I have 2 sgian dubhs, one is stag-handled and has a real blade, the other is wooden-handled and has a metal but ceremonial blade. I only ever wear the "real" one because I like to be adventurous and wear a real knife justifiably, although I have used it as a knife for mundane things like sharpening a pencil etc. I rarely wear it in England except for indoor events such as dancing, because I doubt that the English police would be too understanding.
