My name is Jakub Wieczorkiewicz and I’ve been designing and making custom knives since 2012. Poltergeist Works is my brand and my custom knife workshop located in Poland. I use the highest quality powder metalurgy steels, tool steel, GRADE 5 titanium aswell as G10 and carbon fiber composite to create unique custom tactical edged tools. In the recent years I’ve started collaborating with the best knife manufacturers that helped me introduce my designs to a larger knife audience.
