The most common grains worldwide are wheat and rice. I have no wheat home but I tried with 2 different varieties of rice. 8 grains of one variety gives 2.5cm and the other gives 1.5cm. So the average is 2cm exactly. My measurements are in kitchen rice without the husk. If today’s rice is more fat than the medieval, we counter balance with the lack of the husk (what am I saying
????).
Conclusion: Superior swords are 1 meter long, inferior are 50cm and the middle ones are in between these sizes. Very good!
My swords smell mostly oils but I am not sure how the blood of a tortoise (dallak pusht) does smell.
