Thank you, everyone, for the generosity of your time and expertise!
I love knives. I've had a set of Henkel 4 stars for about 35 yrs. Unfortunately they are still in perfect condition. I really want to dive head first into high carbon and super fine grain steels that are insanely sharpenable.
I would probably try a bench mounted dremel with a 1/2" round stone, stone, slow speed, water drip. But I'm just going to ease/smooth the shoulders of the spine and the back of the heel.
