Not sure exactly where this machete type knife came from or what it was used on, but the green cloth sheath has Korea on it, but can't see any markings on knife, but could be because of the rust on the blade. The knife is approx. 19 1/2" long and the blade is rusty and does have chips and dings out of it. The sheath (cloth) is very stained with what looks like blood, but could be oil or who knows and the sheath also has holes and is torn.
