WW 1 was a period that was rife with ornamental edged weapons. Train conductors had very nice dress sabers. The Germans had (have) a number of fine swordsmiths who had Army contracts. Any one below the rank of general would have to have a sword that matched the others. Uniform, you know. I don't know if the Spanish were in WW 1 but the Portugese certainly were. There's a well known storey about a Portugese regiment and an assholey English general. Perhaps it's Portugese. As a small scale, would-be collector, I can assure you that it's a complicated subject, many were very similar.
