Strange Dagger in 16th Century Dutch Painting

Here's a close-up of the hybrid ballock-rondel dagger shown in The Arrest of Christ... What I find interesting about this is we see style elements of the earliest pre-Jacobite dirks (e.g., disc pommel and ballock lobes) that were to evolve from Highland ballock daggers over the next century.
