Just another chopper,
Made from D3 tool steel, 61rc, around 2 ½” of the blade at the point is 13mm thick, over 9mm behind the point all the way to the handle, handle is 10mm tapering to around 7.8mm with a composite rubber and cork handle.
Thanks for looking
Farid

How does the D3 compare to the Rex 121 or 10V choppers you have made?

Thanks for asking, 10v and REX 121 are very highly alloyed steels, more for industrial applications like tooling, they do not have the same toughness as D3, also 10v and REX 121 (more REX 121) does not give you a hair popping sharpness for a long time, they hold a pretty good edge but in general they are industrial grade steels for high wear resistance, the lower alloyed steels hold a hair popping edge a lot better as there is not a very high amount of carbides in the matrix.


I have tested the D3 tool steel extensively and have found it to be an excellent choice for a cutting competition knife.
 
I have found the D3 choppers from Farid to be superb knives. Infact the light weight D3 chopper I have is now my work knife I like it so much. :):thumbup:

Hi Jamie how are you.

Some info on the ‘D’ series tool steels that I use.

D2- 1.55 carbon, 11.5% cr, 0.2 Vanadium
D3- 2.1-2.3 carbon, 12% cr, sometimes steel smelters add 0.2 vanadium
D6- 2.2% carbon, 12% cr, around 1% (W) Tungsten

For info, D7 is a very good steel, I just cannot get it unless I buy 3 tons, it is a none stainless version of CPM-T-440v (CPM- S60), always wanted to try it.
I hope this helps.

Wow, looks nice and heavy at the tip.

I feel the extra weight on the front helps a lot, two days ago I did a cut on a 2 ½” round branch on a tree, that was very easy, also tested it on a 4” x 2”.
 
Hi Farid

May i ask why do you taper the tip to midsection?
I can see a reduction in spine thickness?

The whole idea was to have a lot of weight at the tip so it cuts better, it works, the section at the tip is not tapered, it is a full 13mm thick then it comes down to 9mm and then the handle is 10mm at the thickest, tapering to 7.8mm.
take care
 
Just awesome!!! If you have the means and time, can I ask how thin you take the edge behind the secondary micro bevel there?

Really nice looking work!
