Hi, I've got a Wilkinson Sword Empire razor. No strop, two dull blades. I've also got (leftover from repairing a chair) lots of canvas webbing strap that's just the right size for a stop. If I paste up a short length of that with some #2000 or so lapping paste, another length #8000, will I be able to sharpen up these blades, or will I just round off the edge? Worth a try?
