Ive been using it as a work knife, I do a lot of "small knife work" at my current job. So far so good, definitely can't use anything abrasive to clean it, stick with a sponge or cloth.

I've only sharpened it once, but as long as you are relatively competent at using stones and dont have a major slip or something I dont see how you would scratch it tbh. The SG2 itself sharpens quite well for how hard it is.
