If people start crying that Case does not use steels like CPM-20CV, S35VN etc, then I am quitting Bladeforums and start collecting pewter hand painted My Little Pony figures.
If your not collecting s35v and m390 my little pony figures, you're doing it wrong
For the OP, I believe a lot has to do with the fact that case is an established, respected company, and their "surgical stainless", also known as tru-sharp, has been identified by composition, so we know it is at least a respectable steel.
The main problem with the "surgical steel" label, especially from less reputable companies, is that it has been used far to often to cover less then adequate knife steels, most often 420j series, which only has .15% carbon, with upwards to .36 in j1... even Chinese 3cr13 has a minimal threshold of .26%. In knife blade terms, it's like pot metal.
420hc has .46%, which greatly improves edge stability, 440a and 12c27 or 14c28 has over .60%, and for many knife enthusiasts such as myself, those are considered amongst the lowest grade stainlesses that make adequate knife blades due to their edge holding. (Carbon content is the main ingredient in steel that allows it to harden and hold an edge).
So if a company uses the generic "surgical stainless" label, but has no transparency as to the composition of their steels make-up, we assume they are using surgical grade 420j2, which is used in surgical situations, it has great corrosion resistance (makes a great bed pan
), but is very soft and won't hold an edge well.
The only knives 420j really excel at making is salt water dives knives, because of its corrosion resistance properties.
That is why Case gets a bit of a pass on this one.
