Damascus is Beautiful
After talking with many people, I realized that most do not understand what damascus steel is. I know that I explained what it is in an earlier post, but it doesn't fully makes sense until you see it. So I decided to put up a picture of my first ever completed damascus project: a 2-inch blade wood carving knife. This was made from a piece that we had to cut o
ff of my larger billet because it wasn't welding right. It only has 17 layers as opposed to my large billet which will have over 500 layers when it is finished. I forged it using a hammer, tongs and anvil (good thing I took that blacksmithing class last year). With the help of my teacher, we ground it down to shape and put in the main bevel. Then I hardened it, which requires heating the knife until its non-magnetic and then quenching it in oil. In our case we used cooking oil, so the forge smelt like popcorn. I then put it in a toaster oven at 425 for two hours (sounds like I'm giving tips for a recipe). The last steps involved sanding the knife using different grits up to 1500 grit and then etching it in acid. I used muriatic acid that my aunt had. The acid eats away the metals at different rates and causes the pattern to emerge. This part was not fun; the fumes coming off the acid were so potent that I could barely breathe. I should have worn a mask over my nose and mouth instead of just using my hand. After the etching, I put on the final edge and presto! a brand new knife ready to be used, well after I get a handle on it.
