D2 heat treatment, three processes, you can break to 90 degrees.By

I like to experiment with D2 because of its known poor toughness - hence, easy to discern/delineate improvement (if any). Here is my D2 chopper, I posted a year ago

Didn't Kershaw have a large D2 chopper years back? I'm blanking on the name, but it was a big recurve blade.

Well thank God there! Good thing you're posting on a U.S. site. Not many English speakers around here...

Would you consider making a banana tanto out of super powered Chinese (D)ragon 2?

This is too funny.
 
Btw, the Kershaw I was thinking of earlier is the Outcast.

OP - please share more info on ht & perhaps test/video/etc. Better with more data... than wild guessing and dream up possibility from us.

Here is my D2 61rc blade (my reference as cwf ht 1.0) - destruction bending test. Estimated deflection angle about 70-75 degrees (whereas 90 degrees if the red line is at 45 degrees to the green coordinate) prior to yield (no plasticity, right onto fractures/snapped into 2). Confirmed by 2 broken pieces are dead straight - no hint of plasticity - as I was eluded to my previous post.

Nice chopper profile and grip looks comfortable and secure.

In contrast to Outcast ~60rc hardness, my D2 is at 65rc. A little unconventional but functional chopper ;)

Are you sure color was 'black' on 'the' - ahahaha. I'm guessing - Slicer Util? (which you refused to throw away :D)

Once I cut a banana with 52100. The blade immediately turned black.

Luong,

You know which knife it was. ;)

hahahahaha.I am very surprise that liumang come here to advertise here.Could you transform the Chinese word into English. D2 is a good cheap steel,you heat treatment it broken we old impression. Hope you can do better,build a liumang heat treat factory.

Not sure, but I think this might be a burn against the OP. :confused:

If so, that's a pretty sick burn.

I don think it s funny . Knife maker who does not know English language is trying to communicate here . If this continue , make fun of his google english ..... I wonder who will lose more? He or forum? He do something with D2 steel which look amazing ............... Or jealousy is in question?
I laugh at google ,they earn billions and can not make a good translator , shame :thumbdn:

Your test is wrong. First, the angle is defined as the extension of two fixed points. Then，
1, the distance between the two fixed points.
2, the thickness of the material required
3, if the material and section into V type, then need to calculate coefficient.
4, the hardness of the material.
Distance / thickness = aspect ratio
My length to diameter ratio is about 35-40, thickness is 4.7MM, the length is generally within the appropriate range. If the ratio of length to diameter becomes larger, the angle will increase.

(because I can't upload and see YouTube, my test videos are in)

I'm sorry I can't understand what you're talking about. Look bad.
 
Luong,

It was the small paring. I was actually shocked it turned black so fast :eek:
Some white compounds and balanced strop brought it back no prob. :D

The SU is an undefeated coconut breaker for now. Until I get the CWF chomper.

He tried to remind other poster to be aware of language barrier and the limitation of Google translate.
I think if we keep to simple English and shorter sentence, the translation will be more accurate.

I'm wondering why you call yourself wucai liumang. I googled your name 五彩流氓 literally is Five Color Rogue.

wucai（五彩） not five...Meaning a lot of color，Can not translate this meaning directly...
流氓-rogue，There are two words in Chinese.This is not the meaning of the bad guys.
I can not accurately translate the meaning of this ID, it is more like a mood.
Now I find out how badly it is to learn English at school.
