It's another tool to have in your arsenal of honing options. But you have to be careful that you don't use it as a crutch like I did for a while. You can cheat your way to what feels like a shave ready edge by using diamond spray but it's never going to be great. I was convinced that the ONLY way to get a truly sharp edge was with a pasted strop. I was wrong and treated myself to a lot of harsh edges instead of working through my stones. If you're working with one good razor with a good edge on it, I'd say you don't NEED a pasted strop. I would opt for a 10k-12k stone and use it when necessary. When you inevitably end up with more razors and discover the individual challenges that each can present, then you may want to have another option at the ready.
