Product Description
Daiwa WD4-0201 Handle Knob – M-ONE UTD & Vintage Upgrade
Upgrade the grip and control of your mooching reel with the Daiwa WD4-0201 Handle Knob. This is the genuine OEM replacement knob found on the modern M-ONE UTD series. Featuring an ergonomic, soft-touch design, it provides superior traction in wet and cold conditions compared to the hard plastic or wood knobs found on earlier generations.
This part is widely used as the primary retrofit solution for anglers looking to restore vintage M-ONE reels, as the original "old-style" knob kits are now obsolete.
Key Features
-
Genuine Daiwa Part: Factory correct for M-ONE UTD series reels.
-
Ergonomic Grip: The modern "Soft Touch" rubberized composite material offers a secure hold, reducing hand fatigue during long battles with salmon.
-
Non-Slip Texture: Improved surface texture prevents fingers from slipping off the handle when wet or slimy.
-
Retrofit Capable: The only factory-approved replacement for the discontinued vintage M-ONE handles (requires matching screw/cap).
Model Compatibility
This handle knob is a direct fit for the following reels:
-
Daiwa M-ONE UTD 400 (Ultimate Tournament Drag)
-
Daiwa M-ONE UTD 200
-
Daiwa M-ONE (Vintage/Standard) – Note: When installing on a vintage M-ONE to replace a wood/hard plastic knob, you must also purchase the UTD-style screw and cap.
Schematics & Installation
If you are upgrading a vintage reel, simply swapping the knob is not enough; the mounting hardware differs. You will likely need the Knob Screw (WD4-0301) and Knob Cap (WD4-0401) to complete the installation.
