Every knife that I ship is made by me, and each knife is different because they are made by hand. An oyster knife starts as a piece of RWL34 or Damasteel. I use these materials because they are very rust resistant. The steel is (waterjet) cut and hardened to a hard and springy state where it is perfect for opening oysters.
I then ground the bevels and glue the handles. The material I use is different per model, but it is always a beautiful hardwood that gives a knife character. The final steps are making a case, etching the makers mark and quality control. It takes 8 to 20 hours to make an oyster knife from scratch. I show this in the video below:
