Harrows Wolfram Infinity: Specs & Owner Reviews

The Wolfram Infinity is a 97% tungsten parallel barrel with a full-length grip across six weights. Here are the specs and how owners and reviewers rate it.

At a Glance

One of the slimmest barrels on the market thanks to a 97% tungsten build, with a moderate full-length grip and a large, strongly positive body of owner feedback. The recurring complaint is not the barrel at all, but the plastic shafts it ships with.

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. Rather than throwing these ourselves, this page gathers the specifications Harrows publishes and the reception from a large pool of owners.

How They’ve Been Received

How it's been received 4.5 out of 5 · 888 reviews
Overwhelmingly positive
Negative Mixed Positive
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 Reviewers Say

One buyer, who describes seeing these regularly at super league level, was specific about how they throw:

“The balance is great, the grip isn't too grippy and the darts release well from the hand, they are great quality and a real joy to throw.”
— a verified buyer

A second buyer liked the barrel just as much but ran into the problem that dominates the critical feedback:

“Nice looking, nice feel very grippy and very narrow so if your good enough to group your darts close then much better chance of getting 3 in a treble. But you should know that the stems are plastic and two days in I'm a dart down as it's just snapped when it landed on the floor after a bounce out.”
— a verified buyer

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 3 out of 5 on its own scale, 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.

Who They Suit

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. 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.

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.
