i've had it under a year and there should be nothing that rusts it -- i use it to cut boxes and open packages......

pics of rust?

surface oxidation or is it pitting? SS usually dosen't rust in air unless exposed to something.

It's because you keep it in your pocket. You sweat. Sweat has salt. Salt + water + steel = rust.

Man, even my daily carry Maxam doesn't rust... And it gets subjected to all kinds of abuse.

Stop buying knock-offs from people on the street.

the outside of the knife is fine -- it's the blade that's rusting!

If it rusts and the leachate is not caused by proximity galvanism, the principal is the culprit. Therefore the SS is inferior quality.

In all fairness, there are many different alloys of SS, no? ..

Perhaps the knife's blade is exceptionally strong, but has low corrosion resistance, or something.

It's not the alloy specification it's the grade. Impurities will cause the product to have subpar corrosion resistance.

This can be a double edged sword. (pun not intended!)

Alloys that are extremely resistant to attack tend not to hold an edge as well. (save for extremely expensive applications that you would never find a knife made of!)

Harder allows tend to have lower resistance to chemical attack and corrosion but again as above, select applications will have superior characteristics and the cost is very high.

Ceramics make for a nice edge IMO.

So... knife collector or metalurgist? ;)

If your knife blade is magnetic, then it's made of the lower grade, 400 series stainless and it will tend to rust more than a better grade of stainless. Better grades of stainless have more metals blended in to help prevent corrosion.
