Colorado School of Mines

Colorado School of Mines is one of the most well known and prestigious engineering universities in the world. Founded in 1874, the college quickly gained notoriety for its hands-on approach to the study of natural sciences. I began my time at Mines in the fall of 2021 in pursuit of a mechanical engineering degree. A unique component of the School of Mines is their metallurgy and material science program. This program is one of the best and features a highly unusual class as an elective for MME students: bladesmithing, the art and science of making knives. The class teaches the metallurgy involved in making high-carbon steel blades and combines that with time in the machine shop, allowing students to craft two unique blades of their own. As a freshman with experience in the subject, I took great interest in the program and was soon hired as a teaching assistant. My joy in the class also gave me a love for teaching and connecting with students. The experience allowed me to bring creativity to a college apparently devoid of artistic programs. 

In my third year at Mines, I received a once-in-a-lifetime opportunity. My graduation year happened to fall on the 150th anniversary of the university’s creation. In honor of this celebration, the president of the school commissioned me to build a ceremonial broadsword—a relic of the school’s prestige and its historic foundations. I agreed, with one small condition: to be knighted with that very sword by the president upon my graduation. He agreed, and I set to work. What followed was one of the most difficult and rewarding projects I have ever completed.

Thousand of Layers

I started the build during a truly rough patch in my life. The spring semester of my junior year, I was looking to get ahead and enrolled in 23 credit hours, nearly double the number needed to be considered a full-time student. That January, I lost two family members in a tragic and preventable fire. In February, the other side of my family was split by a legal dispute that was soon buried in courts and corruption. In March, I was robbed in Costa Rica while night-time skinny dipping and literally lost the clothes off my back as well as my passport and valuables. In April, my academic standing dropped dramatically while  I also faced ridicule and scorn while on a group project that turned from fantasy to nightmare. In May, things started to look up when I entered a relationship with a beautiful woman for whom I cared deeply. In June, she dumped me. Coincidentally, it was  my birthday. I found myself alone, with no one except God and my dog: all of my friends had gone home for the summer. Confronting the stagnant silence of a run-down rental house in a heat wave and no air conditioning, truly this was my lowest point.  My only coping skill was to channel my sorrows into my work. I stacked up ten pounds of high carbon steel and welded together a rough billet. The next day, I lit the forge, heated the billet until it was white and sparkling—and then wailed on it with my hammer with all of my strength and fury. With the help of a hydraulic press, I next drew the billet out into a long bar. Using a band saw, I cut this bar into equal sized chunks, stacked them tall, and welded them together. This resulted in a piece that looked much like my original billet, but hidden inside, several layers  told the story of my work. Pattern welded steel, often known as Damascus, is created when two alloys are bonded together and folded, twisted, or manipulated. When etched, acid “eats” each  alloy  differently, exposing a patterned record of the forging process. For the next six weeks, all I did was weld, forge, cut, and stack this billet over and over. With each layer, I grieved the tragedies that had befallen me. Each spark and hammer blow was a defiant shout at God. But he sat by patiently. All told, I didn’t need to fold the billet as many times as I did—but after almost two months, I finally found a moment of peace that I could only reach through the heat and the fire of the forge. 

At one point I stopped, checked my tally, and found that my billet weighed only two pounds but contained 5,312 layers of folded steel! I had made peace with God and decided to put my hammer down. With the forging finished, I hardened the steel: heating it to its critical temperature and quenching it rapidly in a bath of oil. This shock can destroy a blade, as any cracks hidden beneath the surface quickly propagate, ruining weeks of work. However, if the steel survives the shock, it maintains a higher energy state, with a fine grain that is hard and resilient to impact. Thankfully, my blade survived the shock. And in many ways, so had I. 

After the quench, the rest of the process passed by with a pleasant steadiness that I knew meant it was time to coast. Grinding, sanding, and filing soon turned into fluting, setting, and polishing. The really fun part of the project turned out to be twisting sterling silver wire that I inlayed into exotic blue mango wood. As its crown, I cast a silver bezel, in which I  set a stunning tanzanite gemstone. 

By September, my deadline neared and several sleepless nights counted down to a finale. My last coat of oil was still drying when I raced to campus to unveil my masterpiece. A huge crowd of several thousand attended the celebration on the day of the school’s anniversary. I arrived at the last minute, in my work clothes, covered in soot and burn marks. In a feverish state, I found myself holding a microphone and giving a hastily prepared speech to the crowd before me. I was exhausted and snapped to consciousness when the crowd erupted into applause—it seemed my speech was finished. I was told I spoke well and unveiled the sword confidently, although I have little memory of this. After hundreds of hours of labor and thousands of folds, my sword was finished. I was at peace.

Triumph

The following spring I found myself in a similar state of ecstatic fever  during my graduation ceremony: I was on track to pass all of my classes and finish strong. But before doing so,  I sustained an injury during routine forging. A small crack hidden in a piece of hardened steel fractured explosively when I struck it with a hammer, and a steel shard shot into the back of my hand. In a case like this, a small piece of hardened steel can retain most of the kinetic energy imparted by a hammer. From my degree I learned that energy is always transferred, not created or destroyed, and that kinetic energy is exponentially influenced by velocity but only by a half of its mass (KE=(1/2)mV^2). What this means is that the energy from the mass of the hammer was traded into the velocity of the shrapnel, which hit me at the speed of a small-caliber rifle. It was the week of final exams and graduation. Nevertheless, I weathered three surgeries to finally extract the piece. The final surgery occurred on the morning of my commencement ceremony and left me in a lucid dream of fentanyl and pain killers as I donned my cap and gown. Nothing quite felt real as I stepped onto that stage. The lights were blinding, and the crowd sat patiently before me. In my one good hand I brandished my broadsword in all of its power and beauty. In what felt like slow motion, I raised it high above my head in triumph. The crowd exploded. I locked eyes with the president of the school, gently handed him the blade, and dropped to one knee before him. With my head bowed, I felt the gentle tap of the blade on each shoulder. I had been granted knighthood! I rose with vigor, a feeling akin to baptism. Indeed, it was a baptism by fire. But I had survived. I received my diploma and smiled until my face went numb, giddy with the accomplishment of  my time at Mines. To my knowledge, I am the only person to ever graduate from Mines with the unofficial title, “Sir” Engineer.
