A wooden chakram made from maple and mercilessly hurled in the oncoming enemy hordes... and watermelons!
The famous death circle of the Sikhs, and also wielded by Xena Warrior Princess in the late 1990's. Mine is made from maple and finished boiled linseed oil for a easy to renew finish.
If you round the edge over (as I did before tossing it at people) it then becomes a wooden Aerobie®! It actually flew quite nicely!
I really liked this build and it was supremely satisfying to not only get it to stick into the watermelon but also that the aerofoil worked so well to give it lift as a frisbee!
That makes two error free builds in a row. Must be some sort of record!
