The very point (Hee hee, I make punny) of most armor is to render bladed pointy things ineffective. I highly doubt the blades would've helped with piercing through armor and such.
The majority of combatants on any battlefield wore little in the way of rigid, metal armor because of how expensive it is. Those blades on the glandes would do VERY nasty things to those unlucky folks
Even in the late Renaissance when plate/mail armor was more-accessible than ever, the majority on the battlefield wore little to no armor aside from a simple helmet or so.
However, crushing blows ARE rather effective (varies a bit depending on the armor's rigidity, of course) at sending shock through armor without actually penetrating it. So even if it hit someone wearing metal lamellar/plate/lorica segmentata, it would still rain on the wearer's parade, if you know what I mean.
TL; DR Version:
These "winged" glandes would be devastating on light/unarmored targets, but they just wouldn't be any more effective against "heavy" armor than a standard biconical gland
BTW, hi guys! long time, no see
