Good slicers. They tend to cut very well because the blade is thin. My No8 (blade length of about 3.25") has a blade thickness of 0.07" (about 1.8mm). Most anything "tactical" is going to have a blade spine thickness of 3mm or greater these days. For a rough comparison, you can think of it as being somewhat comparable to a Swiss Army Knife blade although without the taper you see on the spine of a SAK where it gradually thins toward the tip.
The blade on mine is stainless and it holds its edge pretty well for the use I put it to. I don't (and wouldn't) use it for hard duty since the blade is not especially robust. I don't consider that a criticism, not all knives need to have thick blades, people just need to understand the functional difference and realize that what might be acceptable with a thick blade is ill-advised abuse with a thinner blade.
There's a temptation to assume that because of the cost and simplicity that they're "cheap" but they're actually good quality.
The handles are mostly round and indexing is based on the end of the handle where there's a flare and the handle cross section becomes more oval. If you get a larger model, you'll be mostly holding a round piece of wood because the back of the handle that helps with indexing is too far back to get a grip on. But if you stick with a model that has a handle close to the length of your hand, it works pretty well. The No8 I have has a handle length that is almost too small for my hand, but that puts the flare at the end of the handle where it helps index the knife.
The handles are untextured so they're not especially grippy. That can be fixed if you're inclined to modify the knife.
There is nothing keeping your fingers off the blade, no guard or choil--the blade is sharpened all the way to the back where it meets the handle. If you tend to grip the knife near the very front of the handle and crowd the blade when using a knife, you'll learn your lesson pretty quickly.
The lock on the locking models is very positive in both open and closed position. One handed opening is iffy unless the pivot is on the loose side. Mine isn't really tight so I can unlock it with one hand, flip it open and then lock it open. They can be unlocked, closed and locked closed one handed with no problem.
