About Me

My name is Luke and KajiCustoms is my creative outlet. I've been making knives since I was young; playing around in my Nonno's shop. In the last several years, I have become more serious about it and it has become a large part of my life. I am a chemist by day, but I use my knowledge of material science to fuel my creation by night. I find my peace in my shop.  Therapy is expensive, so I make knives instead. I hope that you enjoy them, but they're more for me than for you, even if you're lucky enough to own one. 

About my knives. I use high carbon tool steel almost exclusively. Most of my knives are W2, 1095, 1075, W1 or old files, rasps and cable steel. Using these steels allows me to create a unique hamon on every piece. Hamon is a Japanese term that means edge "Ha" pattern "mon". It arises from the differential hardening procedure known as "yaki ire". This process yields a knife that combines a high degree of edge hardness with a tough and ductile spine, essentially turning one piece of steel into a composite blade. During this process, which is carried out violently in a water quench, many blades develop stress cracks and 'die in the quench'. Sometimes I can save them, sometimes they are scrap. That's the high risk aspect. On the other hand, if they do survive, there is a high reward aspect. After hours and hours of hand polishing and careful treatments, the most visually stunning pattern is revealed. Personally, I find hamon patterns to be one of the most beautiful art objects known to man. I also consider it the soul of the blade, being created during 'birth' and being completely unique to the blade, just like a soul.
