As knife habits and knife knowledge evolved over the years, many new owners came to view such staining as a defect or an indicator of poor quality cutlery steel. And with the combination of Schrade's own liberal warranty policies, and those of two of it's major retailers, Sears and Walmart, returns were killing their profits. So they were forced to convert many traditionally 1095 blades, fixed and folding, to stainless.
I see. So that's why they went down hill and ended up with Taylor. What a shame.
