Kage tsugeru iya uso

From Inga no Kusari wiki

Kage tsugeru iya uso is Neikan Itami's fullbring.

When unreleased it looks like the simple knuckleduster Trench.

When released it continues to look the same, yet the blade is scaled larger and longer (about 2 1/2 ft in length). All three edges are sharpened along with a much more pointed tip.

Fullbring Ability

At this level it isn't much more than an enlarged trench knife; to be used to puncture or stab (as it's intended use), but with edges sharp enough to slice a person (as intended of a sword)

Strengths

Knuckleduster: The Blade of this specific trench knife was very dangerous when used in the trenches in the heat of war. Sharp with the triangular prism blade is quite a disastrous feat when used to stab, puncture and rip through bodily flesh. The Knuckle cover, covered in pyramid spikes for use as a blunt force (and for protection).

Weaknesses

Swordplay: While Louis had taught her simple movements with the knuckleduster, she has real no clue to using it as a sword; especially in this case of the irregular shaped blade.
