My results with taping all of the razors I hone has been the opposite of Dave's. Mine are shaving quite nicely. I am glad that Dave posted that taping spines is stupid and there is no reason to do it. Perhaps now Tim Zowada may learn the error of his honing technique. As for me, I'm going to keep taping spines with the one layer of 3M. It's working so I needn't fix it.
