Glen I think he just cut off the tip up to the crack, the razor is just shorter. That probably will still change the feel but nit as much as making the razor narrower imo.

I don't see a reason for this razor to not be able to take an edge.

I'd like to see pics

You mean like hone until the crack is gone?
That will take forever and your razor will turn to 3/8 from 5/8(assuming yours is 5/8)
You can just trash it or cut it, I have no other ideas, may be...

If you want to remove the crack as stated by Olivia, you need to regrind the razor.
I am dealing with similar situation and will go for it just for the eperience of it.
