Gerber Cool Tool


Cool Tool, stainlessThe Cool Tool was one of the very first multi-purpose bicycle tools. Based on an adjustable wrench, it offered the user a wide range of capabilities in one convenient device. A few early models were lightweight titanium and made in the USA. The majority were made from stainless steel and imported from Taiwan. Only later did Gerber acquire the rights to produce and sell the Cool Tool.

Wrench

An adjustable wrench forms the basis of the Cool Tool. Its jaws open up to 11/16" (18mm) The jaws themselves are particularly narrow, allowing them to reach areas inaccessable to most wrenches.

The "handle" of the wrench is the frame of a bicycle chain tool. When used in conjunction with the threaded pusher rod, it allows the user to break down and reassemble individual links in the chain.

  • Stainless models: finish is cast matte. The name "COOL TOOL" appears at one end. The numbers (916) 893-3079 and the words patented Taiwan are cast into the handle.

  • Titanium models: finish is cast matte. The name "COOL TOOL" appears at one end. MADE IN USA is cast into the wrench head. The numbers (916) 893-3079 are on the opposite side.
  • Large double-ended socket. One side is 15mm, the other side is 14mm. Two slots in the side of the socket allow it to be turned with the adjustable wrench.
  • Double ended hex driver. One end is 8mm, the other end is 10mm. A hex hole through the center allows it to be turned with the 6mm wrench.
  • 6mm wrench. One end is 6mm hex, the other end is a phillips screwdriver.
  • 5mm wrench. One end is 5mm hex, the other end is a 4mm wrench.
