There is a lot of hype on steels, it is however to very easily cut through it completely, all you have to do is ask a few questions and apply a little logic.
Blackhearted said:
although the material has some superior qualities, are they superior for the intended use?
Look at the massive range of blades S30V is used for, now ask yourself is it anyway possible that the steel could be optimal for all of those blades at the same time, considering they are so varied in scope and range of use?
will the customer actually notice this 'superiority' in the realm of possible daily use, or does it exist only on paper/extreme fantasy testing.
When ever a maker offers a steel "upgrade", ask them specifically how the performance has changed and how has the design of the blades evolved to best use the new characteristics. Assuming they are using it because it works and not just because it is in vogue they will have done extensive R&D including field trials and be able to spell out the answer in some detail.
...so could the test results...
Any time you see makers talk about the capabilities of their knives, tests done, performance statements, ask them the following questions :
1) What steel in that same knife would have failed?
2) What geometry in that steel would have failed?
These are necessary to judge the meaning of the test. Unless you have done the exact same work yourself it is hard to judge if the performance is actually high. Cold Steel used to promote the tip toughness of their knives by stabbing car doors. When people tried it they found it was trivial even with very slim and pointy tips. That test actually sets a very low standard for tip strength.
2) How much further would you have to go to break/damage it?
I took an AUS-8A Deerhunter and stabbed it into a concrete block five times with no effect on the blade (took pieces out of the block each time). On the six'th impact the tip bent, on the 18'th impact the tip broke. Those additional points are fairly informative. Without the first one a lot of people would assume there is no effect on the blade at all, when in fact after the fifth stab the blade was at a failure point. So many times when things are done and "the knife was not effected", you should ask yourself "yeah and what would happen if you did it again".
3) Do you guarantee that performance?
For obvious reasons.
