For those who don't want to click, here is what struck me as interesting:

"This Sgian Dubh is called the GLENURQUHART and is a reproduction of a Sgian Dubh which was carved from a piece of Glenurquhart Oak. The original was designed and created by Rab Gordon in his studio that overlooks Loch Ness. "

Just thought it was interesting!
