The Wolfram Trinity is the newest barrel in Harrows’ 97% tungsten Wolfram range, launched in the company’s January 2026 product drop. It is fully CNC-milled, finished in bronze titanium nitride and black electroplate, and the steel tip set uses Harrows’ Quick Point system, so you can swap point length without a repointing machine.
The box is fuller than most. Harrows’ Solo integrated flight and shaft units come fitted, along with a keyring tool that changes the points and holds spares.
Key Specifications
The steel tip version comes in six weights, and all of them share the same 51mm barrel, so the extra weight shows up as extra width.

How They Compare
Spec sheets mean more next to the alternatives. Here is the Wolfram Trinity against three similar darts we have covered, using the figures each manufacturer publishes.
| Wolfram Trinity | Harrows Wolfram Infinity (opens in a new tab) | Luke Littler G1 (opens in a new tab) | Luke Littler World Champion (opens in a new tab) | |
|---|---|---|---|---|
| Price band | Premium | High End | Premium | Premium |
| Tungsten | 97% | 97% | 90% | 90% |
| Weights | 21g to 26g | 21g to 26g | 22g, 23g, 24g | 23g |
| Barrel length | 51mm | 50mm | 50mm (22g), 52mm (23g, 24g) | 52mm |
| Barrel diameter | 6.5mm (21g) | 6.4mm (21g) | 6.5mm (22g) | 6.5mm |
The Trinity and its older Infinity sibling are near enough the same barrel on paper, both 97% tungsten across the same six weights. The step up to the Premium band buys the Quick Point system and the Solo flights rather than a slimmer dart.
Who They Suit
| If you... | Fit | Why |
|---|---|---|
| Like a light, slim dart | Good | Lightest is 21g with a 6.5mm barrel |
| Want a thick, heavy barrel | Partial | Heaviest is 26g at 7.15mm |
| Want grip cuts along the whole barrel | Good | Grip zone runs the full length of the barrel |
| Want a very smooth grip | Partial | Medium grip, according to the manufacturer |
| Prefer a short barrel | Poor | Barrel length is 51mm |
| Want quick-swap points | Good | Quick Point system with a swap tool in the box |
| Are working to a tight budget | Poor | It sits in the Premium price band |
Players who like a fat barrel to hold on to should look elsewhere, because slimness is the whole point of 97% tungsten. If you want the same slim Wolfram profile for less and can live with fixed points, the Harrows Wolfram Infinity sits a band lower. Our guide to brass vs tungsten darts explains why a higher tungsten percentage narrows the barrel at any given weight.
What Owners Say
The headline score is 4.5 out of 5 from 45 buyer reviews on a major UK retailer, with 82% of them five-star and 6% one-star. Harrows’ own product page shows 15 reviews, every one of them five-star, but that page is manufacturer-hosted and those tend to run high. One independent reviewer covered the set at launch and called it grippy and good value for everything in the box.
The praise centres on the grip and build quality, with several owners saying the darts feel well made for the money. The low scores are few and mostly about fit rather than faults. One buyer loved the grip but returned the set because the 97% barrel was too skinny for their fingers, and another rated it as a quality item that simply did not suit them.
What owners consistently praise
- A grip that holds firmly without feeling harsh on the fingers
- Build quality that owners say feels worth the price
- Quick Points that let you change length without a repointing tool
- A full set in the box, including Solo flights and a points tool
Common criticisms
- Slim enough that some players with bigger hands find it hard to hold
- One owner had bounce-outs with the Solo units and swapped to standard stems and flights
- Premium pricing, which even happy owners point out
The Grip: What to Expect
Harrows rates the grip as medium and lists the grip zone as full length, with middle weight distribution. Deep milled cuts run along the barrel either side of a bronze logo band, so there is no smooth section to hold.
Owners read it as grippier than a medium rating suggests. Buyers who like a grippy dart say it suits them, and the independent reviewer found the black coating added grip on top of the milling. Nobody we found called it harsh. If you throw with a light touch and like a dart that slides out of the fingers, try the set before you buy.
The 30mm points are longer than the usual 26mm. One owner found them a touch short and moved to 35mm, which is the sort of change the Quick Point system is built for.
The Consensus
Owners rate the Wolfram Trinity highly. The grip and build quality draw the most praise, and the Quick Point system goes down well with the buyers who mention it. The negatives are about fit and price rather than faults. It is a very slim barrel, which suits tight groupers but not everyone’s hands, and it costs noticeably more than the Infinity, which is a similar barrel on paper.
The pool of reviews is still fairly small for a set launched this year, and only one independent write-up exists. What there is points the same way.
How we compile this page
We don’t throw every dart ourselves. Instead we gather the manufacturer’s published specifications and weigh up the reception from owners and independent reviewers, then flag where they disagree so you can make up your own mind. Where a headline rating comes from manufacturer-hosted reviews, we say so, because those tend to skew positive.
