Harrows Magnum 97% Tungsten, 27 grms
Zeeple has asked for a closer look at the Magnums, so here we go.
The knuring is very light, and almost more like an engraved diamond pattern. The middle dart has some of the deep grooves missing, which leads me to suspect they are "rejects". I definitely would have sent them back if I'd paid £30 for them rather than them being a gift. Its purely cosmetic though, and they throw really well.
They are exactly 5 cm in length, with 2.5 cm points. The 97% tungsten content means they are extremely durable ; After 3 months of hammer they are still unmarked in any way, and remain in an almost new condition. This was not the case with the 85% tungsten darts I used to use, and they'd have all sorts of marks after this time. Also, there is no visible oxidation with the Magnums to date, and they remain shiny.
