Lead Inlay KoTosho Tsuba



This is an extremely rare example of a lead inlaid tosho sukashi tsuba. The sukashi is a very delicately done rendition which looks like a crawling praying mantis, however, another interpretation is that it is of sasa leaves with dew drops. The sukashi is inlaid completely with lead that is actually just thicker than the iron surface. The inlay method is different than the usual method used for plugging hitsu ana, being more artistic, polished and tapered. There are some old abrasions in places to the lead, however, it maintains a very nice dark patina. The surface of the iron maintains a very nice dark patina, and original surface file marks are even visible in places. There is one point on the rim of the tsuba which has what appears to be a divet. The fact that this tsuba is lavishly adorned with lead implies that it was produced before lead became a military commodity following contact with the Portuguese and the introduction of firearms. When this tsuba was made, lead was still a prestige metal, the color of this lead also implies that it may have something else mixed in with it or that it was not completely refined. Many archeological sites across Japan have yielded many lead tosogu from the Muromachi period, however, with the introduction of firearms, lead was reused for musket balls.  Many early pieces with lead plugs had them removed so the lead could be reused.  The survival of such a piece in such  original condition is unusual.
