Poisoned pearls

[Mercenary]

It remains to understand how deep the wounds must be in the case when the pearls or bearings in sabers were located at the base of the blade near the hilt

A bit more. Is it so easy to make grooves in wootz? To put the pearls (!) or bearings inside blade that they can roll there freely? Only to smear it all with poison?
The poison needed when the weapon only scratches, but does not penetrate into the body with the entire length and width of its blade
