I am very new to straight razors. My first good quality razor (DOVO) is in the mail right now. Previously i had a crappy eBay Pakistani blade. I have been reading a ton on this site and absolutely love how helpful everyone is.

But i have a question regarding hones. As i have purchased a shaveready Dovo from SRD i wont need to touch it up for a few months (according to what i have read) but when that time comes. What type of stone should i purchase? I have been looking into a norton stone and cant decide if i should get the 4000/8000 combo or just an 8000. Will i need the 4000 side to "touch up" my blade every so often? How much should i pay for a hone?

Any advice is appreciated. Thanks
