Guppie 2 CRKT wrote a new chapter in the book of multitool design with the Guppie. It is based upon an adjustable wrench mechanism with a large carabiner built into the frame. Quality of construction is excellent, despite the reputation sometimes associated with products made in China.

Guppie 1


Unlike regular adjustable wrenches, the wrench jaws on the Guppie are serrated, like plier jaws. There are fine serrations out to the tip, with a coarse serrated gripping area in near the base. Maximum jaw opening is 3/4 inch (19mm).


The intricate frame of the Guppie is cast and cut from a single piece of stainless steel. Finish is bead blast stainless, with a few components given a deep black finish for contrast.

Utilizing a spring loaded gate, a large cut-out portion of the frame functions as a carabiner. (Note that the carabiner is not intended for weight-bearing applications.)

Blades and Tools

The knife blade on the Guppie is 2 inch long (51mm). It features a drop point profile, with a large thumbhole for one hand opening.

Locking Mechanism

The knife blade does not lock open.

Other Features

In the base of the Guppie there is a hex bit receptacle with a magnetic bit holder. (Magnet seems rather weak.)

A removable plastic bit carrier is positioned along one side of the tool. It has stations for four 1/4 inch hex bits. In one end there is a high intensity LED light, with slide switch. The bit carrier uses two strong magnets and two close-fitting plastic pegs to remain attached to the side of the Guppie.

A pocket clip is secured to the side opposite the bit carrier.

A lip on one jaw of the carabiner can be used to open bottle caps and metal jar lids.


No sheath is included with the Guppie.


  • Length = 3-5/8" (92mm)
  • Width = 2" (51mm)
  • Thickness, with bit carrier installed = 1" (25mm)
  • Weight = 5.3 oz (150g)


In 2009 an all black version of the Guppie will be available.


Introduced at the 2007 Shot Show, became generally available later that summer.
The Li'l Guppie is basically a scaled down version.
