The Bollock dagger was popular in Scandinavia, Flanders, Wales, Scotland and England between the 13th and 18th centuries, in particular the Tudor period. Within Britain the bollock dagger was commonly carried, including by Border Reivers, as a backup for the lance and the sword. Many such weapons were found aboard the wreck of the Mary Rose. The bollock dagger is the predecessor to the Scottish dirk.
