Thread: "Sharpness" - is it a bevel issue?

The last three pictures are with the edge leading AWAY from me on the stones. There is a marked difference between the two sets of pictures, particularly towards the toe of the razor. I actually noticed this halfway through my honing session and tried to correct it, tried to make sure the strokes towards and away were perfectly equal in pressure, length and type of stroke. Unsure why I have this problem.
One possible reason, is that I notice that I do circles the "wrong way" going up the hone, as my muscles automatically do it anticlockwise motions up and down the hone, rather than reversing direction. I tried correcting for that in the second half of my honing session and made myself do clockwise circles up the hone (away from me), but to no avail.

Help gratefully appreciated. It is frustrating because the first set of three pics are quite pretty!!! As above, heel first then middle then toe (in order of worsening bevel!!)

Alcohol will remove the permanent marker. I often use aftershave to remove marks after the test shave just because it's handy.

worked a charm thanks.

any ideas on the loss of bevel towards the middle and toe of razor on the away stroke??

Yes

Sharpness is all in the bevel set... So much so that you should actually get a pretty good shave off of just that




Yes it is true

These actual shave tests at each level will teach you quite a bit about your Honing abilities or lack thereof
Try a shave at each level and learn things

Thanks Glen, as soon as I get the pictures looking pretty then I would be happy to trial a shave off the 1k then work my way up!

Most likely a result of uneven blade grind - a fairly common issue, especially with older razors. Other than aesthetics, it doesn't hurt anything as long as there is visible bevel on each side and no dips in the edge.

Should add that this can also be caused by a warped blade, although that will show corresponding changes in bevel width on both sides. See this article from the SRP Library:

Bevel-setting in theory and practice - Straight Razor Place Library

Sunday afternoon treat to myself. Sat down with the football on the radio and tried again, including a shave test.

As per the last attempt:
1. Stones flattened
2. Razor taped with one layer and dulled on glass
3. Toe leading x strokes only no circling.

Pictures and shave test are after 1k then 3k without stropping.

The razor shaved smoothly. I used it to pass down my face on the cheeks only. I have a pretty sensitive neck and didn't trust it to go onto my neck. There was no pulling, no grabbing, it just took away the hair.

As per the last attempt, I was having trouble with the toe of the razor. despite it looking like the water was being pushed away from the edge uniformly, the magic marker took longer to disappear from the toe of the razor, that part of the razor took longer to pick up leg hair, and under the USB scope that part of the blade still is a markedly narrower bevel compared with the centre of the blade.

I will finish this razor to 8k then JNAT just to see what it feels like going all the way up the progression, but will dull it and drop back down to 1k after that to practice and learn based on comments! Photos are a random three from either side up and down the blade, I honest can't remember which is which. The one which is markedly narrower is the toe!!!
Thank you for your input.

So, all three photos are the bevel at 3k?

If so, you still have a lot of 1k stria, it does not look like you are honing to the edge, and the bevel is not fully set.

That bevel looks very damaged and may not hold an edge, at the least, you will have to get past the pitting on the bevel. Joint or lightly bread knife the edge, until you are well past the pitting and into good steel, it should only take a few swipes on a low grit stone or diamond plate, the edge is very thin.

Also take your photos so the edge is facing the same direction, it makes it much easier to determine what we are seeing. In the 2nd photo is the narrow, blurry band the bevel?

I suspect you are not using enough pressure on the 1k to grind the bevel flat and reach the edge. At 1k, the goal is to grind the bevels flat and into a single plane, it appears you have not accomplished that. Sometimes you have to use more pressure, especially when making corrections.

Using too much pressure can cause chipping, but that can be dealt with simply, by jointing the edge and resetting the bevel with less pressure. Try using 2 layers of tape to increase the angle and see if that reaches the edge, you can always drop back down to a single layer and reset the angle in a handful of laps later if you wish.

Watch your tape when using pressure on a low grit stone, it is easy to burn through the tape. Keep inking the bevel to see your progress, colored ink makes it easier to see, black ink can look like a shadow. Tape and ink are cheap…

That the ink was difficult to remove, is a good indicator that the bevels are not flat and in a single plane, and most probably the swarf remove the ink, not the hone. All your ink should come off the bevel completely in 2-3 laps, once the bevels are flat, though that does not mean that the bevels are meeting. Look straight down on the edge, if you see shiny reflections, the bevel is still not meeting, fully.

The bevels can be flat, at the proper angle and still not meeting fully. You have to achieve all three, to fully set the bevel.

Lastly, once you set a bevel, killing it and re-setting it does not really teach you a lot about honing, because 95 percent of honing is flattening the bevel, setting the angle and getting them to meet,(setting the bevel). Once you have accomplished the first two, getting them to meet again, after jointing is simply a matter of a few strokes, all the hard work and learning is already done.

Thank you.
Yes all three are at 3K. Will ensure all photos are the correct way around next time.
Do you see pitting anywhere except in the first photo? That may be alcohol wipe to remove the magic marker pen.

In terms of ink removal, I get ink removed all along the cutting edge within a few laps with the exception of the toe, both on this razor and on the razor I was practicing on last week. The toe is problematic from a magic marker removal perspective. I use two hands to make sure the whole blade is on the stone, and lead with the toe for my strokes.

Thankfully tomorrow is a bank holiday in the UK, so will go back to the 1K stone and try again with more pressure.

Shame, because it felt relatively ok on the face this afternoon!
