Tandy Leather / Hole & Strap Punches
Tandy Craftool 5 mm Buttonhole Punch
One Craftool 3779-04 punch in the selected 3/16 in (5 mm) buttonhole version for leather stud closures.

CHOOSE THE TOOL FOR YOUR WORK
Match the closure profile before the size label
This Craftool is a specific closure tool: it is intended to form a button-stud opening rather than a plain circular hole or a long buckle slot. That makes it relevant to wallet, pouch, notebook-cover and strap closures that use this opening profile.
The selected version is labeled 3/16 in (5 mm), model 3779-04, with one tool specified. The seller describes steel construction and positioning the tool before striking it with a mallet. The nominal size does not describe the complete slot geometry or prove compatibility with every stud called 5 mm.
Compare the small rotary Beadsmith if you need simple circular holes, or the WUTA square assortment if corners and straight sides are required instead. Neither reproduces a dedicated buttonhole profile. A claim of one-strike cutting is not a material-thickness rating; confirm the fitting and working setup before using it on a finished item.
