The WhipperWill Rounding Jack is designed for hatters who want a simple, repeatable way to cut clean, consistent brims without the cost of traditional specialty equipment.
Designed and manufactured by WhipperWill Hats in Canada, this tool features an adjustable sliding carriage with an easy-to-read inch scale, allowing you to set your desired brim width and maintain a consistent cut around the crown.
The curved fence follows the crown while the lower support plate helps keep the brim properly positioned during use. The replaceable snap-off utility blade is held at an angle for a smooth, controlled cut, while four locking screws secure the carriage once your desired brim width is set.
Features:
Adjustable brim cutting width
Inch scale with 1/8" increments
Four-point locking carriage
Replaceable 18 mm snap-off utility blade
Secure M5 blade clamp with captured nut
Curved crown-contact fence
Hinged lower brim support
Designed for cowboy hats, fedoras and other felt hats
User-replaceable standard hardware and blades
3D printed construction
Designed and manufactured in Canada by WhipperWill Hats
Ideal for professional hatters, small hat shops, hobbyists and anyone looking for an affordable alternative to traditional rounding jacks.
Please note: As with any hand-operated cutting tool, a small amount of practice is recommended before using the rounding jack on a finished or valuable hat. Always use a sharp blade and make controlled, gradual cuts.
Included: Fully assembled WhipperWill Rounding Jack.
