Green paste is likely chromium oxide. You can use it on a strop to keep your edge in shape a fair bit longer. But don't do this unless you have an extra stop to sacrifice to the job. Once you paste a strop, it stays pasted and you can't unpaste it.
The other thing about CrO2 stropping is that while it keeps your blade shaving for longer, it also rounds the edge. This means it takes a bit more effort to hone when the time comes, and you are also therefore removing a bit more material to get that edge back in shape - although this arguably doesn't really matter. If you aren't honing yourself then it is no difference to you.
You can pick up a 'touch up' stone to keep your blade going for much, much longer - a Chinese 12k stone (very inexpensive), a barber's hone, a Belgian coticule, a Japanese Natural Stone (expensive),etc. Perhaps the easiest way is to grab a glass plate and some diamond lapping film. This is very effect stuff and the investment is negligible. However lapping film doesn't give you the same physical feedback, and therefore the same satisfaction, as a stone (I may be projecting my own preferences in there somewhere).
If you do decide to try any of these I would suggest grabbing a cheapo blade from the BST forums somewhere to practice on. Your custom sounds too nice to muck up with learning to hone. But really, with a little practice, honing isn't difficult. Much easier than kitchen knives ( I ended up getting an Edge Pro system because I don't trust my control to not muck up my any of my hocho), because razors have a built in angle guide that knives do not.
The only thing I don't understand is why we are still waiting to see a photo of your 7/8" Spanish Point..
... I love Spanish Points!
- I can't do slants, I find them far too aggressive. I tried one, twice
, and that was enough to make me give up. Of course my current DE of choice is a Fatboy dialed back to about '3', with a Feather in it.
h34r: So I may not be the most fearless shaver anymore when it comes to aggressive razors.
