Did Scottish highlanders manufacture their own weapons, or were they all imports?

A bit different than the "Highlander' series and movies I'm afraid. Virtually all Highland and Lowland swords used imported blades, typically from Germany. You might look up ANDREA FERARA online, a commonly seen name on Scottish blades.
While dirks evolved from early British daggers, which had blades produced locally in many locations, by the late 16th century the blades of full size swords often were repurposed into dirk blades as well.

Where did you find the notion that only lowland smiths created blades?
While the Scots used foreign blades for swords, they did indeed fashion hilts (commonly termed 'basket hilts') in both Glasgow (Highland) and Stirling (lowland) as well as various other locations with 'sword slippers' (cutlers).
