Here's something I really love... thinner edges... ie. thickness measured behind the edge bevel. This can be a bit mucky trying to sort out because you must compare apples to apples, meaning the edge bevels must be the same measured angles from one knife to another. Here's a couple of knives that I've just reprofiled to a measured 15 degree per side edge. The difference between the two is quite dramatic and you could argue one is heavily overbuilt.
The first is a Busse Battle Grade Urban Grudge and the second is the new Bad Rattitude. Both were unused with factory bevels when I received them, so they should be considered representative for the most part. Note the extreme difference in the width of the edge bevels between the two. The wider the bevel is the thicker the measurement will be directly behind the edge bevel where it meets the primary grind.
I don't have calipers but a difference so large hardly needs them to tell the BG UG is obscenely thick compared to the lean Bad Rattitude which carries it's thinness all the way to the tip. I would estimate it to be at least twice the thickness behind the edge. It's also worth noting these blades are identical in blade length and of a similar thickness. BG UG has 5 degree primary bevel and the Rattitude is 3 degree bevel. So they are quite comparable in most ways overall.
Also worth noting that I did not significantly overgrind either of these blades. I removed just enough metal to get the new bevels to go all the way to form an apex. That can also be a factor as I could easily grind the Bad Rattitude edge bevel much more to thicken it up where it meets the primary grind. This can easily happen with powered equipment if one is not being careful to grind slowly and deliberately removing metal only where it's needed and not other spots.
