[Recommendation] Any isekai with the theme of having weak or lackluster skills but the skills are actually weak/lackluster

Basically the title, after seeing so many isekai manga with the title being kicked out/abandoned/disowned for having weak skill and then the skill is something like healing or blacksmith or tamer ( like super standard rpg skills) or some skill that has occurred the first time, or some skill that somehow has ability to do stuff that skill absolutely should not, my curiosity got piqued.

I know all of this basically Japanese salaryman fantasy of them being super competent at work if only their boss/colleague realized it but still is there any manga where the skill is something that would actually be considered weak, like in mistborn Brandon has some weak allomancy used amazingly, or something like nen chains where it is op but at like insane cost.
