ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a Hunting Knife having a simple replaceable blade edges.
The advantages of such a Hunting Knife are readily employed in hunting, fishing, butcheries and even household use.
The replaceable cutting edge of the blade avoids the necessity for knife sharpening, a major task especially while hunting and fishing. The replaced dull blade edge may be sharpened at a more convenient time or disposed.
The Hunting Knife may easily be adopted for other uses such as butcheries, kitchen knife, etc.
2. Prior Art
U.S. Pat. No. 2,109,108 relates to knives and has a replaceable blade which is separable from a knife handle and go replaced with another blade.
U.S. Pat. No. 2,507,019 presents a reversible blade which utility is the performance of a double duty, stabbing and skinning.
U.S. Pat. No. 2,671,962 relates to hand tools, specifically construction tools, wherein a tool member such as a knife or saw blade is readily separated from its handle.
U.S. Pat. No. 4,180,909 introduces a knife with a tension rod insertable into an opening extending through a handle for retaining a replaceable blade at the other end of the handle.
U.S. Pat. No. 4,813,143 deals with a handle suitable for knives and other implements which permits a blade to be adjustable in length.
SUMMARY OF THE INVENTION
The petitioner introduces a blade holder to which replaceable blades may be mounted. The preferred embodiment here shown introduces a folding blade holder. Permanent blade holders may also be used for applications other than hunting and field use.
The replaceable blade holder (
11
) may be that used in butcheries, kitchens, cooking knifes and other applications where different knives are used.
Another immediately obvious advantage of the use of one basic knife with different attachments in the economy of space and simplicity of replacement of parts rather than whole knives which is economical where a large number of knives are used as, for example, in commercial butcheries, large restaurant butcheries, etc.
Foremost, however, are the advantages provided for a hunter in the field who may easily replace the blade when it becomes dull or contaminated and store it for later cleaning and sharpening.
These are the unique advantages of the present invention. There has been no previous introduction of such an application from the prior art.
The thrust of the invention also deals with its two main features:
a) Ease of replaceability of the blade as replaceable blade;
b) Compatibility and ease of handling by the hunter vis-a-vis, the foldability of the knife for easy storage and instant production for use.
Foremost, however; are the advantages provided for a hunter in the field who may easily replace the blade when it becomes dull or contaminated and store it for later cleaning and sharpening.
These are the unique advantages of the present invention. There has been no previous introduction of such an application from the prior art.
The blade is part of the blade section and not the whole blade as in the other inventions.
Further, the knife edge also may be used in a non-folding knife.
