For slicing, it's hard to beat the main blade on any Swiss Army Knife. They got it right decades ago, and never needed to change it.
But to be frank and honest, most any traditional knife has a great blade or blades. These days the focus with knives is all about big, heavy duty knives. Hard use. Folding prybars. The focus seems to be on what the knife can take, rather what the knife can actually do. I used to carry big "tactical" folding knives. Spyderco Military, Benchmade 710, Severtech (now that's a brick). It's my turn in the ZT 0560 passaround. It's a great knife. But it's way more than I need. At work, my hat had a loose bit of thread on the brim that was bugging me because it was in my line of vision, so I whipped out the 0560 to trim it off. It felt ridiculous. I sliced open some boxes from the side with it, and it was far less efficient than the Hayn' Helper sheepsfoot jack I've been carrying. The thick(er) blade just didn't glide through the cardboard like a thin blade will, despite being armhair-shaving sharp.
I don't mean to toot my own horn, but at my young age, I'm glad I've wisened up. I used to carry certain knives because I thought they were cool, not because they fit my needs. I still own and carry modern knives. Primarily a BM 940D2CF and a Spyderco Caly 3. They're slicers. I don't need a folding prybar. I don't need a blade that feels like a folding machete. I get far more use out of a 2-4 blade traditional knife than I do a big honkin' tactical.
Now, I'm not saying that just because I don't have a use for thick bladed, bank-vault lockup tactical knives that other people don't. I'm just saying that people that carry those, but have never carried a SAK or a Schrade 34OT or a Case Peanut, are missing out and don't understand how useful a thin, smaller, more controllable blade can be.
