The Hammer Wrench is the latest tool added to the upper mid performance line. This is the first pearlized cover in this line since the Epidemic. The Wrench adds a pearlized version of Grand Theft III Reactive from the Jet Black Taboo and a modified version of the Mirror Plane asymmetric core.

This combination gave the Wrench a strong skid/flip reaction on our medium test pattern. The cover gave us more length than the Ratchet with a sharper move at the breakpoint. Our two...

The pearlized cover on this ball offers a much more angular breakpoint than the Ratchet and Brick. Hammer fans who want to see a big back end movement will like the Wrench.
Length

EBI has found the right combination of underlying grit and polish to make their shells less sensitive to oil. The Wrench’s 2000 and Powerhouse Factory Finish still gives the ball enough bite to keep from throwing it through the pin curtain.
Back End
(1-20)
17.5
The length and torque at the breakpoint sets the ball up for a big back end reaction. It easily falls into the skid/flip category of ball reaction.
Total Hook
(1-100)

The shiny box finish keeps the total hook rating down. The move at the back end more than makes up for covering less overall boards. For us, the total hook was still plenty for our test patterns.

Strengths: We are not exaggerating the back end move this ball makes when it exits the pattern. The skid/snap reaction is the Wrench’s biggest strength.

Weaknesses: Only oil patterns that are both heavy and long will keep the Wrench from being used. Pull out a Brick or Taboo Deep Purple for those types of conditions.

Overall Summary: The Wrench is a great addition to the upper mid price line. The Wrench is the ball to go to when the Brick, Ratchet, or Taboo are starting to hook too much, too early.
