The Nzappa zap (also referred to as zappozap, nsapo, kilonda, kasuyu) is a traditional weapon from the Congo similar to an axe or hatchet.
It has an ornate wrought-iron blade connected to a club-like wooden handle, often clad in copper, bronze or brass.
[1][2][3] Largely ceremonial, it can be used much like the American tomahawk, both thrown for short distances and wielded as a weapon in hand-to-hand combat.
It differs from the usual axe style, in that the blade mounts to looping prongs that affix to the shaft.
[5] The weapon is the etymological base of the name "Zappo Zap", an infamous Songye tribal group once active in the Congo Free State.
