Sure I would. Most of my custom fixed blades are D2, but the only folder I have with it is the KHnutbuster in my avatar. If more production companies offered it I would have more.
Its has good corrosion resistance, and is as close to a stainless as you can get without being one. Its about as corrosion resistent as the stainless ATS-34.
I have no problem sharpening it, and find its easier than most of todays super steels. Takes and holds a great edge, and keeps a good working edge for a good while. I use a slightly toothy medium edge on my hunting knives, and D2 does very well with a medium edge
I treat mine like I do my stainless, and have never had a problem with rust. I oil all of my knives now and then.
