There is also a modern terminology of "1707" as an angel number with basically the same interpretation. I personally do not think the number a year date as in manufacturing. I also suggest that it is probably not 18th century, but made to appear and exude ancient origin and mystery. I might suggest that the "J" motif on the blade is a short hand symbol for the Veve for Papa Legba. Papa legba being depicted as an old man with a cane/crutch, like the number people in the know would understand the coding. I uploaded the Veve for Papa Legba and the cane is on the right hand side.
