Its been like 15years - do we have a winner in VG10 vs 154cm?

Small differences in Rockwell hardness becomes even more nebulous if different Rockwell machines were used to measure the knives. The standards used to calibrate Rockwell machines are only accurate to ±0.5 units. So two different machines, calibrated on two different standards, are only guaranteed to match each other ±1. If you are going by the manufacturers' data, then it's going to be two different machines. So in that case, if one blade is measured at 59 and another at 60, you don't really know that they are different hardnesses.
Note: I used the same Rockwell machine and same calibration standard in all the measurements I made.

Backs up what I used to say before I got all edumicaded here in the forums :
Harden the hell out of my knife please . . . then just leave it some where near by the tempering oven over night and that will be good enough for me. I'd rather have it "too hard" and be careful with it than have one of these squishy things that has been tempered for use by orangutans.

Given the choice of 58-59 or 62-64 I'll take the latter every time.
ZDP-189 (65) for ever ! ! ! !
 
For an EDC, VG10 is hard to beat. Pretty rust resistant and a dream to sharpen.

I wouldn't turn down either.

Obviously that knife has a bad heat treatment overall. Probably from pakistan. I've not tried 1095 at 63hrc but I sure wouldn't use it for any tough tasks regardless. The moral of that video is not that 63hrc will Crack imho.

Here is what I'm talking about.
My "Little Monster".
It is White Paper steel = ~ 1095 (plain high carbon)
It is hardened around 63 to 64
For preventing snapping-off-of-the-blade-in-two strength it is clad in non hardening layers of steel on the sides.
Sure . . . I baby it . . . it pays me back with rewards in cutting prowess and edge retention.
I can't put enough exclamation points after that sentence so I won't even try.

By the way this is a dirt cheep knife, as far as REAL knives go, at ~$40 shipped straight from Japan to my door. I've bought three of these over the years by the way.
No disappointment or problem with any of them :thumbsup:
Sorry for the rat hole guys.

Well that one needs to come with a disclaimer.
I didn't get very far but now find I need to put on the head phones and give it another go due to the others in the room being sure I am a complete moron for listening to this "gentleman".
Other readers; you've been warned.
Being very open minded (having zero people on my ignore list) and with head phones now firmly in place . . . we will try this again . . .

Just a quick point: hitachi paper white is really not like 1095 : ) if it's white 1, then it's about 1.3% carbon
http://www.zknives.com/knives/steels/white_1.shtml
...but more importantly, the cleanness of the steel is the power. The white series have ultra low sulphur (less than 0.004%), and very low phosphorus (less than 0.025%)

1095 spec on sulphur is upto 0.05%, which is like 10 times more! This makes a big difference in many ways (less strength etc), ... think of sulphur as the kryptonite to steel :)

the hitachi 'paper' steels have earned a great reputation mostly because of how clean they are, ie super low S & P

While the charts are visually impressive, they are not based on experiments so they are no more definitive than the other opinions in this thread.

Are you sure about that? Do you think people are just making them up? I think at the very least, the chemist who was creating the steels wrote them up based on the properties of the components that go into the steels. I bet some testing was done too.

For example, it has been shown through semi-scientific testing by that rope-cutting Aussie that Maxamet (high 60s Rc) holds it edge significantly better than VG10, (Rc 59-60) for example.

That would be a good thing to ask the guy who put together those charts over at Blade HQ.

Check it out. He's got an article on that subject

BladeHQ contacted me for help with their article before it was posted. And while my contributions were limited, I would say I am as familiar as anyone with how those ratings are devised.

Thank you for the education !
1095 has a pretty good reputation around here so I was speaking generally as in my knife is "just" plain high carbon compared to VG-10 or 154CM.
I did say "= ~" as in sort of like.
Saying what you did makes me want even more . . . some folders with White Paper Steel.:( :rolleyes: rather than this funny 1095 wannabe stuff.
 
I prefer vg10 over 154cm, that's my scientific opinion based on nothing, nothing at all. All kidding aside I've had several knives in both steels and have had better overall results with vg10.
