I have found this knife today, and i would like someone to help me with identifying. It is 18cm total length, horn handle and carbon steel nickel covered.
It has stamp on the blade SISA. Also i need some help with sharpening it. I tried with sandpaper on mousepad, 800, 1000, 1200, 1500, 2000, 2500 and finished with 3000, and
also leather strop, was trying to get convex edge, but no success. Thanks in advance
