Tengu Blade

From MMKB

Tengu Blade is what Tengu Man uses in Mega Man and Bass. It is a multitasking sword weapon that can send a projectile as well as being used as a slashing weapon. It can bounce off of walls, and can also be used as a dashing weapon (similar to Charge Kick) by sliding (Mega Man) or dashing (Bass) with the item equipped. This is Magic Man's weakness, which can actually slice him into pieces (although Magic Man returns to one piece afterwards). The reason for this may be because of the phrase "cutting the deck."
