The French assault knife inherited traditions from duelists and guard fighters. Its appearance was rough, yet it also had a practical sophistication. The steel blade, often from recycled bayonets, showed the Republic's soldiers' cleverness. The French knife had no extra details. Instead, every line expressed a love for freedom, struggle, and honor. It became an extension of the hopeful French stormtrooper's hand. Even in the muddy trenches, he believed in his ideals' strength.
Initially, the name of the assault knife, POILU by Blade Brothers Knives, echoes the voices of French World War I soldiers. French soldiers often used "Poilu" as an unofficial, yet deeply revered nickname.It embodied the ordinary French WW1 infantryman. Literally, "poilu" means "hairy" or "shaggy." This symbolized, therefore, the male strength, resilience, and endurance of front-line soldiers. So, they lived in harsh trench conditions, consequently, often unable to shave.
On the battlefields of World War I, trenches limited space, making traditional bayonets impractical. Soldiers quickly realized they needed short, reliable knives for daily tasks and close combat. This need spurred the creation of the first trench knives, often converted bayonets, and later, specialized industrial production. The main feature of these knives was their ability to not only cut but also effectively deliver thrusting blows.
The POILU blade perfectly represents this era, embodying the spirit of French stormtroopers. It is a dagger with a unique rhomboid cross-section. This special shape significantly boosts the knife's break strength. Thus, it becomes extremely resistant to lateral loads during a thrusting strike. Grinds, extending straight from the center, provide excellent penetrating properties. Moreover, the dagger leaves a complex wound channel that heals slowly, which was critically important in front-line conditions. The POILU is the embodiment of combat effectiveness and reliability. It met the demands of the harshest trench battles.
