Seems to be a lot of Griptilians out there! So I take it that S30V is the best steel for the blade? Please forgive the NEWB question...
WP-
I just bought a Mini-Grip with the green handle, which was discontinued in 2004, and sent it to BM to upgrade it to 154cm steel instead of the 400C that it came with... they don't have that sized blade in S30V. From what I've gathered, 154cm and S30V seem pretty close in quality, although it seems that the 154cm is harder to get a razor-razor-sharp edge.
I'm not sure if you've checked out bladeforums.com before, but they were really helpful when I was deciding on my EDC knife. I just checked for the difference between the two, and there was a discussion a few days ago, and a member with more than 14,000 (named Clif) posts had this to say:
"These are the same class of steel, high hardness, high wear, large carbide volume, brittle/inflexible, and low corrosion resistance (for a stainless steel) and low grindability.
The main advantage of S30V is that the wear resistance is significantly higher so you will see an advantage in edge retention for slicing abrasive media. However the advantage is not going to be as much as is often implied, certainly not many to one and unless you do controlled cutting, or just a lot of cutting you are likely not to notice it anyway and the exact shape of the knife you buy will be much more dominant.
For other types of cutting the edge retention will be similar between the two because it can also be critical on the hardness or toughness in which cases S30V has no significant advantages over 154CM. So for example it won't carve hardwoods significantly better than 154CM or hold up better cutting wires and such.
S30V has a higher ability to take finer push cutting edges because the carbides are smaller than in 154CM however most people will never note this ability because you need extreme standards of sharpness for it to be obvious, i.e. judge blades which need a slice to cut loose paper as really dull. In most cases it is offset with the much lower grindability of S30V which makes many people complain about sharpening.
In short, I would not get too concerned about choosing between those two steels because they are both of the same class and work well (or poorly) in the same types of knives and I would instead focus on the knife."
Mods: if that was not ok to post, let me know...
Anyways, that's that!
