Connotation of あっし as a first-person pronoun


あっし is said by [imabi](https://www.imabi.net/pronounsii.htm) to be a 1. person
pronoun, derived ultimately from あたし・わたし and from the "working class dialect
of Tokyo Bay" (which presumably refers to 下町言葉).
[Wiktionary](https://en.wiktionary.org/wiki/%E3%81%82%E3%81%A3%E3%81%97)
claims it to be used by "dashing males and craftsmen." (which does sound quite
nice), but cites no source for this. So are these the actual connotations of
あっし? How common is it?
