A few more....

hi David...

I have a question for you :)

for combat in cmp 3v
what .. heat's treatment you used?

hrc ?

sorry for my bad english:)
 
Hello pausania, I follow Crucible Steels HT for 3V per their data sheet, issue #5, almost to the letter. (Hi-temp foil wrapped blade into a cold kiln, ramp full to 1525*F, soak for 10 minutes. Ramp full to austinitizing temperature of 1950*F, soak 40 minutes. Aluminum plate quench with supplemental cooling done using vortec cold air gun. Tempering cycle, 1000*F for 2-1/2 hrs x 4 times) End result is a final hardness @ 59-60 HRC. HT using Crucibles mid range recommended austinitizing temp for CPM3V (1950*F) results in a blade that has impact toughness almost twice that of A2 (3V=70 ft.-lb ; A2= 40 ft.-lb)(using Charpy C-Notch impact test). Wear resistance results for 3V are 2-3 times greater than A2 (using crossed cylinder adhesive wear test), (3V=7 ; A2=2-3)(approaching that of M2 @ 8-10) . I've chosen this HT process for 2 reasons, to take advantage of the excellent wear resistance that the vanadium content of 3V provides and also the increased impact toughness that is provided over A2 at the mid-range austinitizing temperature.

The extreme science that goes into high alloyed steels like CPM 3V and the precise, repeatable results that can be attained in heat treat, still, never ceases to amaze me :thumbup: The more I work with and use CPM 3V, the more I like it ! It will take, and maintain, an extremely thin and very aggressive cutting edge. Good stuff !!

And pausania, quit apologizing for your "bad english", I understand you perfectly ;)

David, that hunter is beautiful, I love that wood.

Thank you very much Ralph :) The wood ???

Here's the story, as told to a friend/customer, about the wood scales on the attached pic of a nessmuk I recently made using the same wood as is on the drop point hunter you like.

The wood is a piece of old twisted Birdseye Maple. I sent it out to wssi for stabilizing and also a staining process called chroma-brown. Here's the pretty cool story behind the knife handle(s). When we bought our farm (about 15 yrs ago)(its been here for about 128 years now ) there was a really old anvil in one of the barns. It was sitting on an old log about 2' long. The anvil sat in the barn, on that block of wood for years...... until I started making knives : ) I made a new stand for the anvil (one of which I forge knives on today) and tossed the old log in the corner. It sat there for several more years, until this last winter when I started using it as a splitting block for kindling in my shop. Finally, when I was getting low on firewood this past winter, I decided I was going to burn the block in my shop wood stove. Before splitting her up I knocked some of the bark off. Thank Goodness ! Underneath that bark was the most beautiful Birdseye log I've ever seen : ) Just full of eyes, some spalting and burly twists too ! I promptly cut it into knife handle size blocks and have been sending out small batches to get dyed & stabilized. The chroma-brown process really brings out the beauty. I have some stabilized as "clear" too, which are also really nice, but not quite as nice as the chroma-brown ones, imho : ) I attached a couple of pics showing the log being cut up. What a joyous find it was : ) No telling how many decades the anvil had been sitting on that block. The bottom of the log was in pretty bad shape from sitting on the dirt floor of the barn for so long, but, for the most part the rest was perfect.

It sure is pretty isn't it ?

Hi David,

You don't need to apologize for your photos, they are clear enough to delight the eyes and elicit a 'bravo'. :thumbup:

I LOVE the story about the crusty ol' log turning into beautiful handle material. That needs to be printed on the info sheet for every knife with this material. :)

Thank you very much Coop :)

Very soon I would like to have you take some pics for me. Looking at your work Coop, there's just no substitute. Next to your professional pics I'm just limping along at best ;)

I agree, the story about the birdseye block is really neat :)
 
HI david

Today I received the combat ....:D beautiful

excellent heat treatment
excellent working micarta handle (much better than the bark river) and the blade clean and precise

This knife is very interesting, and its most precious thing is the width of the blade exceptional ... ..
I would have preferred single just the tip of greater thickness ... to ensure greater robustness (but nothing serious ..)
Sharpening also states .. I like very blades with the wire convex
question ground are slightly convex or plans ..?

powerful ..useful in any condition

if you have pictures of combat "in action" I'd like to see them ...:)

a question using the same model for the combat (as blade width, inclination milling, blade length, depth sub hilt)?

thank you ...I hope soon we can challenge your nessmuk knife...:D
