unloved

I don't own any waved blades but you can get the idea here.
Personally, I find the Endura and Delica to be perfectly comfortable in all the grips pictured here. Your experience may vary of course, but if you ever actually need to use any of this stuff for real, I don't think you'll notice any discomfort.
