Thank you Tom,
Once again, very informative post
. The Dagger unfortunately is no longer with me but I shall try to answer some of your queries out of memory.
The 'Habiki' is made of wood and fits the Blade very well. It also seemed to be a good tight fit with the Handle...I didnt try to force it in for fear of damaging the Handle but am sure could be re-fitted by someone more qualified than I am.
The Blade was thin (by thin, I mean that it was not thick
if you know what I mean). It was fatter in the middle as you said. The edge seemed quite fine and the tip was sharp too. But, it did not seem to be tempered...(my knowledge on Japanese Weapons is very limited, but I have seen a traditional Katana with a good temper and this was nothing close to that, of course the comparison may not be moot here).
Best Regards,
Karni
