What is this, and is it bad?

Hello all,

During my constant perusal of all things straight razor related, I have come across this discoloration on various blades.
Attachment 192056
I was wondering what this process is called. It doesn't look like rust or pitting (but I can't be sure), and I have yet to see patina develop in a pattern like that. When I see this should I not be concerned as it is easily buffed out, or should I run for the hills?

I am just trying to train my eye when it comes to what are acceptable vs fatal flaws. Any input would be greatly appreciated.

looks like oxidation to me... you should be able to get it out like any other form of rust.

Great to know, thanks! :beer1:

I didn't think it looked terrible, but wanted to verify before I fell in love with one covered in that stuff only to learn that it is a fatally destructive process.

Can you feel it with your fingernail? And what do the scales look like?

If you can’t feel it, you are probably ok, but the first thing I look for is Cell Rot with a black patterned stained.

Look at the scales for signs of Cell Rot.

Depending on brand and price, it is not something I would buy.

Wow, thanks for the heads up! Never heard of that phenomenon, and had to look it up (still want to read more about it).

I actually dropped 50 on that blade.:gaah:

It's a Wade and Butcher with what looks like horn scales that are in pretty good shape (for my purposes at least). I hope to use it as a platform for my first attempt at achieving a mirror blade finish. Will officially be the oldest blade that I will have as well. All I know from my research so far is that it must be pre 1891, because there is no mention of "England" on the tang.

Once I get it in my hands I guess I'll know if it was a good purchase or a big mistake. :o

It is often referred to as Devil's Spit. Pretty much that is one form of rust in carbon steel. You can never tell how deep it does, so it may be deep pitting when it is demoed or it may be just on the surface. They only way to tell for are is to start sanding.. The stuff near the edge is the only part that effects the shave, the rest is just aesthetics.

Yup, looks like horn, good.

Can you feel any pitting with a finger nail?

Should be a shaver and the scales will shine up nicely.

Read the library on hand sanding, start with 600 and go up or down from there.

Ok just saw, you dont have it yet.

It appears from the different picture angles that it is smooth, so hopefully it is. I already have the hand sanding page in a tab on my browser ready to go. :tu

Devil's Spit!! :rock:
Sounds bada$$. Hopefully it's not too deep. Thanks for your insight.

I hope to post some killer after shots when I'm finished.

It is called devils spit and unless I get an amazing deal on the piece in question I avoid razors with this condition at all cost. Exceptions are insanely cheap razors so its worth a shot or a razor with awesome scales that I would pay the price I am bidding for the scales alone to use on another razor in case I cant get this one to my satisfaction. It (devils spit) isnt always the kiss of death but more often than not - it is.

Noooooo!!:dropjaw:
I guess I'll be even more happy if I can salvage it then, and will certainly post pictures.

For sure you can salvage it.

It does not have to be shiny to shave… and then there is a good satin finish.

Woldpack34 has posted some super satin finishes recently. That style of razor really looks good in satin, in my opinion. Satin finished blade and gleaming black horn scales look great.

Look up Woldpack’s work. While satin can be used to hide blemishes, satin in the caliber of Mike’s, is actually more work that mirror, because you take it to mirror, and then carefully apply the satin with Croesus Cloth to get a very even finish.

Either way it will be a shaver.

I appreciate your perspective Euclid. That's definitely what it boils down to anyway. What drew me to it initially was the minimal hone wear, so I figured that it would take an even edge relatively easily (here's hoping).

Just checked out Wolfpack's work, and really dig that satin finish. It will be my first Sheffield blade, and at 125+ years old that finish would be fitting to go with the original scales (which are good but not perfect). I can't wait for it to arrive so I can give her some TLC...then put her to work! :whipped:

Yea, she should turn out to be a good shaver but you'll know what you have when you start to clean her up. The "Devils Spit" corrosion can be deceiving in how deep it goes. The concern with corrosion near the edge is that you may have to do a lot of honing, read removing metal, to get past the corrosion for a good solid edge. You'll know there too once you start to hone. I have a few that that I had to hone a lot to get past edge corrosion but in the end got to good metal and a solid edge. Just takes work.

If the horn scales are on the dry side you can give them a good soak in Neats Foot oil to help with that. Goos luck with your project.

Very good point. In fact you should probably start by setting the bevel on this Once you can get a nice clean bevel, you will know it will be absolutely worth any effect you put in. The oil on the scales does do wonders too.

Sounds like a plan. I'll start with a bevel setting and a neatsfoot oil bath and go from there. I am contemplating repairing the two chips in the edge of the scale, but if they don't affect my grip on the blade while shaving I just might keep them for character's sake. :hmmm:

If you want to try and repair the scales here is some food for thought in post #13 http://straightrazorpalace.com/works...-repair-2.html .
