This custom designed Hat Making Tool was a commissioned item, and has been SOLD.


I’ve been pretty busy the past few weeks working on Maloof-Inspired rocking chairs, and since they aren’t finished yet, I’ve not posted much for projects lately. I did take a break from all the rasping and sanding though to design and build this tool late this week.

This hand tool was designed to add a small groove around the top of a leather Sweat Band on a custom hat. It is made to exactly match the old Borsalina Fedora sweat band. The specifics of the groove size and distance from the top are proprietary. The customer sent me photos of the sweat band he was trying to replicate, and then I scratched my head a couple of weeks and then designed the tool for that purpose. I make quite a few custom hunting knives, and so I decided to make the handle as ergonomic and decorative as I do on my knives.

  1. Yellow Brass
  2. Brazilian Walnut
  3. Abalone Shell
  4. Heat Treated Steel

Thanks for looking,
Mark DeCou
