Arthur Hollands X OSK Leather Tool Bag

OSK × Pastor Arthur Hollands

Limited Edition Leather Tool Roll**

A meeting of craftsmanship, culture, and character.

The OSK × Pastor Arthur Hollands Leather Tool Roll is a rare collaboration born from shared values of authenticity, precision, and respect for the craft. Designed in partnership with Pastor Arthur Hollands of Japan, this piece reflects the spirit of custom motorcycle culture—where every detail matters, and nothing is accidental.

Crafted entirely by hand using Chromexcel® leather from Horween, this tool roll carries a depth of texture and richness that only decades of tanning expertise can produce. The leather will soften, darken, and develop a unique patina over time—telling the story of every mile and every repair.

The interior features 22 individual tool pockets, carefully sized for essential hand tools, along with 3 zippered hollow pockets designed to securely hold screws, nuts, and spark plugs. Every pocket is stitched with purpose, ensuring both protection and accessibility in real-world use.

At the front, a handcrafted sterling silver ornament, created by a local Japanese silversmith, serves as both a functional accent and a symbol of the collaboration—uniting American leather heritage with Japanese artisanal detail.

Whether mounted on a Harley-Davidson or a finely built custom motorcycle, this tool roll is designed not just to carry tools, but to complement the machine itself.

Only 10 pieces have been produced worldwide. Each one is individually handcrafted by master craftsmen, making no two exactly alike.

This is not merchandise.
This is a collector’s tool—built to be used, respected, and passed on.

About Horween Chromexcel® Leather

Chromexcel® is a signature leather developed by the Horween Leather Company, a Chicago-based tannery founded in 1905 and renowned for supplying some of the world’s finest leather for over a century. Produced through a proprietary combination of chrome and vegetable tanning, Chromexcel® is then hot-stuffed with a rich blend of natural oils and waxes.

This process gives the leather its distinctive pull-up effect, deep color variation, and exceptional durability. Over time, Chromexcel® softens while developing a unique patina, reflecting the wear, movement, and environment of its owner. Each hide ages differently, making every piece one of a kind.

Favored by master bootmakers, heritage brands, and craftsmen worldwide, Chromexcel® is prized not only for its strength and longevity, but for the character it gains through use. Chromexcel® — Horween Leather Co.
