Could it be because it is a wedge and the tape it self is causing the problem?

Should I try to hone it without tape?

Okay first you have to be WAY more detailed in your descriptions you have the first razor that looks to need about 3 layers of tape from the pic.. You are essentially using one right now, use the Sharpie Test to see where you are at, it works

The second razor needs the heel fixed FIRST

I don't actually know what razor you are working on using the trick I gave you, I think the first

Sharpie the edge, 3 light perfect laps each side, and show me pics

Are you using one hand while honing ???

Yes I am working in the razor in the first 2 pictures marked A & B.
I am using both hands while honing.

So I am on the same page sharpie the edge/bevel then 3 light perfect laps each side. with or with out tape?

When I get back to my bench tomorrow morning will get a Picture.

Thanks for the help!!

3 light laps each side one layer of tape

Add 3 layers of tape on top of the first correction strip, re-do the sharpie test
That is a HUGE bevel, it also means that the angle is off ie: pretty low.

Bevel size and angle are directly controlled by spine wear / edge damage a factory perfect Near wedge, to a Extra hollow all hone the same with a tiny even bevel at 16° -17°

Spine or edge damage over the years changes that,, Tape simply adds back the angle that the wear took away since welding on steel is impractical

Will give it a go in the morning.

Thanks again.

Done.

I'm probably overthinking this but, when I get vintage razors they often have hone wear.
I doubt anyone taped the spine 150 odd years ago.
What I do wonder about is how our razors will look in 150 years from now, we tape the spine so there is no spine wear. If we hone with tape for 150 years will the blade just get narrower and narrower, and the bevel angle must change a lot after honing with tape for over 100 years.

I'm not saying I don't use tape because I do (Kapton) but it's just one of the things that go through my head when I can't sleep.

If the the bevel angle is controlled by the spine and the height if the blade and we remove steel when we hone then the bevel angle will change over time as the blade height changes.

Just you give you more to think about when you can't sleep.

So now the question is when the spine wears it narrows and the blades height shortens given all this happens evenly (we know it dose not) then the bevel angle should stay the same for a longer period of time?

“the bevel angle must change a lot after honing with tape for over 100 years.”

No, most of my personal razors will only have a full bevel set on a 1k, once as long as I own them. Most pro honed razors have a minimum of steel removed, most I set the bevels with a 4k.

My razors get an 8k reset or low grit nagura.

The tape improved the bevel, if you want an even bevel you will need to sand and buff off the bevel then reset. All the tape did was make up for lost and uneven steel. You are not rolling enough to hone the toe and edge.

The toe will get a sharp corner and will shave fine but look funky and the heel also will get sharp it is already developing a corner. A few strokes will reprofile them. I would make it more of a smiler.

When you use tape, make sure it is on tight and flat, stretching it a bit helps. Looks like you have a couple bubbles. 3 layers can get squishy and cause wonky bevels. If it feels squishy, replace the tape. A layer of Kapton over electrical will make your tape last longer and glide easier.

Here is a good video of Charlie Lewis doing a Rolling X. Notice how the heel does not fall off the stone. Ink will tell you how much you need to roll. I use ink on almost every razor. It will save you time and steel.

So sand the bevel out right down to the edge?
I had the same troubles with the heal the first try but only on one side. this latest one was 3 strokes on each side and it never touched the heal on that same side.

There are no bubbles what you may be seeing is the correction tape showing through.

I will order some Kapton
