Featured in this lot we have an inlayed box containing Japanese katana blade cleaning and maintenance tools. The cleaning tools consist of a brass mekugi hammer, uchiko ball with powder, choji sword oil, cloth patches for oil, kozuka handle, and additional copper and wood material. The hammer shows brass construction with knurling across the middle and a removeable awl the is treaded into the top of the hammer head. The uchiko ball is filled with uchiko powder which is made from ground up polishing stones and is used to maintain the surface of the blade. The choji sword oil with its original box and a glass bottle with some of the oil remaining. The cloth patches are used for spreading the oil and come in a plastic box with a griffon design on the front. Finally the kit comes with a brass kozuka handle showing a depiction of two peacocks along with copper and bamboo parts used for fixing or replacing guard spacers and mekugi pins. The parts come in a carved wood box with inlayed brass and ivory across the top and sides. The piece shows good condition overall with some light wear due to use. The kit weighs 1lb 4oz.
