That sounds very fun :D It very roughly reminds me of what I used to play as a kid in Sweden, which was called "Land and country", though it had a lot less knives.

Each player started with a sector ("country") of a slightly larger circle (~3m diameter), taking turns in order to throw a small stick/shovel into some other country, thus declaring "war" on them. The person who gets "attacked" has to step on the thrown item with everyone else trying to run away as far as possible. Once the item has been stepped on, the attacked person tries to throw the item at a player of their choice. If they hit, they get to "annex" as large a region of that country as they can without lifting either foot from some starting position in their home country.

It always was my favorite game despite apparently not being Buddha-friendly :)
