Welcome to SRP.
I would suggest you get the razor honed.
I know of two people in the UK who offer a honing service. One goes by the name of Poona (?) who is based in Belfast and another guy who can be contacted at www.theinvisibleedge.co.uk
There may be others, might be worth having a look about.

Both are members on the forum and will be able to hone your razor. Once honed, you will be able to keep it sharp with the gear you have.
