Being it's a registry does change how you may want to approach this.
Also being it's at a retail store that will issue credit for anything you return that can then be used for whatever you like adds yet another dimension.
I am not going to advise on what to include on the list because any time I have for family or friends in the past the result was not positive lol, but the idea of listing items you may not intend on keeping is not original by any means
But that's all up to you etc.
I didn't mean to sway you away from the fibrox, and was using the lower price point as an option to allow more funds to be available for the main knife etc and will add many do find them a good value.
I also had included the two Japanese brands for you to check out as they do seem to be on everyone's list for best budget etc and are also ones I have experience with and were also part of my first j knive purchase.
Oddly the choice between the two for a gyuto is a tough one for me because I prefer the feel and using the Fujiwara, but still prefer the VG10 steel used in the Tojiro, and it becomes a matter of personal choice or preference etc. I also know it's not easy to have a preference between two items that you can only actually handle one of lol.
If your stuck with what is avail at the specific store that will reduce your options while also helping you to make a decision easier because of the same limitations. So both good and bad.
Sharpening stones are an entire separate topic, and for me at least required as much investigating as my knife purchase.
Since they vary in price almost as much as the knives a budget range would be required as well as an idea of any experience with sharpening, and more.
Take a look at some of the previous threads on stones and suggestions etc and see what you think, and get back with the answers to the above, and any new questions.
I may not be the best for answering those questions but expect we will see some others chime in.
