Here's a video I did of my gayle bradley cutting some cardboard. Is this about normal for M4, or should it perform better than this?

can you give us the cliff's notes version? i don't really want to watch almost 5 minutes of cardboard cutting.



:D

Didn't you send it to Spyderco for RC testing?

I never sent it off. I have 2 with the same date code, I figured if they're bad then I'll eventually hear something about knives with this date code being off. Haven't heard anything yet so I figured I'd make a video.

Ah gotcha :thumbup:
 
I kinda had some of the same type of issues/questions with my s30v(spyderco) one of the posters stated that the true strength lies in it's ability to maintain a "working" edge, so I got it hair popping sharp and have not strop it in quite a while ,just being content of just slightly less than hp sharp and I'm real content-dont know if this puts your mind at ease? it did mine.I realize cutting boxes constitutes "work" but you still may be able to cut a while longer to failure!
 
So even after those few cuts it's acceptable that my knife won't shave hair? That just seems odd to me. Especially since cold steels AUS8 faired better.

That was about 50 cuts or so on cardboard and from the video it was still sharp slicing through paper.

Now the High percentage Vanadium Steels develop a working edge that will just keep cutting for a very long time. What they lose is that refined edge that you seem to be focused on here.

If you cut until dull (Won't cut Printer paper clean) with AUS-8 and that GB you would really see how much different those two steels really are. Be prepared to cut a lot of cardboard though and I mean a lot of cardboard.

I agree, since reprofiling my GB i've only had to give it a proper sharpening once. That was after sectioning off a giant rug into small trash sized pieces. Even after that the knife had a good edge still, but I figured it needed a little touch up. As of now, it only gets a stropping once or twice a week for a minute or two. It out shines Aus 8 by such a large margin I can't even begin to explain.

Yeah the V steels like M4, S110V, 10V, 15V, S90V, K294, S125V are so much different than what most are used to. :D
 
That's what I was looking for. If you think it's normal then that saves me from having to send them off.

Also I know that AUS8 iisn't going to outperform M4, I was meaning that in my test aus8 did better - and that's why I made a video about it.


Anyway thanks for the info. I think one day I'll push it and see just how for it goes. For now I'm happy that my knives aren't defective. :D

Nice little video. I must say; you get awfully close to your fingers when slicing that cardboard and paper. Be careful and don't lop off a finger.
 
The problem is not the RC, or the steel being used. It's all the incredibly pretentious hype placed on steels that no steel can really live up to. Subjective opinion tends to get overblown, a lot of the time. Take edge sharpness, for instance. One guy will tell you his knife is razor sharp, but when you handle it, the edge is barely on an "ok" sharpness level. But he hypes it up to his friends and other people who have little to no experience with sharpening or handling extremely sharp knives, and suddenly that knife is the " sharpest knife ever! " Because to them, that is what razor sharp is. It's the same for edge retention. If you used AUS6 your whole life and suddenly gain access to S30V, that steel is going seem God-like.

Steel is just steel, some are better than others. But none truly live up to the hype.

One of the reasons why I mention the word perceived an awful lot, perception can have a big influence on what is.

Well, do not believe what people saying about steels here - you never know what those sayings are based on.
CPM M4 is far from being best steel. To me it seems like it performs OK in your test and you should not expect
much better. But I like to see your AUS8 doing better then this - can you do this? And I do not mind and rather
prefer to see full length.

Thanks, Vassili.
