Thread: How do I fix a weak wide bevel/fin?

Like the title indicates, I have a razor that has a weak and wide bevel. Probably from overhoning causing too thin of material at the apex causing a fin/burr. This is my practice/experiment blade. I noticed that even if I would use the lightest of pressure the apex would still get pressed out of the way and not touch the stone. I added tape and it allowed me to reach the apex, but I am hoping to not have to use tape. Nothing wrong with it I just don't prefer it. any ideas as to how I can get down to better metal and thin out the width of my bevel?

More details and images as to my issue is found here http://straightrazorpalace.com/advan...-get-line.html

When you honed the blade after adding tape did you notice if you have a two part bevel? The upper part from honing with no tape and a lower part down to the edge after honing with tape.

Yes. That is exactly what I see; a little micro bevel.

If you have lots of hone wear on the spine I think you will have to use tape, maybe even several layers. That's just the way it is with a worn spine.

Add one more layer of tape and see what happens. If you can post pics of what the bevels look like now, it will be very helpful.

Take everything I am about to say with a grain of salt, not being an expert on honing myself.

OK, that is normal under the circumstances. Some people actually set a micro bevel as their normal way of doing things, usually on the finishing hone by adding a layer of tape then. It should shave with a micro bevel set.

How many layers of tape did you use? I did not see a pic of the blade overall so I was wondering how much hone wear there is on the spine. You can use layers of tape to compensate for excessive hone wear and by doing so you will get a smaller bevel than without using tape. You can see the difference in size between your normal bevel without tape and the micro bevel with tape. If you want to keep the small micro bevel size you have to keep using tape or you will be back to the wider bevel.

If you do have a wire edge a couple of back strokes, spine leading instead of the edge, might take care of that followed by a couple of very light normal strokes.

You might try measuring the blade and seeing what the bevel angle is. If it's in the normal 17 degree range (say 15-20) then the angle is likely not the issue. That's not to say the steel plus the angle is good ...

Usually fin edges are caused by too much pressure, an aggressive stone, or both. If you're using the lightest pressure, you might try a less aggressive stone. Might also try some circles and ellipses just to see if they give any different results.

If you have a coticule or a Jnat laying around, give them a whirl. If you want me to see if I get the fin on a Jnat, shoot me a PM and we can meet up.

Good luck! Steve

Here is some pics as requested



Now as to the included angle, I'm at 16.0°. Now I do know that I was using too much pressure during the bevel set. I'm still learning and that is one of the things I learned last weekend using the microscope.

Also check it for a frown, I'm not sure if I'm seeing one or not.

The white line that I see in the pics, where the apex is, is unset bevel IMO.
Just keep on working at it till the line is gone.
