Pauli breaks down his new passivation process for sandblasted stainless steel blades, covering why blasting creates rust problems and how a citric acid bath fixes it. He also shares a cheap DIY version any maker can try at home. Albert talks through the painful story of a hook hollow ground chef knife with solid copper cladding that delaminated right before the finish line. The crew also gets into custom screws, carbide end mills, and the discovery that Austria is sitting on one of Europe's largest tungsten deposits which leads to some questionable field trip planning.

Next week: award-winning Austrian bladesmith Marco Gadavics joins the show.
