Thread: When is hone wear bad?

One of the razors I was recently given very clearly saw years of heavy use by the former user--the spine shows very wide, flat wear (I think you can see it in the picture below). The razor is a near-wedge, and I'm wondering if this hone wear would be detrimental to the razor's performance.

I assume that excessive hone wear would make honing an issue due to the change of the angle, but is it a serious problem? If so, is there anything to be done to counter it? Taping, perhaps?

The wear is even across the length of the razor, though it doesn't look it in the picture.

Thanks for any advice!

IMHO hone wear can be considered "excessive" when:

1. The bevel and/or spine start to invade the etching, engraving or stamp on the belly of the blade
2. The spine wear causes there to be a sharp edge on the ridge of the spine like a skate blade. This can be dangerous. I've actually sliced one of my nice bathroom towels with a razor like this.
3. The wear is consistently uneven (as OS already mentioned)
4. The angle of the bevel is so steep that the quality of the shave suffers. This usually happens when the spine is taped and you try to take a 1/4" chip out of a 4/8 blade.

I've honed wedges where the spine wear and bevel meet in a number of spots. They still shave well. On such blades it becomes important to hone evenly and think of it more as polishing (as in nihon to) than honing.

Thanks guys. So it sounds like I'm not actually in that bad a spot here. The hone wear is extensive but not A)sharp, B) anywhere NEAR the bevel or C) uneven. (Even if it were, I would NEVER bin it...Something could be done, I'm sure!)

I'll give it a few rounds on the hone--it shouldn't need a lot, it pops hairs like crazy and under magnification looks smooth as glass.

Most likely it is an indication of a razor that was a smooth shaver, and thus much used. Apart from cosmetics, even hone wear is not really an issue, especially on wedgey blades such as yours.

Most all of the wedge type razors I have show a heavier hone strip at the spine and a wider bevel than my hollow ground blades do. Hone wear will show heavier on the wedge types faster than the hollows due to the geometry of the blade grind. This is typical and does not signal a lot of honing. A lot of us tape the spine on wedge type razors to reduce the metal removal and speed up the honing process. It also keeps the hone wear at the spine to a minimal. I believe there was a post a while ago on this topic investigating weather there was a method of honing the wedges types that differed from our current method. Some of us have purchased a vintage wedge with minimal hone wear at the spine. When we hone it up the hone wear becomes significant almost instantly, which is what inspired the thread. I don't believe this question was resolved. Sorry, I don't have the time to search for the thread right now. I believe Glen had numerous posts to the thread and maybe created it. Maybe he will read this post and locate the thread for you.

Keep the blade and enjoy your shaves with it!

Gents, I am very reassured. Especially since this is the only Japanese wedge I've got...It'd be a shame if it didn't shave.

Now, to fix that scale break...

I don't think it is a problem. I have actually been giving this some thought lately. I tape my spines when I hone them to keep them looking new. That works good if you only hone it a few times. If you have one or two razors and they see a stone every month, after a year of touch up hones, you have significantly changed the geometry of the blade.


The spines were designed to wear. So as you hone the blade, the bevel angle stays constant. To much honing with a taped spine will give you the geometry of a hatchet instead of a long and lean super sharp edge. With a hollow ground, you will eventually ware into the hollow grind swell and beyond making the blade a quarter hollow. Once it hits the hollow grind swell, its life is coming to an end.


I have been thinking of keeping the spines taped for the first few honing's then removing the tape and re-cutting the bevel with the spine exposed to bring the geometry back into proportion. I am lucky enough to have more then two dozen blades in my rotation so they only get a touch up two or three times a year so it would be a couple years of use before I honed down the bevel.


Any thoughts from the razor masters on my idea?


But to your point, an evenly worn spine (even is the key) is little more than an indicator of a well used and cared for blade. A lopsided worn spine is a sign that the blade was not cared for very well and the previous owner did not know how to use the tool.
