I soaked my S6 and SS4 in warm salty water for three hours.. Trust me, no contest on corrosion resistance! THERE IS A QUANTUM LEAP IN CORROSION RESISTANCE. The SS4 came out the same way it went in. The S6 needed some t.l.c and a total resharpen to restore it.

I love my S6 dearly. It's had the crap totally kicked out of it, top knife!! My SS4 only has Lansky clamp scars in the black coat.

Is INFI worth the extra? Good question.. Give me a few years with my Badger (when it arrives) and I'll let you know!
