For a real "first time" user the only suggestion I'd add to this A+ advice is to pick up a cheap set of chisels (&/or carving set). Cheap as in lowest price, quality isn't really critical at this moment. (Harbor Freight, Amazon, etc). This way you can practice sharpening, grind a new base bevel angle, then try wet sanding on glass. You can explore processes & develop your own preferred methods all while having zero worries about messing up your expensive $ quality metal. This is prolly even more appropriate if your aspirations include carving & whittling blades because there are so many different types - unlike the general similarity found from one chisel to the next with only the blade width being different. TLDR: the advantage of having a sacrificial set of chisels/knives stems from being able to continually practice as often as desired & gaining muscle memory etc. thru repetition vs the inexperience resulting from infrequent opportunities coupled with the stress of not wanting to mess up new expensive metal.
