In November 1715, the death knell of the Rising of '15 sounded at Sheriffmuir. The battle itself had no clear winner, but the highland clans were essentially cut to pieces.
The story goes that on the evening before the battle, the Macrae men danced the sword dance on the roof of the armoury at Eilean Donan castle, such was their courage and confidence. On the morning after the battle there were 58 widows in Kintail, Scotland, named Macrae. One of those men was an ancestor of mine, John Macrae, and the original of this dirk belonged to him.
The original was made in Inverness in 1700. I was fortunate enough to get to take a close look at it, (no photography is allowed inside the castle) and study it (under strict supervision) for a time. I made numerous drawings and measurements of it, and this is about as close as I can come to a copy.
