Just wondering if it stains easier than say S30V, VG10?
I have a blade in AUS8 and "Seems" to stain more than the above steels, but there is no science here.
What is the offical word on this?
 
I've had no staining problem with my Voyagers, and i carry them regular and sweat all over them. Extended use for cutting acidic materials (meat, fruits) might cause some light staining but won't affect the function of the blade.
 
As long as you dry the knives after use, there should be no problems with your AUS-8. I do this with my beater CRKT's and they keep on giving.
 
They should be similar given the points on the tie-lines, however because AUS-8A is generally heat treated softer it will have lower corrosion resistance than optimal. The blade finish is also likely a factor.

I've found my mirror and satin finish AUS 8 blades to be some of the most stain-resistant I have. I do think that S30V and VG-10 are even slightly more stain resistant, however. Depending on the finish, again, of course.
 
Very good! Thanks.
I don't have a problem with cleaning/oiling a blade. I do like this knife with AUS8 blade , so it's not a lowley steel. It's a keeper.

Its all about maintenance, do you look after your Cars engine etc ?
Not that hard.
 
I've had the CS Master Hunter for many years and never had a problem with staining. Then I got another CS with AUS-8 and it stained easily. That didn't make sense and I concluded that something happened in the polishing. I repolished it with 400 grit paper and -no more staining !!! So no, it doesn't stain unless you screwup the polishing !!!
 
Hi Gull wing,

AUS8 is a very refined steel with a homogenous grain structure. It is made by Aichi foundry in Japan. It is not a "lowley" steel. It has the balanced amount of everything to provide excellent sharpness potential, good edge retention and good corrosion resistance.

In our Q-fog testing, AUS8 would not be as corrosion resistant as 440C or VG-10, but it tested better than S30V or ATS/154.

Heat Treatment is also a critical area with regards to corrosion resistance. 440C has good corrosion resistance, IF it's properly heat treated. If it's not heat treated at all, it rusts quite quickly.

Also, are you sure what you have is AUS8? Where was it made?
