What about plug bayonets?

[fernando]

We call them baionetas de 'caça' (hunting). The Spaniards go for the plug version, baionetas de 'taco'.
As plenty other weaponry over here, patterns found are massively Spanish, often comprehended as Iberian and little times specifically Portuguese ... the late obviously becoming rare, in ( at least) collecting terms.
This one is one of those Iberian riddles. Its style tends to be from Andalucia, on what touches blade and its peripheric works. However the handle, probably made in holm, has a German touch ( the spheric ferrule), which was a fashion practised by the Portuguese.
This is one of the most elegant pieces i ever found.
Hope you enjoy seeing it.
