I found this at an online auction, the description goes as"
"A mix of a Visayan Bolo and a Moro Kris? It is certainly of monstrous dimensions: 37 inches long (In scabbard). The blade is wavy, deadly sharp and ‘only’ 30 inches long (For comparison purposes it is shown below next to a rather big 20 inches blade Moro Kris). The handle is a Deity shaped carved from horn and the cross guard is steel. Wood scabbard bound with brass wires. Good condition. Few blackened spots on the blade. Cracks on the scabbard (But hold solid) and few of the brass wire bands are damaged and few missing. Very Unusual piece."
