I achieved the “I Sickle” achievement by harvesting a Shockbulb in First Light, and at the same time I apparently got the “How About I Swing By, Later On?” achievement at the same time, despite not being anywhere close to level 10 axe skill.
This occurred just a few minutes before I posted this topic.
Screenshots attached. Character name: Chartax
I’ve seen other people with this (and similar) achievements at levels they shouldn’t have been able to earn them so I’m guessing it’s not a one-off issue.
