Yes, please do watch Nick Wheeler's videos. Aaron Gough I think has made some too, IIRC. To sum it up....you need to go thru a grit progression with wet/dry sandpaper and then polish. Like 120, 200, 400, 600, 800, 1200, 1500, 2000, 2500. You always alternate the scratch pattern direction when you change grit. And use a firm sanding stick with the paper wrapped tightly (not loose). For a true mirror finish, you need to go as high in grit as you can. Even after that, you'll have to polish out the scratches. They (mirror) finishes are extremely time consuming, difficult (very difficult in my opinion), and get scuffed easily. But done right, they look awesome. I like the looks of a satin flat with a mirror bevel. Like Rockstead does on their knives.
