Unless they get damaged sharpening once you know how to do it should take a few minutes at the most each time.
Cutting edges I use a lot need sharpening frequently, sometimes more than once a week, and it takes next to no time to grab the right stone or steel and restore the edge. I’ve never bought or even used a mechanical gadget.
Even badly chipped edges can be resharpened in a few minutes. It’s a skill worth learning if your trade depends on cutting things.
