Maybe it's not very helpful to most of you but here is my setup anyway - my access to professional studio equipment helps a lot

The camera is a field camera Sinar p2 with 90mm or 150mm lenses by Rodenstock or Schneider and a 80MP digital back from PhaseOne.
For lighting I use a flash with two slim-lights and a board from the top that has a matte-silver cover. It is mounted on an extra stand so I can move it up and down and adjust the angle. The slim-lights reveal textures and create sharp outlines and the cardboard produces an even reflex on the blade with a nice hotspot. Sometimes I add an extra spotlight for even more texture or color.









Maybe that helps a little bit and I’ll happily answer any questions
