Depends how handy you are
But it takes some time to develop the right muscle memory on different type of hones to keep the razor flat on the hone and avoiding too much pressure. (I know I still have to be very aware of the pressure used)
It takes time to develop the stroke that gives you good results, we all have our specific way, the main motion is the same, how we apply it is a subjective thing.
Did and do I consider myself handy and quickly acquainted with new skills? yes
Was only refreshing a razor that difficult to master? Nope
Do you know how to really hone a razor? Nah
Things start to become difficult and challenging when honing different and troublesome razors, they're still a huge PITA and I don't like it when I can't get them 100% right, it takes time and trial and error to figure them out.
I can't be the only one to have ruined a few razors in the process.
During that period we look for and create a specific way of honing, different types of strokes, using tape or no tape, different hones, edge tests, honing gymnastics, etc.
Learning to hone my own razors was never a question, I had to be able to do it, I can imagine many guys sharing this sentiment.
What I have noticed is that I always keep learning more things about honing razors. You always stumble upon new challenges when buying old blades.
That said, as with anything, get the right tools, get the right philosophy combine it with a good dexterity and you're off; then experience and honing a lot of razors is the only thing that will make you good at honing.
The fun part is that you can choose what edge you put on your tools. If I didn't start honing my own razors I probably would've quitted SR shaving a long time ago because of unsatisfying edges / shaves.
(It took a LONG time to learn how to actually shave well with an SR and shaving with somewhat subpar edges made my technique better because I had to be really careful and figure out the most skin friendly way to shave whilst giving a close shave)
OTOH, it's not rocket science, I would encourage everyone to give it a go. There's enough great guys and knowledge floating around on here you can easily be prepared and get going.
I know I wouldn't have figured it out all by myself, I didn't get the knowledge about straight razors passed down to me by my father or grandfather, so thank you cyberspace!
