Thanks Iain

,
not having a tri-fullered blade to hand, I was not certain as to the usual dimensions of such a blade. Regretfully, I sold my Takouba (3 fullers) a few years ago

so had nothing 'to go on' )
Nevertheless, having the dimensions of the imported blades could prove useful and may give a good indication when compared to native made blades that mimic European blades. It would also be interesting to see if some of the Kattara were supplied with the same 'pattern' of blade.
I also wondered whether such blades were supplied ready to hilt and just needed sharpening....or if the blades were more 'raw' which allowed the locals to profile the blade to have either a double or single edge...and would also be, I assume, cheaper to purchase.
All the best
