Hello everyone.

I am looking into getting a new Sebenza and have a few questions regarding the steel. I can't access the search function so was hoping I could find some help here.

I used to have a Sebenza in BG-42 and let it out of my hands(stupid me). How does the new steel compare to the old in edge holding, sharpening and corrosion resistance, also how does in compare to 440V in the same areas?

Any help will be greatly appreciated.

TIA,

Roy
 
Frank,

I appreciate the link, but am soliciting user experience as well.

Thanks,

Roy
 
It is my understanding that the new S30V blades are ever so slightly softer than the older BG42 blades, i believe by a Rockwell point or 2. I have heard the justification to be ease of sharpening, others have said that by making the S30V a little soft, it wont chip as easily, whatever the case, most people seem to feel the 2 steels are both excellent, but i have also heard a few people say they think the BG42 was a better steel, tougher.
 
I have found that the S30V steel knives I own tend to chip easy, very small chips but none the less chips, one chipped while cutting the clear plastic off a DVD. I also have noticed some funny discolorations in S30V that I've owned. I don't plan on buying any more knives with S30V steel on them for awile.
 
i have one knife in s30v and it is a custom kitchen klnife with a paul bos HT to 61 rc. it is a royal pain to sharpen but holds a edge longer than any other knife i have. I also have a custom, 11" blade bowie on order with s30v.

Wow, that is certainly a different report than what I have been hearing everywhere else. Oh well, truth hurts sometimes. ;)

What knives, made by who, heat treated by who?
I have a hard time imagining chipping any steel "cutting the clear plastic off a DVD".
I've been using two S30V knives since Blade, and had no problems with either. You could say the DDR ALB has been abused (I've carried it as a work knife+beat on it intentionally), though the Rinaldi TTKK has not, mostly being used in the kitchen and around the house.
 
I appreciate all the input. These are the kinds of responses I am looking for. Real world use and reaction.

Thanks and keep it coming.
 
I've got several custom folders in S30V. The one knife I tend to carry most is in S30V. I have experienced no problems with any cutting chores so far even though most of them involve cutting pasteboard, tape, string, and plastic ties. The S30V has sliced right through everything. My most common edc is a Smith LS-1. What type of knife have you had NGK that chipped and discolored? Real curious about this.:eek: :)

Yep... we need to know who heat treated your S30V knives, plural.
 
I don't need to know who heat treated NGK's knife. Because it don't matter who did it, it was done wrong. Send that knife back, it aint right. Still wouldn't mind knowing what the knife is.
 
A knife made from ANYTHING can be bad if the heat treat was not properly done.. ANY knife that chips on a CD case was not properly treated no matter what material... There are many variables after that too, edge thickness, geometry etc.. But THAT is just a F'ed up blade...

Why not? The search function has been enabled for basic members again. Have you tried?

there is no comparison!!!!!

Crucible is light years ahead of those other guys!!!!

I suggest you read the article in Blade on S30V with Rob Simonich on the cover, it tells just how tough the stuff really is, keeping up with a Fisk forged camp knife in every single test.
 
Frankly, the difference is minimal in reality...

Knives these days are SHARP, no matter what they are made of (it matters "who" they are made by, though!) A S30V blade may "kind of" last a bit longer (a wild guess really, I can't really "time" this kind of thing...), but for careful knife users, any blade will last... for the more reckless friends of ours, no knife will last anyway! Corrosion resistance? I never left my knives behind to rust so I can't tell... in fact, it really takes a lot to really rust a stainless steel!

I haven't got a s60v / s90v knife yet... so can't really comment on these...

It almost sounds like the temper of the blade was screwed up by the heat of grinding the final edge. That would explain both the chipping and the discoloration.
 
I have been using a small Sebbie with S30V for a couple of months now for my EDC, and have had NO problems at all with it. I use it for all sorts of stuff inlcuding cutting copper wire and it hasn't chipped on me yet.

I seem to remember a post by some guy awhile ago, where he tested both an S30V and a BG42 seb, by stabbing them through a car door, and the one with the S30V got a couple of microscopic chips in it and BG42 didn't. Take that for what its worth, I don't plan on stabbing my seb through steel doors, so I am not too concerned. Also, S30V is a tad easier to sharpen due to its lower RC.
 
Since it has not been mentioned yet. The Benchmade 921 Switchback in S30V has has been a great cutter. (I have not abused it however) It is still shaving sharp and the edge is free from chips at this time. I have no experience with S30V by any other maker. I think BM heat treates s30V to about the same as their 154CM. 58-60 HRC Which I believe is on the soft side for this steel. Maybe somebody with much more knowledge than I can enlighten us.
 
Hello. I wanted to thank everyone for their input, I do appreciate all of it.
I also wanted to mention that I just picked up the Green Beret knife and fully intend to put it through the paces as my confidence in S30V has been increased.
Details to follow.
