FORGING AND STOCK REMOVAL
An overview
A bed of red-hot coals. A hand-operated bellows feeding precious oxygen into the forge. Ringing blows of a hammer against an anvil, turning and shaping a lump of iron into a useful shape.
Knife and sword making has gotten a lot more attention in the last few decades thanks to popular movies and TV shows like the History Channel’s Forged In Fire. While obviously edited and arranged for maximum dramatic effect (it is supposed to be entertaining, after all!) shows like these give an interesting peek into one of mankind’s oldest methods of toolmaking: the forge. When people think about what knifemakers do, this is what often comes to mind.
However, it's not the only option. More on that in a minute.

Damascus Steel
Folded steel or "Damascus" steel is still created by forging. However, this extremely labor-intensive work has been made a bit easier with a modern invention called a power hammer. A power hammer usually gets its oomph from air pressure, and can come down with a force and precision many times that of a human arm, consistently and without tiring.
Damascus steel itself is made from a combination of different metals including various high carbon or stainless steels, nickel, copper and even titanium, all layered together, heated in a forge to the consistency of warm caramel, hammered flat and then folded in on itself hundreds of times. A skilled artisan can forge Damascus steel to display a remarkably consistent pattern using the contrasts of the various steel layers, everything from roses and raindrops to feathers and barbed wire. We love this gorgeous steel for select pieces from our Rare + Unique collection.

Stock Removal
Time and technology marches on, and steel alloys are only growing more sophisticated as the experts add a little of this, a bit of that to coax more
of what we want from the finished product. Stock removal involves designing and tracing a design on a flat piece of steel (bar or sheet) then cutting it out and finishing it by hand using various small machines.

Our OMAX waterjet slices through leather like a hot knife through butter
Over Dawson Knives’ history we’ve used a variety of machines to cut out our designs, everything from a regular ol’ bandsaw with a beastly blade to a plasma table to, nowadays, a CNC waterjet cutter. For those unfamiliar with what a CNC waterjet is, (me, till about a decade ago) they are computer-controlled machines that use an extremely high pressure (60,000psi) jet of water mixed with pulverized garnet to precisely cut through virtually anything: concrete, steel, aluminum, fingers—itself if you let it. To put this in perspective, the pressure washer you use to clean your driveway operates at about 2,500psi.
Check out this video to see our grouchy 25 y/o OMAX waterjet cutter in action, cutting out the new Armageddon sword!
What comes off the waterjet is what we call a “blank”, the basic silhouette of the knife only. Kind of like those steel gong targets. Next, it goes to Sam, one of our third generation Dawson knifemakers, to be ground. This means using a three-wheel TW-90 machine to give the blade its shape and bevel, then taking it through several levels of abrasives to remove scratches and give the blade a nice even texture. After that it's on to handle shaping, blade finish and sheath making, which I'll cover in another post.

Great blog John! So many people think the only way to make a knife is by forging it …. we have always been in the stock removal camp and can say we learned from the best!!
