So in the link provided, there are two YouTube videos embedded. The first is of a dude who is using denim to strop his cart - its short and includes close up photos of the blade before and after stropping.

The second is of some dude who gave up on his straight but is now marketing strops just for carts.

Its entertaining! For me, a straight guy, it was very entertaining!

Enjoy:
