[Jim McDougall]

Thanks guys, it is amazing how much 'fine tuning' is necessary in some discussions which are indeed figuratively 'narrow' in themselves as are the certain elements which are in question. I do think however that additional clarification must be made, as Jens notes, a hand may be slim...but not necessarily 'narrow' (=long?).

So we are thinking of the depth of the hand rather than the length.
Equally, by narrow we must consider the width of the hand, as the katar grips are enclosed at either side. My hand is over 4" wide, far too wide for a 2.5" to 3" enclosure.

With the tulwar and the khanda, the hand is around the grip without as notable an enclosure (unless the distance between guard and is very narrow). I noticed a reference in reading that one figure in an Indian court was 'large' (larger?) but that his weapons were indeed made larger in accord.

Does this mean he was of 'regular' size as opposed to 'smaller' (in stature) Indian men, or that he was even notably larger than even the normal size men of the period overall ?

I find it rather surprising to think that the author, Mr. Daehnhardt, would not care about a term he used in description, but perhaps considered such' hair splitting' irrelevant. He undoubtedly presumed those inclined to read his book were peers who were able to discern what he meant.
It would seem that the note toward the Portuguese preferring their own weapons over the Indian talwar because the grips on them were too small, made the specification obvious.
It would seem that the 'peculiarity' of smaller size in 'many' Indian men in certain ethnographic groups is fairly well known, and applies not to physiological or especially anatomical particulars, but to general physique which includes hands.

As for the preference of the Portuguese to their own weapons, it was not just the grip sizes of talwars* but that the Portuguese were Iberian, and had a deep affinity for their rapiers (and other swords) which were designed for their own forms of swordsmanship. A talwar was hardly designed for sword to sword combat (fencing).

* unsure of the spelling, some references say 'tulwar' rather than 'talwar'.
