[QUOTE=gssixgun;1477725]So many things come to mind



3. There is an over abundance of ignorant, inept, clueless, rank amateurs passing themselves off as "Restore Experts" all over Facebook and E-bay.. They are practicing with razors and then selling their mistakes so consider yourself warned

Great post Glen,Give me a buffer,give me the Buffing compounds,Give me a Dremel,I can make your blade look like brand new.
If I burn it up you will never know until you try to get a good edge on it

If the basic grind of the razor was messed up I would think that needs to be addressed first.

Based on the manufacturer stamp this is an old production razor.

You are saying that the edge crumbles during shaving and that likely means poor steel. You should calculate the bevel angle to make sure it is within the norms.

If the bevel angle is fine most likely there is nothing that can be done with the razor. It doesn't matter how even or uneven the grinding is the edge is not affected by the steel on the rest of the blade. As long as you can work around potential grinding issues and put a good edge on the razor it should shave, failing to do so means that either the steel is bad or the bevel angle is bad.

The later is trivial to check and relatively simple to work around, the first is unfixable (well you can try honing out say 1/16" of the blade in case the steel is better there but that's the only thing you can do at this point as the blade is already way too thin for another heat treatment cycle).

Kristian,

+1 on GSSixgun's suggestion of 'killing' the edge. Take the edge off the razor on the side of the Nainwa 1k. Tape razor, and set bevel on 1k. Do a Thumb Nail Test (TNT) and see if the edge is smooth on the nail - if not re-kill edge and repeat the bevel set until the edge is smooth on the nail for the 1k Naniwa. Take it up the stones and see if all is less bad.

I have an old Sheffield that took four (4) edge kills to cut off the 'bad' steel. After that it was fine

Have fun

Best regards
