So, I just ground down that peak spine so it doesn't poke my palm as I go and close the knife, I measure at the peak and it was about 0.025" and now after hand sanding using diamond stones and 600 grit sand paper, it's about 0.043" but the main thing is the pointy peak isn't there to jab, again not a jab jab kind of thing but for me, a nuisance. And as I can pinch grip the blade to open the knife, that portion is a bevel and does not come into play when pinching the blade so it did not lessen the ability to grip it to open.
To keep it perpendicular to the spine, I laid the blade on a riser and set the diamond plate flat on the surface and proceeded to abrade the peak down using that setup, I would flip the stone over to get a fresh area as well as putting different blocks under the blade so I can keep using fresh areas of the diamond plate.

Yep, not the same as new, but for me, I'm liking it better without that peak spot on the spine
