Perhaps my lack of sleep is blurring my memory, Fernando. I was trying to remember those daggers discussed on the Ethno side that closely resemble and are often mistake for plug bayonets. They were from the isles between the U.S. and Morocco/Spain. Forgive my clarity-just worked a looooong week at the hospital!
Looked it up- the Canaries. Than again, perhaps I was remembering the Albacete type-
Anyway, I was trying to find a pic of the dress dirks with this type guard, but no luck so far. I still think they are dirks and provincial with their hilts.
