Rounding jacks or brim cutters are a hand tool used for cutting a brim to a specific with all the way around. They are best used for stiffened felt, but can be used for other hats with care (please try it out on a sample first). 

***Add a personalised design to your Wonder Jack – choose this product if you wish to do so. We’ll communicate with Michal and get it on your new jack for you to approve before it’s sent. The process will take a few weeks.***

If you don’t need a personalised design, pick one of mine –

Wonder jacks are hand made in Germany and Millinery Hub is the sole agent in Australia. I have a couple of designs available, but you can have custom artwork printed on yours do add character and personal flare. It will require a few weeks lead time, but no more cost. If you order one, I will contact you about what you would like.

  • Readily available interchangeable blades for maintaining a sharp edge. 
  • The scale is in centimetres, but new models have both inches and centimetres. 
  • Precise cuts in accordance with the highest standards.
