Thanks everyone for the feedback.  Would an authentic example have (gulp) a threaded tang?   
 
Also, the singular finger rest (can it rightly be called a pas d'ane given its position?) seems a very practical feature for a single edged weapon as it allows for easy indexing.  A double edged blade can have a more symmetrical layout.  Is this a fair thought?
