Sharpening the 630? Help!

Cliff, it looks like I am hitting the edge as the marker is removed, but still no real sharpness.
It could be a steel problem, it happens on rare occasions, someone has to be the lucky one. Email sent.

I've had three 630's and every one had as sharp an edge as you could ask for. Not that that has any bearing here. I would take Cliff up on his offer. If it can be sharpened, I would think Cliff can do it. Plus, it is a mighty kind and generous offer to do so!! :D :cool: :D

p.s. just tell Cliff it don't need no testing..... :eek: ;) :)
 
If anyone is curious, the knife refused to sharpen because the steel has severe problems.

When the spyderco rods are used, even on the flats of the whites with light pressure, the edge explodes with chips the size of an 80 grit AO belt finish.

I tried waterstones and they didn't help, I could not go light enough to preserve the edge and get them to cut.

I achieved a decent shaving edge with a 1200 grit DMT stone and CrO buffing, however while it shaves, it won't float hair or cut tissue paper and the large chips are still there.

The knife feels like glass on the rods, it acts like untempered steel. Benchmade likely blew the heat treat on this one.
