Rondel Dagger Ragim with triangular stabbing blade
The triangular blade would was principally designed for use with a stabbing action, either underarm, or over arm with a reverse grip (think ice pick). Rondel daggers were ideal in battle for puncturing chain mail, and although they would not have been able to punch through plate armour, they could be forced between the joints in a suit of armour and helmets. This was often the only way in which a heavily armoured knight could be killed.
