T313.  Iron sukashi tsuba with shakudo plugs.  7.8 x 7.9 x .5 cm.  The nakago hitsu-ana is 1.2 x 2.8 cm.  This is a very heavy tsuba with a great tsuchime surface.  To me this looks like abstract modern art.  The large plugged sukashi is big enough to have been a working hitsu-ana but the smaller one is too small and has been decorative from the start.  The extra sukashi strips next to the plugs are a nice touch.  The small plug is scratched on one side but all else about the tsuba is in excellent condition.  $275.
