80CRV2 Prototype Test Blade

I can see this as an edge of the seat kinda thread. Also, anything with Rick's awesome sense of humor is worth it in that aspect alone lol.

cpm3v has 2.75 V in it not .20 big diff and should not be any problem in finishng

Oh yeah, I know 2.75 V is a relatively huge amount... but it seems even a little Vanadium makes a difference. I don't know firsthand about finishing CFV or 80CRV2, just thinking out loud :o
 
Up to .25V is there for fine grain. .75V gives significant carbides . Butch's damascus idea would be a good thing to try with 1084 and 15n20.

It's not L-2 .It's higher carbon than L-2.

800CRV2 is the German/European designation for AISI L2:

"AISI L2 is a Low-Alloy Special-Purpose Tool Steel grade Tool Steel.

It is composed of (in weight percentage) 0.45-1.00% Carbon (C), 0.10-0.90% Manganese (Mn), 0.50% Silicon (Si), 0.70-1.20% Chromium (Cr), 0.25% Molybdenum (Mo), 0.10-0.30% Vanadium (V), 0.25% Copper (Cu), 0.03% Phosphorus (P), 0.03% Sulfur (S), and the base metal Iron (Fe)."

If you click on the manufacturer's link I posted:

Nope !! Many of the "equivalent" steels are actually 'the closest' ones . The closest one may not be as close as you think !! Always check the composition !
L-2 , C .45-.65, Cr .80-1.30 This is from one of my older books.

AISI modern specs : .45-1.00 C, .10-.90 Mn, .50 Si, .70-1.20 Cr, .10-.30 V, .25 Cu, .25 Mo Certainly with that carbon content range make sure you look at the actual chemistry !

So you're saying the manufacturer's datasheet is wrong, and OL2SP (Aldo buys his W2 from Germany IIRC, so it's possibly what he bought) is not DIN 80CrV2 / L2 as specified on their datasheet??

That's what I posted above. :confused: 80CrV2/L2 fits perfectly in that range.

Looking forward to how this comes out -- a "less likely to rust" 5160 analog would be ideal to me as a chopper.
keep me in mind if you want to widen out your "tester pool". :D

Likewise -- I'm intrigued. Shot Aldo an email :)

The high vanadium content would imply it's more wear resistant than L6...
 
I'm trying to explain the importance of knowing and getting exactly what you want . If you order L-2 from makers and suppliers at random you could get anything within the L-2 carbon range , .45-1.0.
If the maker says it's .80 C then it should be .80 C [except if it's from China where they sometimes play games !]
Those chemistries are nominal as each element always has a range but the maker may melt much tighter specs within the range . .80C makes a good knife , .45 C does not !

In this case Ravne's OL2SP will work well and you should be getting those specs regardless of stated "equivalents " .
Does that clarify things ?

Not really :)

As far as I can tell from the various literature, 80CRV2 is the DIN (Deutsches Institut für Normung) equivalent of AISI (American Iron and Steel Institute) L2.

All alloy specs allow for a range of elements. Crucible's L6 has nickel, LaSalle's doesn't. The AISI L6 spec calls for .65 to .75 Carbon, so depending on which manufacturer and which heat, your carbon content will vary.

In any event, should be a Rose -- I want to try some :)

I worked out a final blade design for the 80CRV2 test knife. I apologize if my wording becomes too technical for the layperson to understand.

My first thoughts were toward something choppy and pry'y...

Then my tastes matured into a design that was more slashy and stabby...
IMG_0026-5.jpg


I think this is the way to go... more to come..
 
Rick, nice yokote on the middle one :) Are you going to do the other ones as Shobu Zukuri (like the drawing and top blade)?
 
Ohh, damn that's looking nice Rick! I love it so far.

They all start off with a yokote, Lazlo... when I eventually manage to screw that up, it is an easy transition into something else.... Ha!

Thanks guys
 
Hurry up and finish this one, ya lazy bum! :D

I/We can't wait to see it! Looking REAL good so far.
