Stone seeker… you’re kidding…right?

No, don’t do that…

Very few razors are perfectly straight; just hone it with a rolling X.

You said you started honing on a 12k; had the bevel been previously set? It's quite normal, when dealing with secondhand, vintage razors for them to have all sorts of weird wear and/or dullness. You may find that the whole thing comes in pretty fast when you go down to a 1k to properly set the bevel. Or maybe not, and then you'll know what you actually need to play with. I don't think that a 12k takes metal off fast enough to give you an good idea of what's really going on. At least not for me.

I'm still learning, and trying not to have the wife's eyes pop out of her head when it comes to my new hobby's budget. So the only hone I have is a Shapton 12k M5 ceramic that was less than $50 on Amazon with free shipping.

This is my second razor in attempting my own honing (I dare not hone my Dovo from SRD). So slow was one of the objectives. If I would have started out on a proper bevel setting hone, I would have flown right by this issue in no time at all.

That, I think, would have left me at a deficit when figuring out what strokes were best for this blade's geometry.

[U]Update./U]
I got a bit tired with how long it was taking on the 12k. And the new strokes I was trying were having good results on the problem toe. So I replaced the layer of tape on the spine, got a 4x9" 2k w&d paper wet, slapped it on my marble tile normally used for lapping, and tried something new (to me).

Did Alex's pyramid, starting at 10 strokes instead of 20. Only light pressure on the problem area, at the edge. Did maybe two or three sets like that. Bamf! Almost completely set the bevel. Now I just need to play with the toe a tad bit more, and I'll be in business. I think. Then it really will only take an hour of polishing on the 12k .

Thoughts?

Dude buy a 4/8k Norton about 80 bucks.

If you are going to hone your own, you need some tools.

I have successfully straightened out several warped blade where parts weren't even touching the stone before i started. but yes i agree he shouldn't do it, its a very dangerous technique. and in this case it is not the problem

if you haven't set the bevel on the razor then that is your problem. you can send it out to somebody to hone it, then you can maintain the edge with your shapton 12k if you'd like. doing thousands of strokes on the your 12k can also help correct the bevel but its seems more reasonable to get a norton 4k/8k or naniwa 3k/8k

It looks to me like the stabilizer is hitting the stone. You can see a bright spot on it above the bevel on both sides. Unless your warp is really bad I wouldn't attempt to straighten it.

Either reshape the heal or blend the stabilizer with a dremel so it clears the stone while honing. Heal forward x strokes will get you around the problem too but it looks to me like it's time to fix it.
