I picked up the term "UFO" to describe unknown sets of darts from dartsnutz.net. I love the term. First, it is cheeky. Second it borrows from the mystique created by The X-Files, which I am recently watching (and loving) for the first time ever. I cannot believe I never watched that show before.
These darts, despite being much more massive than other darts in the same weight range, are a meager 20 grams. This, and the fact that they have a "silvery" hue to them, and somewhat slickery feel, makes me think that they are not tungsten at all, but rather a nickel-silver dart. Funny how few nickel-silver darts there are out there. There are literally a gazillion brass darts available, and just as many tungsten darts, but darts of this composition are significantly fewer, in my humble opinion.
As currently dressed:
Points: Bottelsen Hammerhead Points
Barrel: 20 gram Nickel-Silver
Stems: Short Aluminum
Flights: Standard Mylar (folded)
Anyway, the above darts are likely Bottelsen darts because when I got them they came with a Bottelsen leather flap wallet, and the mylar folded flights you see in the pic. Not long ago I reached out to Bottelsen to see if there was anyone there with copies of old catalogs that I could look through and got quite a cold shoulder from them. This makes me sad a bit. They are a great dart maker and have contributed to the substance of the dart universe significantly. I wish there were someone there who was more of a dart geek, cared about preserving (and sharing) their own history, etc.
If I am ever a dart maker I will never, never, ignore a fan who cares about the history of darts equipment!
