The man we know today as Turkana Boy was almost certainly smiling when he picked up his new stone knife, gently rubbed his finger along the freshly flinted edge, and uttered a satisfied, “Ah, yea,” — or its equivalent in the lingo of Homo erectus.
We humans, beginning with our early ancestors, have been using knives for at least 1.5 million years, and you can be assured they were as much a joy to us back then as they are today.

A joy, a necessity, and all but indispensable first-tool for humankind that has never lost its intrinsic appeal.
To hold a sharp, well-made knife in your hands is to slip through the gates of space and time and join the caravan of pre-historic travelers setting out from their African base on an ages-long, dangerous, and uncertain journey to colonize the world.
The knife was an essential tool in making that journey possible.

While the function of a knife is the same today as it was when Turkana Boy sliced a serving of antelope from the animal roasting above the campfire, the material they’re made from has come a ways.
The Guardian 5 shown in the photo above is fashioned from a high-tech steel manufactured by Crucible Industries using a sintered proprietary process known as Crucible Particle Metallurgy which — to greatly simplify the undertaking — atomizes molten alloy into fine powder that is then hot pressed into sheets that are just about ideal for making exceptionally hard and super-sharp knives.
There’s a vast difference between today’s steels and yesteryear’s D2 tool steel from which most of our old knives were made. That said, D2 still makes a fine knife, though short of what you get with CPM-3V, Magnacut, Elmax, Cruwear or some of the other more refined and more pure steels.

The newer steels vastly reduce impurities and non-metallic goop that create weak points in a blade — unwanted hitchhikers such as sulfur, nitrogen, phosphorus and junk metals like tin or lead. With that detritus gone or minimized you’re left with a steel that has increased edge retention, more toughness and greater corrosion resistance.
The Guardian 5 blade, for those who may wish to know, is finished in what Bradford calls “stonewash;” the blade is ground to a sabre edge. The handle is made of G-10, a high-pressure fiberglass laminate of cloth and epoxy resin. It’s exceptionally strong, moisture-resistant and lightweight. Its light green finish is called “ghost.”
G-10 is also low- to zero- maintenance, making it a popular choice for outdoor and heavy-use knives.
You can get the Guardian in other configurations and lengths, from a 3-inch to a 6-inch blade, I believe, along with other blade finishes and a choice of several handle finishes. All ship with a sheath — leather or nylon. Take a look at the company website.
Bradford USA is located in Kent, in Washington State. You won’t go wrong ordering your next knife from them.
