Hokay:
Approx. 8 inches OAL. Weight, haven't measured, but I'd guess it at 1/3 to 1/2 pound. Metal is wrought iron, thickness is 1/2inch. Finish is brushed steel, then sprayed with 2 coats of matte black Rust-oleum.
I have dropped tested these on cement, from a height of 8 feet, dropped point first. The cement always loses. They are extremely robust throwers, and also make a nasty fist-load or hand-held defense tool (think "big kubotan"). I would recommend these for strong or accomplished throwers, preferrably stong AND accomplished throwers.
I may take orders on these in the near future, or on similar designs. I don't keep them in stock, but make then as orders come in. A dozen takes about two months to do right. I prefer to sell only to MA practitioners and collectors, as I don't think kids or the avg. citizen need 2B running around with these monsters. Currently, I am producing these only for the Bujinkan folks, to their specs.
