Big Brother Boldness. A Tribute to Heritage, Reimagined for Heavy-Duty EDC.

Expanding upon the celebrated original, the Biblio XL amplifies everything users love about GiantMouse's cornerstone folder. Larger and more commanding, this upgraded variant swaps the standoffs for a titanium backspacer, boosting strength and style while improving overall rigidity. The premium Vanadis 4E tool steel blade, treated with a sleek PVD coating, combines wear resistance with high hardness (~62 HRC), ready to conquer cutting tasks with precision.

Inspired by the creative ambiance of the Biblio bar in Brooklyn, where GiantMouse was born, this knife captures both the brand’s origin story and its dedication to craftsmanship. The Blue G10 scales, ergonomic contours, and liner lock mechanism deliver a comfortable yet secure grip. Built in Maniago, Italy, the Biblio XL blends design, performance, and narrative into a blade that means business.
