Not speaking for others, but I can tell you that my fullsize Praetorian is actually pretty thin behind the edge. Sure, it's a huge foot-wide blade, but then, I'm not trying to slice tomatoes I can read through. I can cut food items, and open packages, slash cardboard boxes up, and snip threads just fine, same thing all my other knives can do. I think sometimes people get wrapped up in this "OMG it has to be slicey!" when really, they don't have any, or any often-recurring cutting tasks that would need a scalpel. If you need cuts of that level of precision, I mean, I wouldn't use a pocket knife anyway because a $4 Xacto knife is going to do that job better than any Opinel or PM2 would.
There was a thread awhile back from another user who showed pictures of all the things he had cut and they were cut just fine, and people STILL acted like he couldn't possibly have done those things with that knife because everyone "knows" that Medfords can't cut. (shrug)
