A historically accurate 15th century English rondel dagger, featuring a rigid quadrangular blade designed for penetrating gaps in armor. A classic knightly sidearm of the late medieval battlefield.

This rondel dagger is a faithful reproduction of a 15th century original preserved in the Royal Armouries collection, representing the type commonly carried by knights and men-at-arms during the later medieval period.

Rondel daggers are defined by their distinctive circular guard and pommel, which provide secure hand positioning and allow for powerful thrusting techniques. Unlike cutting daggers, this form is purpose-built for penetrating the gaps in armor, particularly at joints and weak points in mail and plate.

Rondel daggers were not only battlefield weapons but essential sidearms—used in grappling situations where swords became impractical. Their compact form and specialized design made them one of the most important personal weapons of the medieval warrior.
