Flat grinding an L-6 blank to the center scribe line along the cutting edge of the blade. After all the grinding is done, the blades are heat treated. This is all done in-house at Siggma, so the high quality can be controlled.




When the heat treating is completed and tested, the blades are ready for assembly. After the handle is afixed and shaped, the knife goes through a series of progressively finer sanding processes.



Once satisfied with the ultrafine sanding, the knife is ready to have the mirror polishing done. Every 440-C (stainless steel) knife is polished to a high luster mirror finish. All Siggma knives have only the natural "finish". They are polished, no coatings, paints, lacquers, or other "finishes" are used on Siggma Knives.
