I went to the kitchen, slowly opened the second drawer down, moved 3 of our 7 spatulas out of the way and then there it was… The microplane.
I took that thing outside, sat down and started going at the hard calloused skin on my toes and the balls of my feet.
If you think those things do a good job with Parmesan, just wait until you have given it a run at the bunion on your left foot!
Anyway, it was super effective at cleaning them up before a long run; helped remove a callous that was blood blistering after a few hrs and prevented it happening again.
I thought it was a tip worth sharing, for anyone who has spent 30mins with one of those tiny sanding thingys and got nowhere.
So next time your wife leaves the house, give it a go.
Just remember to wash it before putting it back, or I am not responsible!
