Hello Everyone from Canada

I have just joined SRP and from what I have been reading the members sound like they have a wealth of experience that I could use. I have purchased a straight razor form e-bay with little knowledge about them but fully intending to use it to shave with. I is in pretty good condition but could stand to be polished and honed so that I may be able to use it for shaving. I have tumbler but have yet to find the walnut and corn cob media to tumble the razor with. Any sources for these media?
