1095 vs D2 is a choice between more toughness and more abrasive edge retention. Conventional D2 also resists corrosion better, although it still needs more care than many stainless steels. The useful question is whether you want a blade for repeated abrasive slicing or one where resistance to edge damage matters more.
Performance Ratings
For the science, we turn to Dr. Larrin Thomas of Knife Steel Nerds, who has kindly allowed us to share his ratings here.

Heat treatment, hardness and geometry affect actual knives.
D2 Has the Clear Wear Advantage
D2 rates 5 for abrasive edge retention, compared with 1095 at 1.5. For repeated cuts through abrasive material, we would favor D2 when the knives otherwise suit the job equally well. The scores are not a prediction of how many times longer one blade will cut.
This comparison uses conventional D2. CPM D2 is a different version, and a retailer listing that leaves out the CPM prefix should not be assumed to have its properties.

1095 Has More Toughness, but Design Still Matters
1095 rates 4.5 for toughness against D2 at 3.5. That favors 1095 when chipping resistance is more important than wear resistance, without making it an indestructible outdoor steel.
A thick D2 blade and a thin 1095 blade will not behave like identical test pieces. Compare the edge geometry and intended use before choosing a knife for more demanding work.

D2 Needs Care Too
D2’s corrosion rating is 4.5, while 1095 rates 0. You gain useful corrosion resistance with D2, but we would still clean and dry it after damp or salty use. 1095 calls for more attention to moisture and protective storage.
Neither name is a reason to leave a wet blade in its sheath. A coating changes which surfaces are exposed; it does not remove the need to care for the edge.
Choose Around Cutting and Maintenance
For package cutting and other wear-heavy slicing, D2 is the more appealing of these two. For a 1095 outdoor knife whose grind and handling fit your work, its toughness advantage may be more useful than D2’s wear resistance.
If you already own a good 1095 knife, consider whether frequent dulling is actually limiting you. Switching to D2 trades one set of strengths for another rather than improving every property.
