The October issue of Blade has an article urging us to select good steels for our knife purchases. The author, David Rhea, informs us that part of the magic of S30V is the 30% vanadium content. After a double take, I looked again. Still "30%."

I'm far from an expert on steels, but isn't that a tad high?
 
According to Crucible Steel, their CPM S30V contains the following:

Crucible CPM S30V Alloy Composition
Carbon 1.45%
Chromium 14.00%
Vanadium 4.00%
Molybdenum 2.00%
 
Does anybody know if the crucible data tells us about volume or mass content?

Maybe 30% means volume content and 4 % mass content?
 
Guaranteed a misprint. S30V was named after having approximately 3% vanadium (S90V roughly 9%). The chemistry was probably changed afterwards so that it is now more like 4%. Someone saw S30V thought 3 and typed 30 ....
 
All magazines have misprints. I take Blade magazine for what it is and just enjoy the fact that I can get a monthly publication dedicated to knives.

Elemental compositions are by mass, the carbide contents are by volume. In S30V's case they actually come out to the same number, 4% (mass) vanadium and 4% (volume) vanadium carbide, this is just a coincidence.

Wernt by book store and read article again. The may have looked at 1oV and 15V and assumed the pattern extended to S30V.

Yup. Mostly the pictures. Very little useful information since all the knives are wonderful.
 
but the pictures are nice. I actually plan my knife purchases based on looks as much as steel or anything else!
