In this section, Don Manuel is trying to offer precise instructions on how to hold the sword. He uses the positions of the fingernails to do this – up, down, inside etc. In doing this, he follows the tradition of earlier destreza rapier texts – Carranza/Pacheco etc. The hand position most commonly illustrated by De Brea is with the fingernails turned inside. Again, this coincides with the earlier texts and so we can assume that this is initial starting position and hand position will then vary according to the circumstances of the fight.
To hold a foil, one needs to learn six hand positions: fingernails turned inside, fingernails turned outwards, fingernails turned down, fingernails turned up, fingernails halfway between turned up and outwards and fingernails turned halfway between turned down and out. These are the ways that the hand has to perform defensive and offensive actions – always remembering that the inside line of a man is his chest and the outside line is his back.
 Fingernails turned inwards: corresponds to high quart
Fingernails turned outwards: corresponds to seconde
Fingernails turned down: corresponds to tierce
Fingernails turned up: corresponds to quart
Fingernails halfway between turned up and outwards: corresponds to low quart
Fingernails turned halfway between turned down and in: corresponds to low tierce
