S30V - Great for sharpening and difficult to corrode. Expensive.
Carbon - Great steel for sharpening. They rust easily. Inexpensive, and you can find high-carbon steel in abundance at any flea market/junk shop in the form of files.
Stainless - Not great for sharpening and difficult to get a decent edge.
Sharpening is an art for sure, but one of the easiest arts to master. Tips:
A stone to sharpen with (Diamond Hones or Double sided course/fine, )

Paul Sellers is pretty well the easiest and least expensive method to get a super sharp blade. With a $20 set of Diamond Hones you can take anything from dull to super sharp in a few minutes.
Patrick Roehrman’s “Beyond Razor Sharp How to sharpen almost anything.” is a mighty valuable video to describe the theory and a good resource for beginners to become great.

My other recommendation is Murray Carter Blade Sharpening Fundamentals.
