Wakizashi with white spots


DoTanuki yokai

That is the result if someone use the wrong oil !

Especially in Germany many people think that the cheap WD40 is good for conservation of steel!

It is not !

In this oil some aggressive elements etch the surface and the result is you have these white , blind looking spots on the surface.

Dear Ken.

 

I was about to say that a sword bent and then straightened = shinae but having checked I discover that it is not so simple. See here, http://www.ksky.ne.jp/~sumie99/flaws.html

I had not realised that the transverse cracks caused by poor work in the steel were also called shinae.

 

However I do not think that either of these cases apply to the sword posted.

 

All the best.

in the red marked area you see white spots in the Hamon ! 

That mean to me that the spots can´t be tobiyaki.

That was the reason why i write that it might be possible that someone use agressive oil and damage the surface.

Sometimes white spots are actually little areas of black nie (tobiyaki?) Or similar

 

Usually in the dark, using a LED flashlight, you can see that theyre actually black spots.

 

Then again it could be anything. Scratches, old removed rust spots, a bubble under the steel, etc...

 

Here is what the "white spots" really look like under certain light. Little clouds of Nie
