Hoping to add
Fias, a benshira weapon designed to fit over the finger tips, so maybe priced per set of 5, 10 or per 'nail'?
And also the
Atani, a Svefra weapon designed as a scarf that is barbed with blades, or blunted weights.
Lastly, are pencils a possibility in Mizahar, technology/magic wise? If it makes a difference, the earliest pencils I found were from 1630, but instead of an octagon/hexagon with the color/graphite inside, they were rectangular with one side open, where the inside part could be more easily slid in, I guess.
