Bread knife recommendations?

I just posted about this in c/sourdough but I thought maybe some of you would have opinions and suggestions too. I’m not sure the etiquette around this kind of thing so feel free to scold me or just ignore the post.

So: I think my bread knife may have become too dull to use. It won’t slice through the crust on my sourdough and I end up hacking it to very uneven pieces. And I’m afraid I’m going to cut myself. Any suggestions for a new bread knife? Is there a big difference between the really cheap ones and something more expensive? Thanks!
