Thought so. I noticed a bit of uneven honewear on the spine. This is mainly caused by the fact that those sides are vertical.
If you angle them just a tiny bit inwards at the top (so the spine is a bit narrower at the top than where the hollow grinding ends) you can virtually eliminate that type of honewear.
This is because then, the ridge between the spine and the hollows is a bit sharper, and any wear will not spread out like it does now.
It really doesn't have to be much. Even a couple degrees will make a huge difference.
If you look at many older blades where the hollows don't end at the top of the spine, you'll notice the same thing. The place where the hollows meet the spine is the widest part, and all the rest is thinner. Sometimes only by a hair, but it is there if you look for it.
