Welcome to SRP, Danny.
It looks like a nice blade and a good score.
It seems that you have the right idea to get it honed through the classifieds here.
I can tell you from experience that you need a baseline to compare with.
The learning curve is huge and we look forward to assisting you with your journey into straight shaving.
IMHO the hones that you use for your chisels etc would be too course to hone straight razors.
My advice to you would be to spend time looking at the WIKI - it is time well spent IME.
Most of all - enjoy the ride.
Cheers,
Geoff
