I will be working with 1/3/8K stones to set the bevel and hone about 10 antique store SRs. I don't see myself getting into the honing business...so my honing work will be just for my personal razors.

I am trying to keep a minimal kit for sharpening my razors. I am not into procuring a large stock of sharpening tools

Do I need a lapping/flattening stone? If so, can you recommend a reasonably priced stone?
