Thread: What am I doing wrong to cause nicks in the strop?

Hey guys, what am I doing wrong that is causing nicks in the D-ring end of my Big Daddy strop?
I didn't get many in the past but lately I seem to see more. I sit when I strop and was wondering if I should stand or does it matter?
I am not going real fast either so that is not the cause as far as I know.
There are no nicks on the end connected to my bench.

Any suggestions would be appreciated. Thanks

Here is a picture of the damage:
