Well I got a SB Delica today, in a trade. This thing is awesome. I hit it on the SM @ 30 degrees, and then a small micro at 40. This thing gets screaming sharp. Tell me more about SB. What's it typically RC at? What kind of steel would this be considered? Is it a high wear reistance, Or is it just a super fine grain steel, or both? In other words, how is it different that say VG-10? \

Also, have the Stretches in SB been released yet? I am definitely going to pick up a couple, seeing how I like this thing, if they haven't.

Glad you're liking the super blue! I thought it was sharp when I sent it to you but man....that sounds stupid sharp now! I'm interested in picking up a stretch in SB when it's available.
 
What i found with my sb caly3 vs delica in vg10.. while vg10 give fine edge better wear retention, the sb takes fine toothy plain edge and keeps it loong time. At least for my uses. Sb easier to sharpen too.

LOL, it wasn't bad by any means. I am just a weirdo about sharpening knives that I get. I really like it a lot.
 
It's a finer grain steel, try leaving it at 30* instead of a 40* micro depending on your uses for it. SB is used in Japanese cutlery for thin stock and low DPS.
 
Finer grain has nothing to do with what angle you can sharpen at, hardness however does and while they seem to have a decent hardness I have found my endura SB to not hold up that well at thinner bevel angles. 30 inclusive is pushing it unless a microbevel is added.
 
I dig Super Blue....as high carbon steels are my fave compared to stainless. I just wish my SB Endura was not a laminate.

Jason, please look at my other thread here in the Spydie forum on ZDP. I am sure you can explain that one to me better. Thanks a lot!

I see, so what tasks is your endura having issues with at 30 inclusive and what damage is occuring?

I use my knives for whatever needs to be cut which typically includes cardboard, containment plastic, rope, string, carpet, wood, and about anything else you can think of.

Because cardboard is very abrasive it works well to quickly test the stability of the edge. If you have ever sharpened a edge too thin before then you know how the edge acts. It's easily dented or rolled and you will notice these issues instantly. The edge will often look like crushed tin foil or feel extremely toothy within a handful of cuts. Kinda hard to explain if you have never experienced it.

Normally super blue is hardened into the 63-65 range and can be taken to extreme low angles. However, taking the hardness that high in a folder can be risky for the maker so I would imagine the spyderco SB runs closer to 60-62. With that much of a drop in hardness the extreme low angle once possible no longer are.
 
I've taken M4 too thin before and experienced what you're describing, along with ZDP-189 both under 20* inclusive. Just curious on the outcome that you've experienced and what tasks were done that's all. Thanks for the informative reply. :thumbup:

I kinda dig the laminate on my SB Endura, makes it a bit unique beyond just being SB, and the proof line looks cool IMO

Maybe it is me, but I have seen some SB Enduras that show more of the SB then mine does. I would like it more aesthetically if it had a more exposed area. Now, this has nothing to do with performance...as I dig the knife.

Here is mine.

Here's my delica super blue, it's my right hand man at work. Bevel edge 18 degrees, 36 inclusive.

Mine has the larger witness line. It came to me with a small amount of use, and has a little patina. I dig it. When the Stretches come out, I'm in for 3 if I can get em. I can see wanting these to have around for a few years to come.

Anybody have a full super blue and a laminate? Do you like one more than the other?

I've got a solid Super Blue Caly and Mule and a laminated Endura. Solid is the way to go. Hard to explain but the solid SB seems livelier and glides through proteins much nicer than the laminate. Solid develops a nice patina over the entire blade which I prefer.
