When I started straight shaving I tended to put too much pressure on the spine as I stropped. I have quite good coordination, so I avoided the usual strop-nicking issues, but I'm sure the pressure use was detrimental to the edges on my razors.

One of my main pitfalls was not ignoring the urge to test the edges.

I destroyed the edge on one razor by doing the TNT ------ not recommended for shave-ready straights.
