Firehole Stones, from Firehole Outdoors, come as the obvious counterpart to the Firehole Sticks. A matte coated range of tungsten beads designed for use with either barbed or barbless hooks in a vibrant and exciting range of colours.

Round tungsten beads sized true, drilled clean, and weighted the same bead to bead. The head of the fly should be the part you never have to think about.

On the Metal

Tungsten beads are made from tungsten heavy alloy rather than pure tungsten: tungsten powder sintered with a few percent of nickel and iron. Pure tungsten is brittle and difficult to work, and the binder is what makes a bead you can handle without it chipping.

Ours runs 95% tungsten, which puts it at about 18 g/cm³, roughly 1.6 times the density of lead. The category generally sits between 90% and 97%, a spread of about a gram and a half per cubic centimetre. On a 3.0mm bead that is a difference of about two hundredths of a gram, where going up one bead size is twelve hundredths. Size moves weight roughly six times harder than purity does.

Of course, if you want to create all sorts of natural looking streamer fly patterns, then our ever growing range of natural hairs and furs is the ideal place to start for something different to the synthetic option.
