1095 and 5160 are both non-stainless steels, but they are not interchangeable choices for a large outdoor knife. In Dr. Larrin Thomas’s ratings, 5160 has much higher toughness while both receive the same abrasive edge-retention score. If you are comparing blades for demanding cutting, that difference deserves more attention than the familiar carbon-steel label.
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.
The Main Difference Is Resistance to Chipping
5160 rates 9.5 for toughness against 1095 at 4.5. We would give 5160 the advantage when resistance to cracks and chips is the priority, provided the knife itself is designed for the work. A high steel rating does not make a thin tip suitable for twisting or prying.
For controlled slicing and carving, the toughness gap may matter less than how the edge is ground. A well-made 1095 knife can be entirely appropriate for that work without matching 5160’s score.

Neither Has an Edge-Retention Advantage in This Chart
Both steels rate 1.5 for abrasive edge retention. That rules out a simple claim that 1095’s higher carbon content means it will keep cutting longer. Heat treatment, edge angle and the material being cut still influence the result.
We would plan on regular edge maintenance with either steel during abrasive work. The equal rating also does not promise identical sharpening time; the amount of damage and the size of the bevel matter.

Both Need Rust Care
The corrosion ratings are 0 for 1095 and 0.5 for 5160. That small difference does not turn 5160 into a low-maintenance stainless option. Wipe the blade after wet use, dry it before storage and use an appropriate protective treatment when needed.
A coating can help on the covered faces, but the exposed edge and any worn areas still need attention. For food use, choose a protective product intended for food contact.
Which Would We Choose?
For a knife intended for demanding outdoor cutting, we would lean toward 5160 for its toughness margin. For a smaller 1095 knife with a comfortable handle and a useful grind, there is no reason to reject it just because 5160 wins that property.
If avoiding rust maintenance is your main goal, neither steel resolves that concern. Choose the whole knife around your work rather than treating this comparison as a universal winner.
