A strange weapon (tool?) with arabic marking

[ariel]

I think that "torture tool" or "executioner's tool" might be more enticing and exciting than just a "butcher's cleaver" ( for a certain kind of creeps, at least). Brings more moola.
Several times in my e-bay career I came upon a misidentified beheading sword offered for a song. Did not even bid on it. Did not want it to enter my house even for a moment.
