Some good information so far. Personally if I was going to by one stone I would buy the Norton 4k/8k The 8k is a fine hone to use for refreshing the edge. As to paste
http://straightrazorpalace.com/strop...ugh-guide.html I did this post awhile ago and I find paste to be a reliable method for everything up to setting the bevel. Setting the bevel can be done with paste but is a real pain in the butt. The major benefit for a new shaver is that pasted strops use a skill that you are already developing and using everyday stropping. If you do use a pasted strop use a paddle strop it eliminates a lot of factors.
