Hunting pocket knives sharpeners were first made of any smooth rock that was handy.  The rocks worked pretty well after hours of stroking the blade.  Use the knife once and sharpen again.  The compounds of iron and other elements weren't hard enough to hold the edge for longer than one use.  Soon hunters would find a favorite rock that would sharpen in a lot less time.  As the steel became tougher and held an edge longer, a need arose for a better product to sharpen more quickly and efficiently.  Along came the predecessor to the modern knife sharpener - the file.

Today's hunting pocket knives sharpeners were  carried by hunters, to assist with cleaning game or what ever other use that might be found in a hunting camp.  Sharpeners have become so very sophisticated and efficient that sharpening the new age of steel to a fine honed edge can take but a matter of minutes. The workmanship and efficiency of today's sharpeners are available in many different shapes and sizes, from being so small to carry in one's pocket or larger and made to be left in camp. No hunter should be left without an excellent hunting pocket knife sharpener.
