The Wolfram Infinity is the second generation of the Harrows Wolfram, a barrel the company says was one of the most popular on the market for years before this version replaced it. Harrows kept the slim profile that made the original sell and reworked the grip, finishing the barrel in black titanium nitride with red metallic detailing.
At 97% tungsten this sits near the top of what is commercially available, above the 90% that most professional-grade barrels use.

How They Compare
Spec sheets mean more next to the alternatives. Here is the Harrows Wolfram Infinity against three similar darts we have covered, using the figures each manufacturer publishes.
| Harrows Wolfram Infinity | Dimitri van den Bergh 95K (opens in a new tab) | Daryl Gurney Signature Edition (opens in a new tab) | Luke Humphries TX3 (opens in a new tab) | |
|---|---|---|---|---|
| Price band | High End | High End | High End | High End |
| Tungsten | 97% | 95% | 95% | 90% |
| Weights | 21g to 26g | 22g, 23g, 24g | 23g | 22g, 24g |

Who They Suit
| If you... | Fit | Why |
|---|---|---|
| Like a light, slim dart | Good | Lightest is 21g with a 6.4mm barrel |
| Want a thick, heavy barrel | Partial | Heaviest is 26g at up to 7mm |
| 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 | Partial | Barrel length is 50mm |
| Want quick-swap points | Poor | Standard points rather than a quick-swap system |
| Are working to a tight budget | Poor | It sits in the High End price band |
The slim profile is the reason to buy these. At 97% tungsten a 24g barrel measures just 6.8mm across, and players who already group well get a real benefit from the extra room in the treble bed. The moderate grip and middle weight distribution make it a fairly neutral barrel that does not force a particular hold, and six weights give plenty of room to find the right one.
Budget for replacement shafts on top of the purchase price, because the feedback on that point is consistent. Harrows’ newer Wolfram Trinity is the same slim 97% idea with one-piece Solo flight and shaft units and swappable Quick Points in the box, though it costs more. If you would rather not pay premium money for a non-signature barrel, the Winmau Daryl Gurney Signature Edition is 95% tungsten in a similar price bracket, though with a much smaller pool of feedback behind it. If a slim barrel is not what you are after, our guide to dart barrel shapes covers how the alternatives change the way a dart sits in the hand.
What Owners Say
The headline score is 4.5 out of 5 from 888 reviews. This figure comes from buyer reviews on a major retailer rather than a manufacturer-hosted page, and the sample is unusually large for a darts set, so it is a reliable independent read. Harrows also hosts reviews on its own site, but only a couple, which is too few to draw anything from.
Two things come up repeatedly in the feedback. The first is the slimness: at 97% tungsten the barrel is narrower than most sets at the same weight, and buyers who group tightly say it gives them a better chance of three darts in a treble bed. The second is the shafts. Several owners report the plastic stems snapping after a bounce-out, and the criticism is consistent enough that one enthusiastic reviewer recommends stocking spares from the outset. Nobody appears to be complaining about the barrel itself.
What owners consistently praise
- Very slim barrel for its weight, which owners say helps them group tightly
- Balance and a clean release, with a grip that holds without clinging
- Six weights from 21g to 26g, so the range covers most preferences
- Match weighed to within 0.05g across the set
Common criticisms
- The bundled plastic shafts snap readily, with several owners losing one within days
- Buying replacement stems and flights is effectively part of the cost
- Sits at the premium end of the market for a non-signature barrel
The Grip: What to Expect
Harrows rates this as a medium grip, describing an intense all-over grip created by CNC-turned ring cuts running the full length of the barrel. The weight sits in the middle rather than being front or rear loaded.
Owner feedback lines up with the manufacturer here, which is not always the case. Buyers describe it as noticeably textured without being aggressive, and the reviewer quoted above specifically praised the grip for not being “too grippy” while still releasing cleanly. If you throw with a light touch and dislike a barrel that grabs, this sits in comfortable territory. Anyone who needs heavy texture to lock their fingers in place will find it moderate.
The Consensus
Across a large and consistent body of owner reviews, the Wolfram Infinity is rated highly, and the praise is specific rather than vague: the slimness, the balance and a grip that holds without interfering with the release. The 97% tungsten construction is doing real work here rather than being a spec-sheet number.
The one persistent complaint has nothing to do with the barrel. The Supergrip Fusion shafts in the box are plastic and owners report them breaking easily, to the point that regular players treat spares as a running cost. Weighed against a barrel that buyers rate as genuinely excellent, most seem to consider that an annoyance rather than a reason to avoid the set.
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.
