Harrows grade their ranges more finely than most, with several running six weights in single gram steps on one barrel length — so settling on your exact weight is a matter of trying rather than guessing between two.

The tungsten grades reach 97% on the Wolfram Infinity and Magnum, which is among the highest in production anywhere and lets a 26g barrel sit inside 7mm.

Dave Chisnall's Chizzy ranges stay under 7mm across every weight, suiting the fast scoring he is known for. Ryan Searle throws the heaviest darts on tour and his signature range runs to 32g. The Gold Titanium Anniversary editions reissue five barrels from Harrows' own history, including the first 95% tungsten dart they ever made.
