The NEXT SALE

Just for fun, how about if any forumite who wishes to sell something from his (or her) private CPK stash pre-announces a CPK format sale and then unlocks it at a certain hour. It'd be a lot of fun, but most and very likely against the BFC rules!
 
My pc stays logged on, but my phone automatically logs me off all day. Something changed in the past few days...
THANK YOU! I thought it was my mind or my phone! Yes, my phone dumps me every time. This just started mid week
 
I read on the Tech Support subforum that putting http:// before www.bladeforums.com in your browser ought to resolve that issue. I did this with Firefox which would not allow me to log in and so far, so good :thumbsup:
 
What does D2 give you that 3V or 4V doesn't?
Good question. Was going to ask the same thing.
Only things that come to mind are:
For the user: potentially cheaper; easier to field sharpen.
For the maker: cheaper to source; easier (and cheaper) to grind

With proper HT, D2 can be an excellent steel, but other than the above I can't imagine it's "better" than 3v in any way.
Don't have any experience or know much about 4v.

Curious to hear what the more knowledgeable members (or Nathan) have to say.
 
#903 on the Ask Nathan Question thread has all the info you guys are requesting:thumbsup:

Yep. Tommy was working on it the same time I was.....LINK

I think the PSF27 D2 HDFK will be a good fit for folks who don't need the extremely high toughness of Delta 3V and want more abrasion resistance for longer edge retention in abrasive materials like hide and dirty vegetation etc.
 
So that post says it's not going to be D2 steel, but PSF27, which is a spray-formed melt steel close to D2 and CPM D2.

On Ankerson's tests, PSF27 got 280 cuts, which is better than Dozier D2, which got 220 cuts.

So I'd guess that PSF27 might have a bit more wear resistance than 3V, but not much. And it will have a lot less toughness than 3V.

On the other hand, 4V will exceed PSF27 in both toughness and wear resistance. A Big Chris blade in 4V (with acute edge width), got 740 cuts.
 
Oyster Oyster i haven't found any D2 easier to sharpen than the D3V and it'll hold an edge longer. Generally D2 sharpens best with diamonds. YMMV.

Thanks for the clarification MS!
Thanks also to Tommy and HK for pointing me/us to the other thread!


I only briefly owned a blade in 3v (by another maker). I've never tried D3v so don't know if it's different to sharpen.

Absolutely agree re diamonds for D2. Since I got those I'm not "afraid" of any steel.

Further to add to the requirement for better stones and gear in general for maintaining the proverbial super steels:

I used to read a lot of rave reviews about KnivesPlus strop block loaded with green compound and the other commercially available strop variants with BRKT compounds or similar. Well, nothing worked well for me on these super steels worth a cr*p and I was seriously getting bummed out that it must've been me till I decided to spend a bit more $ and try diamond paste / CBN and now, wow! World of difference in the results and the expediency of those results.
 
CBN works great for me too Casino. I finish w/ the 1 micron cbn emulsion on leather followed by .5 micron cbn to really take it to the next level!! I have found that diamond spray or paste also works well on CPM/vanadium rich steels.

The green and black compounds are great for stuff like 10xx, o-1, Infi, 5160, 80CrV2 etc.

That's odd, my black and green compounds keep both my D2 and D3V CPK's shaving. The BC didn't come shaving sharp. I spent about 5 minutes or so stropping on black compound and then green and the above photo is the result. That's 1/4" thick D3V fellas.
