Custom Fabrication

Custom Bow Grips

Hand-fit bow grips built to order—each one shaped by the archer, molded in platinum-catalyzed silicone, and cast in rigid polyurethane with softer Flex-it zones crosslink-bonded where your palm and fingers need compliance under draw.

  • Built to your hand—not a catalog profile adjusted with shims
  • Platinum silicone molds preserve fine surface detail for repeatable casts from one pattern
  • Rigid polyurethane body with Flex-it–type soft zones in palm, thumb, and finger contact areas
  • Crosslink-bonded soft and rigid sections—one integrated grip, not a glued insert
  • Duplicate casts available once your silicone mold is on file
  • Iterative shape–test–refine workflow with competition use in mind

How to order

Each grip is a small fabrication project—shaped by you, built in the workshop.

Step 1

Tell us about your setup

Reach out with your riser model, current grip issues, and whether you are starting fresh or refining an existing shape. Photos of your hand on the bow help.

Step 2

Shape & prototype

We work with you to sculpt a prototype grip—adjusting swell, thumb shelf, palm hook, and finger grooves until the hand position feels natural at full draw.

Step 3

Mold, cast & deliver

A platinum silicone mold captures the approved shape. Polyurethane and Flex-it zones are cast, finished, and test-fit before your grip ships—or before duplicate pulls if you want spares.

Fabrication process

The same platinum silicone, polyurethane, and Flex-it workflow documented in the Development Laboratory.

Step 1

Shape & customize

The archer builds or sculpts a prototype grip—adjusting swell, thumb shelf, palm hook, and finger grooves until the hand position feels natural at full draw.

Step 2

Silicone mold

A platinum-catalyzed silicone mold is taken from the finished prototype, preserving surface detail and allowing multiple polyurethane pulls from one pattern.

Step 3

Rigid polyurethane cast

Two-part polyurethane is poured into the mold to form the main grip body—light, tough, and stable for mounting on the riser.

Step 4

Flexible soft zones

Selected regions (typically palm face, thumb contact, and finger hooks) are cast in softer Flex-it–type flexible rubber for vibration damping and tactile feedback.

Step 5

Crosslink bond

Soft and rigid sections are cast and cured so the elastomer crosslink-bonds to the polyurethane—creating a single integrated grip without separate glue joints.

Step 6

Finish & mount

Flash is trimmed, mounting surfaces are drilled or faced as needed, and the grip is test-fit on the bow before final use or duplicate casts.
