I adamantly dispute the notion that - in modern times, with top-quality steel and HT - "hollow-ground knives have a longer useful life because they can be sharpened more times, without getting back into thicker stock."
On the surface, this is true and logical. In decades past when most knives were made of steel with very low wear-resistance, at fairly low hardness (mid 50's Rc at best, in the case of most utility/kitchen/hunting knives), this was indeed an important factor (we've all seen old knives that have been sharpened so much that they're half their original width... overly-aggressive "sharpening" often plays a big role in that). They were soft and malleable, dulled easily, and had to be honed basically every time they were used.
I just don't think that's a valid argument anymore. Even low-alloy steels like 1095 that come from today's factories are commonly HT'ed at 58Rc or higher; in the custom/handmade world, that's a bare minimum. It takes a heckuva lot of sharpening to noticeably narrow down a blade made from any steel at 58-60Rc, and I don't know a single person who's actually done that in the course of many years of use.
Good, keen geometry from the get-go makes a knife cut well. Alloy selection and proper heat-treatment helps it cut well for a long time.
If you're honestly wearing down a FFG or full-convex blade by sharpening it so much that the edge is getting too thick, you either use your blade a whole lot more than anyone else in the current era, or you have a very soft knife.
