It's the modern take on the vintage Hardy "Aero" fly accessory - which was a tiny metal two-bladed propeller type device in Hardy's 'Aero' flies.
The modern take is called the 'Gazelle', and is advertised in the UK by 'Flyman UK' on his webpages.
I'm fairly sure that you would be able to get an able engineer to make you a metal punch of the right shape & size, and you could have these made out of copper or brass sheet for pennies.
If people concentrated on the really important things in life, there'd be a shortage of fishing poles (spey rods). Doug Larson
