Mirror finishes are sparkly, but what do they mean?
Think about this. . .a ball bearing can have a mirror finish. But it doesn't cut hair, or wood.
Bottom line. . .if it's good enough to cut wood to your satisfaction, then go make some saw dust, shavings, and chips. I've seen too many arguments all over the place about sharpening and razor sharpness and mirror finishes. It's exhausting to read. Old timers back in day didn't sharpen that well because time was money to them, yet they still produced awesome pieces.
At the end of the day, if your chisel/plane/steel cuts wood and does it satisfactorily. . .go with it.
