S30v, s90v and s110v destruction test results.

I was interested in your testing. I KNOW that S110v is a fine steel, but after having one in a Manix 2 LW model, it turned me off. I did NOT test the blade in any way, but the knife just gave me the impression of being incapable of any heavy work...due entirely to its light weight...a purposeful selling point.
It was just an impression, and I know that I didn't give the knife a fair chance, but I just don't "trust" LW folders. I prefer 4-5 oz knives, titanium/G10, and am happy with them in that weight range.

I'm in the same boat, but the manix 2 lw handled it well and the weight reduction makes me prefer it over the g10 manix 2. I much prefer steel liners or TI construction in most knives though.
 
Alright, it took around 12 minutes again to sharpen out the chip in the paramilitary 2, the blade was longer so that contributed some, however the chip was smaller, as you can see diamonds aren't bothered by the type of steel much. Just for fun I ranit through the full arrangement, up to the 1000 grit diamond stones, then switching to the 3 micron diamond stones, then the 5 micron strops, then the 3.5 micron strops. This was the sharpest edge I've ever gotten, yet you'll notice the edge is fairly rough looking, and it tore the TP slightly, this is because my 3u micron stones are not completely broken in yet, although they've been used heavily. They actually leave some deeper coarser scratches then the 1k diamonds do, however they leave a sharper edge than the 1k do. However while stropping after 1k produces a very polished edge, using the 3 micron ones then stropping produce the edge you see here, even sharper but also toothy. Useless to those who don't use DMT stones or the wicked edge, but kind of interesting.

Great test for edc knives! I think knives can probably tolerate more than we give them credit for. But I don't know, we need more tests just to make sure :D

And now I'm seriously thinking about upgrading to diamonds from congress rubies and moldmasters.
 
OP, I salute you for this most awesome and valuable thread! Big respect to you for doing something that many of us many of us couldn't bear to do with someone else's knives, never mind our own! Big respect to you for doing this test.

The results are pretty interesting, especially with how well the S110v has handled it all...Looking forward to any and all future testing to come :)

I remember Sal being curious about how well s90v would do when used hard. So hopefully this is of some use to him.

This confuses me a bit...I always assumed that Sal, if anyone, and people like Sal (people who work at a high level within the world of knife production), would be the ones who know most about S90v and other steels when pushed to and beyond their limits.

Isn't hard use testing a part of the testing and R&D that is supposed to happen before bringing a new steel into production? Wouldn't abusive and destructive testing also be included as part of R&D as well?

I'm not trying to disrespect or throw around any negativity, but reading this genuinely surprised me. I would have expected that Spyderco, more so than any other mainstream knife company, engages (and engaged) in enough pre-production R&D testing that Sal would have some kind of solid knowledge as to how S90V, S110V, or any other exotic steel that's been used in a production blade would behave when put into hard use and abusive situations.




Back to the topic though, thanks again OP! Whenever I up getting a Nirvana if my own, I hope to add the data pile of S90V hard use ;) :cool: [emoji106]
 
I'm sure he has a good idea. beyond catra testing, I wouldn't be surprised if they broke blades several ways in testing. But unscientific beating on knives like I do would be pretty hard to make consistant. You could push cut x gauge wire, or have a blade pushed into a wood block with a certain amount of force. But what happens if you did a lateral cut on heavy wire or hit a knot? Would be pretty time consuming to test all that.

What type of work do you guys consider too much for a lw knife like the Manix 2 to handle? Just curious.
 
sbaker, all things being equal, do you think a knife with a micro bevel can be as good of a slicer as one with just a primary bevel?
 
For the manix? I think you'd break the steel before the knife. It wouldn't be my first choice for carving though. The lw native I wouldn't use it to carve or anything that requires a lot of force. About the microbevel. Depends. I doubt you'd notice much difference from doing a couple passes at a few degrees more obtuse. A bevel you can see will definately effect cutting performance though

Sal is typically pretty quick to admit that he doesn't know everything about these steels and often admits he is still learning. Though I suspect his knowledge is far ahead of most of ours, he always seems interested to hear the feedback of real world users. Some of that might simply be humility but I believe he really does use a lot of the feedback he gets here as data points to increase his understanding of how different steels will perform once in the hands of his customers.
 
I've been enjoying thin coarse edges on the high carbide steels for light use EDC. Sharpmaker diamond 30 deg microbevels. They will not survive your hard use tests, but they slice effortlessly, and seem to last months and months when cutting food, cardboard etc.

How does S90V hold up when going through bones in fish and fowl? My knives in XHP, VG10 and S35V do fine with this.
 
It'll probably be fine surfingringo is the one to ask although I'm not sure if you can call the prehistoric things he catches fish

I have worked with thinly ground s90v (think fillet knife thin) and it works fine pushing through very large rib bones on snapper and other large fish. I have both sawed and pushed through 1/8"+ fish bones without any significant edge damage. That is sharpened at 30 degrees with a 40 degree microbevel. I have some thinly ground m4 blades that seem to be nearly impossible to chip that I use for some of the heavier work but s90v hasn't proven to be problematic even under pretty harsh work loads.
