Reading the Pursuits section of the Wall Street Journal today I found an interesting ad. It showed a machete like tool that has a curved blade on one side and hooked shaped blade on the other. I have been looking for something like this to clear brush on some rural land that has quite a few briars and overgrowth.
The company that makes it is in Pennsylvania since World War II. Reading their website it appears to be a tool the military used when serving in jungle environments.
