William king of Scotland 1165-1214
Habeat, equum, habergeon, capitum e ferro, et Cultellum qui dicitur dagger
Let him have a horse, a habergeon, a helm of iron, and a knife called a dagger.
Count of Toulouse in 1152
Si quis aliqem hominem malum, quem Cultellarium dicimus, cum cultellis euntem nocte cause furandi occiderit, nullum damnum patiatur propter hoc.
If any one kills any bad man, whom we call a Cutler, going with knives for the purpose of stealing at night, he shall suffer no loss for this.
and probably the best as far as detailing what these pieces looked like.
Rigord’s descript of troops at the battle of Bouvines 1213
Habebant cultellos langos
They had long knives
Graciles, triacumines quolibet acumine indifferentur secantes a cuspide usque and manbrium, quibus utebantur pro gladius.
Slender, triacumines (a sharp three sided herb leaf)* were indifferently cut by any point from the tip to the hilt, which they used as swords.
*best translation I could gather from some serious Latin folk
So with these extensive detailed descriptions we can say they had long triangular blade that were sharp from tip to guard.
The pieces we crafted for our customer certainly is that and more. It would be an excellent weapon in a fight and one that I think makes a exceptional blade wether one calls it a dagger or a sword.
