What are the advantages of D2 for knives. I've heard good and bad. Just looking for a few more opinions.

I love it. great edges and holds them very well. If you work at it they shine up. Semi stainless. I have used mine to cut 16 peeny nails in half wil little or no damage. I place the nail on a piece of aluminum and then hammered the spine a couple times on a shaving sharp edge against the nail. Cut them right in half. Down side is very little flex before you have a broken blade. D2 makes a poor pry bar.
 
High carbide content = good abrasion resistance

Micro serration effect from carbide aids cutting hide and hair, so it makes a good skinning knife, but a poor straight razor (CPM D2 is a different story)

D2 is a great steel.

Nathan, by your comment, looks like you have had some experience with the CPMD2. I use D2 but have never tried the CPM version. Would you care to comment on the advantages of the CPM?

I don't. I have not used CPM D2. But one of the main purposes behind it is the smaller finer carbides. Conventional wisdom says D2 makes a poor straight razor because the big nasty carbides, but that is not the case with the CPM version. People do use CPM D2 for straight razors.

I have made blades in D2 that were so thin they sung on the strop, and so fine they'll cleave a dropped grape. But I wouldn't want to shave my face with one. I do like using one to skin a deer though. I like the big nasty carbides for that.
 
I'm still working on my second knife out of o1 but my next one will be d2.
