K390 and S110V Discussion Thread

[Philo Beddoe]

I don't often agree with you but I'm with you this time.

Ditto :D

[Blerv]

That must have been a lot of emails all on account of me. :D

I'm not done with the Chuck petition yet. The key is to visit places where they will sign anything just to have a moment of attention. Mainly retirement centers and high school campuses. :p

Edit: Sorry, no more threadjacking from me. Based on my calculations K390 is roughly 3.5 times better than S110v, or 280 numbers. Once I can isolate the advantages of the K over the S and V I'll know for sure though. TBD.

Hello Kurt, this is The Internet. Have you both met?

I thought this was the Spyderco forum.

Cut some cardboard with my Forum Knife today :)


Made roughly 800 cuts
Probably should've worn gloves :p
edit: oh and this was on a stropped factory edge

Nice. :)

But where there any huge chips or cracks out of the edge for all of that hard work.... I am survived the blade even survived as S110V is supposed to be so unstable.



j/k... :D

After reading and re-reading some of the posts here trying to make sense of it all, I've come to the conclusion that I like pictures more than graphs. As for perpetuating this hobby of mine, I very much appreciate the OPINIONS of long time knife users who have been doing this for decades and doing tests that most of us can understand.

...now back to that infamous steel ranking thread to determine what knife steel by buy next.

It seems to have done well inspite of all the psuedo science saying otherwise. :D

[ginsuwarrior]

WOW, I know what steel to choose when the cardboards robots rise from the recycling bins to conquer earth. Nice :)

I cant answer your questions using the K390 mule as the subject but how about K390 HT'd by Peter's to 63rc. It's a simple drop point blade that is .114 at the spine and .014 behind the edge

As some interesting questions which would be nice to see people comment on in Spyderco's A11 and S110V blades :

a) what angle is required to obtain stability in a very high polish (face shaving sharpness with reasonable comfort)

I took my blade to 20deg inclusive and shaved my face for sh!ts and giggles. I had no problems with the edge catching or pulling

b) what angle is required with a medium grit finish to achieve enough stability that it would out perform the mid-carbide steels on cardboard/rope

Dont know about specific angles but at 25deg and a 15micron finish I have yet to roll/chip the edge cutting rope/twine/cardboard/plastic/plaster/sheetrock

c) what is the minimum stone quality required to sharpen them effectively

I'd guess SiC but I use 3M diamond PSA on float glass

d) what is the hardest work you can do before the low toughness becomes a liability

I've dug the edge into seasoned oak and twisted hard. No chips to be found

e) what is the performance ratio if it is sharpened in the same time as a low or mid carbide steel (return on sharpening investment)

If the bevel is already set and using diamond or even my Shapton GlassStones the time difference is maybe 5 minutes.

f) is there a difference between Spyderco and other makers in any of this performance

I haven't used my Mule yet

[Philo Beddoe]

Maybe I missed it but does anyone know the hardness of the N5 S110V blade steel?

[The Mastiff]

Quite possibly the most patronizing regurgitation of pseudoscientific bollocks I've heard in a very long time. Somebody please close this thread.

Cut the guy some slack. He's a sasquatch. We're still trying to break him of the habit of throwing rocks and tying trees together for fun. I think he's doing pretty good trying to type with those huge schauschage fingers of his. :) He used to just try to hump the computer then start howling.

It's a beginning.

Awesome results and I like the sweat droplets on the cardboard near the bottom of your pic. Looks like you enjoyed yourself.

I took my blade to 20deg inclusive and shaved my face for sh!ts and giggles. I had no problems with the edge catching or pulling

It was as comfortable as a normal straight razor?

The reason I ask is that this is one of the larger conflicts between the large community which uses straight razors and people who use them occasionally and often use knives. Tom B. as an example shaved with a Spyderco in S90V, but had to go well over 20 dps in order to make the edge comfortable for shaving - but those guys have extreme standards for comfortable shaving.

As a slightly more objective comparison, does the blade do any of the semi-standard HH tests?

Dont know about specific angles but at 25deg and a 15micron finish I have yet to roll/chip the edge cutting rope/twine/cardboard/plastic/plaster/sheetrock

Is that included or per side?

I'd guess SiC but I use 3M diamond PSA on float glass

Can you do edge into sharpening on that?

I've dug the edge into seasoned oak and twisted hard. No chips to be found

At what angle does it start happening?

[capid1]

Cliff,

The shave was comfortable as a double edge. I have used a straight many times but I would not call myself an aficionado. My edge is also much thinner than a Military so that may play a roll as well. I did not try the HHT on the blade.

It was 25deg inclusive

Yes, I can albeit you can't go heavy handed and have to use a bit of soapy water.

Don't know. I'm not interested in finding out on a $400 knife. I may try on my Mule though.

Yep, if we're gonna start on aphorisms...

Pure logical thinking cannot yield us any knowledge of the empirical world: all knowledge of reality starts from experience and ends in it. (Albert Einstein, 1954)

[shunsui]

Our bodies are given life from the midst of nothingness. Existing where there is nothing is the meaning of the phrase "Form is emptiness." That all things are provided for by nothingness is the meaning of the phrase "Emptiness is form." One should not think that these are two separate things.

Figures often beguile me, particularly when I have the arranging of them myself; in which case the remark attributed to Disraeli would often apply with justice and force: "There are three kinds of lies: lies, damned lies and statistics."
