I need a source for ferrules for knife handles for Nordic type knife handles. My 2nd problem is with stick tang knife handles. I made a handle with 1 inch pieces of wood alternating between 1/8 inch nickel silver spacers. When I started grinding on the handle the epoxy failed & the pieces of wood & spacer came apart. I redid the handle & again it failed in the same area. The tang didnt go thru the entire knife handle only 1/2 may-do i need to put a dowel or a rod thru the entire handle for structure & for something for the epoxy to stick too.
