It also seems like there is a lot of convenience in sharpening knives with thin geometry. I could be misunderstanding, but if it is easier, quicker, more forgiving to sharpen, and increases the longevity of an edge in several ways, I think that's a huge advantage and attractive feature of thinner geometry.
I guess BBB has corrupted me!
Huh I haven't thought about it much, but my kitchen knives sharpen really quickly compared to my utility knives. I supposed it's just that there's not much metal to take off from their super thin edges.
That's a nice advantage.
I wonder if the average spyderco customer actually sharpens their knives though.
Thats a good point and, actually, is one thing I think thinner geometries are good for.
Even if the edge is dull by our standards, thin knives will require less force to separate materials. If paired with hard steels that are strong and stable at the edge, they will just get less dull over long periods of time.
In my experience, Spy27 and CPM15V have just been blunting rather rolling or chipping. I think this less minor deformation (up to a point when talking strength over toughness), coupled with an edge that abrades less, means it just takes longer for the apex to wear into a thicker geometry near the very apex.
I think, according to my understanding at least, that is where the most significant increase in performance lies with thinner geometries and steels which support it for the '"average knife user".
I brought this post from BBB up in another thread today, but I think it illustrates some of this well and is also relevant here.

Also, just to clarify, I don't mean anything extremely thin or that every knife is too thick. That Military was probably just right for the guy using it and the right geometry for the model. I only think some models, or even a new model, could be a little thinner.
I like to chase performance, but I don't always keep my knives perfectly sharp and sometimes find uses that will abrade any edge past acceptable sharpness quickly and then still need my knife to cut reasonably well, so I happen to be in the right position to appreciate a lot of the different performance advantages these things bring that different kinds of users will appreciate. That gives some insight into one of the reasons I often like serrations too.
rex121 is the king of steel, but nature’s teeth have been cutting for hundreds of millions of years and counting :cool:
