The Mallet Carlos Uses at the Academy
A proper break-in mallet is heavier and more balanced than a standard wood mallet. The weight distribution matters — too light and you're not impacting leather fibers at the right depth; too heavy and you damage laces and leather around the pocket.
Kachi's break-in mallet is hardwood, weighted for proper impact distribution, and identical to the tool Carlos uses at the Kachi Baseball academy when prepping gloves for academy players.
How to Use It
- Place the glove pocket-up on a flat surface.
- With the mallet, strike the center of the pocket with firm, controlled impacts — 30–50 strikes on the first session.
- Alternate between pocket center and surrounding palm/heel areas.
- Work the finger stalls by placing the mallet head inside each stall and applying pressure.
- Rest the glove with a ball in the pocket for 24 hours.
- Repeat daily for 5–7 days.

Kachi was started by two former MLB pitchers — Julio Teherán, two-time All-Star with six consecutive Opening Day starts for the Atlanta Braves (tied with Warren Spahn), and Carlos Castillo, who pitched for the White Sox and Red Sox across an 18-season career that took him through Japan’s NPB and Taiwan’s CPBL — the leagues where Japanese Kip leather is the professional standard.
