would you guys suggest that a magnifyer of some sort is really helpful to a new honer? wondering if it will show me my mistakes, or if they arent worth it. and if you think they are , has anybody used the cheapies on amazon? are they complete garbage or will they work decent. also i was wondering if anybody has ever posted any pictures (like a series through grit progressions) of what they should look like ? sorry that was alot there.
