This is a precision 3D printable master model inspired by the legendary Relax Kopyto — one of the most iconic soft plastic vibrotails in fishing history, designed by Witold Kowalczyk in the early 1990s . This model is a replica inspired design that closely matches the distinctive Kopyto profile known for its intense tail action and unique hoof paddle. It is intended for mold making purposes: use it to create silicone or RTV molds for small scale production of soft plastic lures.

Design Features:

High profile shad body design that provides strong frontal water resistance, creating a seductive rolling action even at the slowest retrieve speeds

Long narrow tail section with three distinct notches allowing the tail to move freely and pound aggressively

Massive wide paddle tail in the shape of a hoof (Kopyto in Polish) that creates intense water displacement

The tail activates at minimal retrieve speeds — the lure works effectively on steady retrieve, jigging, lift and drop, and even on the fall before retrieve begins

Minimal lateral body movement during retrieval while the tail produces rhythmic vibrations

Durable elastic material geometry designed to withstand multiple predator attacks

Preformed ventral hook slot for easy jig head and offset hook rigging

Available in multiple size replicas: 2.5in 6.3cm, 3in 7.6cm, 4in 10cm, 5in 12.7cm, 6in 15.2cm

Optimized surfaces for easy demolding

Important note: This is an inspired replica design based on the original Relax Kopyto lure created by Witold Kowalczyk in the early 1990s . Not an official Relax product. For personal use and small batch production only.
