A Siebe Gorman 'Non magnetic' divers knife, marked to the blade 'SIEBE GORMAN & CO *'.
The star on the blade denotes the type being non magnetic.
Double edged steel blade with brass collar (split to one edge) and I think ebonised handle and brass sheath marked 'NON MAGNETIC' and underlined. The legends 'TINY' and a 'Z' have also been added. With canvas belt and loop as shown.
Any of our knives can be polished up before being sent out, please ask! The choice is personal, some people like the old patina so we don't tend to polish them all up.
