“The DF and later DF2 Heaven fairways round out the On The Screw metalwood family with an easy-launching, forgiving profile. A boutique choice for the player who already has the Muziik driver and wants a matched wood.”
Muziik is a Japanese boutique maker best known in the West for its aftermarket 'Zelos'/multi-material shaft work; the On The Screw DF fairway wood (circa 2017) applied that same fine-tuned-weighting philosophy to a full clubhead. It uses a 6-4 titanium body mated to a computer-machined stainless-steel sole plate whose weight is tuned by loft (80g on the #3 and #4, 84g on the #5, 61g on the #7), with a set of weighted screws adding up to 100g of total sole mass on the 7-wood. The high-faced, deep-backed shape is designed to look confidence-inspiring at address in either a silver or black ion-plated finish, aimed at Japanese golfers chasing extra carry and a high, penetrating flight from the deck.
A genuine JDM niche product rather than a mainstream one: it is documented mainly through Japanese equipment blogs (golfclubtesthitting.com), Japan-based retailers (muziik.tokyo, golf-shop.jp), and import listings on eBay/Monster Golf Shop rather than mainstream Western golf media. Muziik continued the line with a DF2 HEAVEN successor, which signals enough enthusiast demand to iterate, but there is no broad Western cult reputation for this specific model.
Best suited to Japanese-market equipment enthusiasts and better ball-strikers chasing a boutique high-COR face and premium aftermarket shaft pairing (Tour AD, ATTAS); not a sensible pick for a golfer who wants mainstream US retail support, warranty, or fitting infrastructure, or who is simply chasing the lowest-cost forgiveness available.
Released around 2017 alongside Muziik's driver-focused On The Screw DD line, competing in Japan's premium aftermarket/boutique segment against Ryoma, Bridgestone Tour B and Honma; later replaced within Muziik's own catalog by the DF2 HEAVEN fairway wood.
The multi-metal sole construction concentrates weight low and deep for a genuinely high, easy launch and decent ball speed retention, but the head profile is compact and boutique-shaped rather than an oversized max-MOI design - toe and heel mis-hits lose more distance than they would on a mainstream giant-headed game-improvement fairway wood.
Calibrated across the whole catalog — a tour blade scores low here on purpose; it means control, not ease.
Used imports move mainly through eBay Japan-based sellers; a complete club with a premium aftermarket shaft (Tour AD, ATTAS) realistically sells for roughly $150-300 depending on shaft and condition, against new/import retail in the $700-950 range.
Reading is one thing — hitting is another. Book a bay and see the numbers for yourself before you buy anywhere.
