The Highland Dirk, certainly since the 15th century, has been distinctive from European daggers in having but a single edge, the heavier blade perfectly balanced for use as a short sword.
This example of the oldest style of Dirk has a simple carved knotwork pommel and plain Scabbard.
All Dirks have the finest quality hand wrought tempered steel blades, with solid cowhide sheaths, and come supplied in a gift box, with historical notes
