If using a spanner on a hexagonal wheel nut, use the copper end. If working directly on 2 or 3 eared spinners, use the hide end, to avoid damage to the spinner.
Agree
I once used the copper side directly on a spinner on my first Mog and regretted it as it put a dent in the spinner. It didn’t look terrible but I knew it was there
There are some rubber hammers available that have weights inside the head which give some extra power. A few Mog owners swear by them. Budster recons these are quite a bit better than the traditional copper/leather hammer
