile as the original Black Widow. If you’re serious about bowling, this ball is a no brainer.
