All of HH's points above^ are on the mark. :thumbup:
Might sound counterintuitive, but when I thinned the cutting geometry of my own knives for such uses, the dulling of the edge on the plate became less of an issue. Reason is, when the cutting geometry becomes thin enough to greatly reduce the pressure needed to cut a steak, there's no longer any need to drive the edge so hard into the plate. So, the lighter the contact with the plate, the less damage will be done.
My Dad always halves an apple on the ceramic tile countertop, using a paring knife. He'd 'hinted' some time back, he wouldn't mind if the knife were sharpened a bit. I did that for him, and the first 3/8" of the edge near the tip was flattened again upon his first use of the knife (cutting an apple on the countertop). I kept fixing it for a while, then just decided to let that flattened portion be. The rest of the edge is still plenty sharp enough to get the job done.
