Any abrasive at 0.5 micron is going to remove more metal than you want if used daily. I think some people are maintaining their razors nearly indefinitely using 0.1 micron abrasives. You might need more laps using iron oxide than CBN or diamond, but it should work without removing an excessive amount of metal unless you are really going overboard with the laps.Thanks, that's a really detailed explanation.
Given that iron oxide appears to be finer and softer than CrOx, is it possible to use it for daily stropping? Daily stropping with CrOx weakens the edge (I think?) so is the risk the same with iron oxide assuming 50 laps or so in between shaves?
Since iron oxide is softer and finer, is it wise to put the paste on the other side of one's regular strop, since contamination would not -in theory- be as detrimental than if CrOx was the contaminant?
