THE TOOLS YOUR WORKBENCH IS MISSING

The large, Pro-Grade French Curve set is heavy-duty, and designed for precision work. Most French Curve sets are designed exactly the same - fragile and simplistic. This set is built with enhanced features for the true maker! With the necessary quality for both the professional shop and the weekend hobbyist, this three-piece French curve set delivers uncompromising strength and accuracy for detailed work across leather, pattern-making, and design applications.

WHAT IS A FRENCH CURVE?

French Curves are unique vintage tools from the late 1800s used in art, drafting, woodworking, and textiles. They are designed to create a virtually infinite amount of natural, non-circular curves that perfectly round templates or compasses simply cannot make. Use them to cut smooth arcs or to draw organic, ergonomic shapes such as necklines, pocket flaps, curved pieces, etc. French Curves are highly-effective, indispensable tools for any maker.

PROWDLY ENGINEERED FOR DURABILITY AND PRECISION

Made in-house in the USA
Three complementary sizes: 18", 10", and 6.5" that scale from large sweeping arcs to more intricate detail work
0.5" thickness provides superior rigidity and break resistance compared to fragile 0.2" curves
Clear optical-grade plexiglass for unobstructed sight while working
Back-carved ruler tick marks sit flush on the work surface and ensure precise measurement and symmetrical pattern layout
They are designed thick, so you can trace with awls or cut against the curves with box cutters, knives, and rotary cutters!

BUILT FOR ALL YOUR PROJECTS

Whether you're cutting curves directly into leather, establishing symmetrical curves on patterns, or scaling designs from small to large formats, these curves adapt to your needs.

THE 0.5-INCH CAST ACRYLIC DIFFERENCE

Premium Materials

Did you know cast acrylic is around 17 times more shatter-resistant than glass? These tools are crafted from high-quality, 0.5" cast acrylic plexiglass, which is much stronger than other 0.2" 'extruded' acrylic tools. Cast acrylic is also more resistant to damage from chemicals like alcohol-based dyes, deglazers, and tannins commonly found in leathercraft.

Quality Assurance

Every product is quality-checked and securely wrapped to ensure safe shipping and durability right out of the box.

Designed By and For Leather Crafters

Each tool was designed and tested in a real leathercraft workshop - That's tried-and-true craftsman quality you can trust.

30-Day Replacements

These tools are strong! But sometimes, things happen. If any of the original tools break within the first 30 days of purchase, I'll send you a free replacement.
