Native Way G202

While the socketed trilobate arrowhead is the most common and preferred type for our period, Native Way's model G202 (their G200 looks very similar) belongs to a type attested from findings at Persepolis and is therefore an option for the Achaemenid reenactor.  I also happen to find it very cool-looking.

It's molded from an original and cast in a "lightly leaded" tin bronze which as you can see cleans up very nicely.  It is unfortunately cast rather thick and heavy at 12 grams, but filing and trimming the tang (above, I've cut the tang down by about a third) will help, and also let you define the mid-rib more clearly.  I've managed to get the one I've worked on down to around 9g and could go further.  Because the dust contains lead, I'm guessing your should avoid high-speed power sanding.

The best thing about these, along with being perfectly authentic, is they're very inexpensive as far as reproduction arrowheads go:  Rough-cast, they retail for $3 each, and for the U.S.-based reenactor, shipping costs are far lower than overseas options.  If you don't mind doing some of the work yourself, these are a great option for the reenactor on a budget.
