My everyday sgian dubh came from Keltoi. It was shaped to have somewhat of an edge, but not really enough to be a functional cutting tool. So I went to work on it with my Lansky knife sharpening tools. Now it has a proper knife edge, and I consider it a functional sgian. It's perfect for the normal tasks I need it to do when kilted (like cutting sausages, lol). As long as I clean it well when I get home, give it a brief honing, and oil the blade, it's a great tool. I probably wouldn't use it for serious knife work where a better quality blade would be called for, but it suits my needs as a daywear sgian.
