Abstract

ABSTRACT OF THE DISCLOSURE

A multipurpose tool particularly suitable for use by woodsmen comprises a blade portion and an elongate slotted handle portion which fits between guide members secured to the blade portion. When the blade and handle portions are attached together, the tool can be used as a hatchet.
When the blade is detached from the handle portion, it can be gripped in the hand and used for other purposes such as sawing, cutting, bottle or can opening, and wire stripping.

Description

3Sl This invention relates to a multipurpose tool for use, for example, by woodsmen who may require a compact tool suitable for perforrning diverse functions. More particularly, the invention provides a multipurpose tool com-prising a hatchet blade and handle which can be assembled to form a hatchet and which can be detached for use of the hatchet blade fvr other functions.
A multipurpose tool in accordance with the invention comprises a hatchet blade, an elongate handle, and means for releasably securing the handle and blade together for use of the tool as a hatchet, the hatchet blade itself being shaped for gripping in a user's hand when detached from the handle, and being provided, apart from a sharp hatchet edge, also with means for performing at least one further operation when detached from the handle. The blade may, for example, be provided with means for performing one or more of the following operations, namely, sawing, can or bottle Gpening, cutting, or wire stripping.
In one preferred form of the invention, the blade may have spaced handle guides on its opposite surfaces defining a region which may be fitted into the slotted end of an elongate handle for securing the blade and handle together, the blade further including finger openings between said guides and the sharpened edge of the blade, so that when detached from the handle, the blade may be gripped in the hand by inserting the fingers through said openings, with the guides resting comfortably in the palm and together with the finger openings providing a comfortable alternative handle for the blade.
The tool is readily convertible between its different functions by its simple attachment or detachment of the elongate handle, and provides a useful adjunct to a woodsman's equipment.

Figure 5 is a perspective view showing the blade portion of the tool being used as a saw.
A multipurpose woodsmen's tool (Figure 1) comprises a hatchet blade portion 12 and a detachable elongate handle portion 14. With the blade and handle portions assembled as shown in Figure 1, the tool is suit-able for use as a hatchet, but the handle portion may be removed and the blade portion may be used per se for diverse other purposes as will be described.
The blade portion may be formed from conventional hardened steel, and has an arcuate cutting edge 16, the major portion 18 of which forms a smooth hatchet edge, and the minor portion of wbich is formed with sawteeth 20. To the rear edge portion of the blade is a brass guide member 22 of part-circular cross section affixed to the blade by rivets 24. Further brass guide members 26, 28 are fixed by rivets 29 to the blade at a spacing from guide member 22 conforming to the thickness of handle portion 14. The respective guide members have flat facing surfaces 30, 32, 34 respectively.
Handle portion 14 has a slot 36 at one end (Figure 4) enabling the handle portion to slide onto the blade portion between the guide members.
The handle portion then may be tightly secured in place by a hose clip 38 fitting in a groove 40 around the end of the handle portion. When using the tool as a hatchet, the guide members provide support and impact resistance for the handle portion. The handle portion may be provided with a wrist cord 42.
Blade portion 12 further includes four finger openings 44 located between the cutting edge 16 and the guide members, the finger openings and guide members together defining an alternative handle for the blade portion when the elongate handle portion 14 is removed, enabling the blade portion to be gripped in the hand as shown in Figure 5 and the sawteeth 20 used for sawing, with the guide members being received in the user's palm.
Blade portion 12 is further provided with a curved and pointed back ~Z~;~8~

cutting edge 46 at one end of the cutting edge 16, useful, for example, for skinning animals. A can and bottle opening profile 48 at the other end of cutting edge 16, and a sharpened wire stripping notch 50 between the guide members, all of these items being usable when the elongate handle and blade portions are detached.
It will be appreciated from the foregoing that the invention accordingly provides a readily convertible and easily transported multi purpose tool forming a convenient and useful adjunct to a woodsman's equip-ment.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A multipurpose tool comprising a blade portion formed with a cutting edge, a handle portion, and means for releasably supporting the blade and handle portions together for use of the tool to perform a first function employing the cutting edge, the blade portion itself being shaped for gripping in the hand when detached from the handle portion and being formed with means for performing at least one function different from said first function when detached from the handle portion.

2. The invention of Claim 1 wherein the handle portion is of elongate form and is related to the blade portion when secured thereto for use of the cutting edge as a hatchet edge.

3. The invention of Claim 1 wherein the blade portion has pairs of spaced guide members on opposite surfaces, each forming a guideway therebetween, and the elongate handle portion has a slot in one end defining opposed limbs slidably receivable in the respective guideways for securing the handle and blade portions together.

4. The invention of Claim 3 including an encircling clip for said end of the handle portion for tightening same on the blade portion.

5. The invention of Claim 3 including finger openings in the blade portion between the cutting edge and the guide members, the finger openings defining means for gripping the blade portion in the hand when detached from the handle portion, with the guide members being received in the user's palm, whereby the blade portion may be used per se for performing said at least one different function.

6. The invention of Claim 1 wherein the means for performing at least one different function comprises means for performing at least one function from a group comprising sawing, cutting, can or bottle opening, and wire stripping.
