An Old Masai Seme....I'm not so certain

[katana]

The Seme has arrived ...and is better than I thought Hand forged with a nice tempered blade which is still quite sharp (no evidence of recent honing either) The 'forte' is 6 sided (almost diamond cross section with two of the opposing 'angles' that are flattened 5mm) The blade 'thickness' then gradually decreases as the blade width widens. The last 40% of the blade it's thickness is decreased significantly (as the blade is widened)

The wire used in the handle is cable which has been covered in leather (which follows the 'contours' of the wire below. The tang is slightly exposed at the end.

Although the handle is useable, I can't help feeling that this was likely used two handed by gripping the forte.
There is a nice patina to the blade and although the handle seems to have had a repair...it looks as if this was done quite awhile ago.

Would late 19th C early 20th C be likely?

Please any info / comments greatly appreciated, thankyou
