C.S. Osborne

About C.S. Osborne & Co.

Few tool brands can claim a legacy as deep and unbroken as C.S. Osborne & Co. Founded in 1826 in Newark, New Jersey, the company began as a specialist in tools for harness makers and saddlers — trades that demanded the sharpest edges and most durable construction possible. Nearly two centuries later, C.S. Osborne remains one of the oldest continuously family-owned and operated manufacturing companies in the United States, with eight generations of the Osborne family guiding the business through wars, recessions, and sweeping industrial change.

A Legacy Built on Precision Craftsmanship

What started as a workshop serving the leather and saddle trade quickly grew into something far larger. By the 1880s, C.S. Osborne had become the world's largest manufacturer of tools used to produce horse harnesses, saddles, shoes, and leathercraft goods. The company earned gold medals at the 1876 Philadelphia Centennial, the 1878 Exposition Universelle Internationale in Paris, and the 1879 Sydney International Exhibition — a testament to internationally recognized quality that few tool manufacturers could match.

Over the decades, C.S. Osborne strategically expanded through key acquisitions, adding masonry tools, button dies, hand press machines, awls, and industrial hand-sewing needles to its lineup. Today, the firm's inventory spans over 4,500 different hand tools, the vast majority of which are still manufactured at the company's Harrison, New Jersey factory. As the brand puts it, the goal is to blend nearly two centuries of craftsmanship with modern innovation — and the results speak for themselves.

What C.S. Osborne Makes

C.S. Osborne specializes in industrial, leather, and upholstery tools, with an extended product family that covers everything from cutting and fastening to piercing and setting. Professional upholsterers — including those working in auto upholstery — rely on Osborne's heavy-duty needles, hog ring pliers, tack removers, and shears every day. The brand's utility knives are crafted from high-grade steel, precision-machined or forged, and hand-sharpened to deliver the sharpest edge possible. Their hook and pick sets carry on the company's deep tradition of precision piercing and manipulation tools originally developed for leathercraft. And for workshop versatility, C.S. Osborne also offers bit driver sets that meet the demands of professional tradespeople.

One hallmark of the C.S. Osborne difference is vertical manufacturing control. The company manages the entire production process — from forging raw steel to hand-sharpening the final cutting edge — one tool at a time. This hands-on approach is rare in today's manufacturing landscape and is precisely why professionals trust Osborne tools to perform in demanding, real-world conditions day after day.
