It seems like it's still a needed service, but yeah cutting tools are much more complex today and are mostly designed to last longer and be more disposable than they were in the '80s, manufacturing is mostly cheaper, and at the same time people have poorer manual skills.

But we also have the internet to figure out things we don't know.

I live near a metro area with roughly a quarter million people and everyone is pointing me back to exactly one shop, and apparently they are actually sending their work out to get done.

There is a small lawn mower repair shop close to me that volunteered to take a look. If they are handy they should be able to do it.

And also why does literally no one talk about opening up a side hustle sharpening business?
