What does “Full Custom” mean?

Each full custom piece is handcrafted by me from the ground up. Only the heat treatment is performed externally for precision reasons. From the raw flat steel to the finished knife, each piece undergoes an intensive, artisanal process in which every detail is meticulously crafted. This distinguishes it from "production folders" like the Neutron Star, which are mass-produced by machine.

With Full Customs, I can naturally express my creativity and creative urges. After every day in the workshop, I come home tired and dirty, but with a deep sense of satisfaction that I've only experienced through knife making. For the first time, I'm making this knife category publicly available and I'm confident every buyer will be thrilled.
