my Cold steel aus8 knife holds edge longer than Spyderco endura vg10...

I think the heat treatment on CS aus8 is better,they really nailed it down!It behaves like a carbon steel but is stainless and is very tough too!I have few older CS aus8 knives made in Japan,and they perform really well too.The new ones made in Taiwan hold the edge same or little better than Spydercos vg10,being easier to sharpen.
 
I have two ideas as to why you're seeing this.

1. Cold Steel has the heat treat on AUS8 nailed down. Just like the performance Buck can get out of 420HC.

2. Spyderco purposely runs the Endura and Delica lines soft because by and large they are the Spyderco knives bought by non knife enthusiasts. People who aren't "into knives" tend to use them harder, so a tougher, softer blade would suit the platform better. Just like they made the tip less pointy and more stout with the E4/D4 versus the E3/D3 because people were breaking the tips off.

I do not know why they run it soft, but it should hold edge better than aus8 for the price youre paying for those knives.VG10 is good steel ,and should get optimal HT , especially with company like Spyderco.

I'm yet extensively testing CS AUS 8, but have just recently started on Spyderco VG-10. Learnt that it is not easy to make it sharp to the level I like.

David (OWE), as not to derail the burr thread, and here seems a more appropriate place to discuss, wouldn't Spyderco more recent VG-10 be improved in HT? They are known to be continuously improving and I guess all these praise on their VG-10 might be true? My Endura is SG, so it might be of older batch. Wouldn't that be?

I'm willing to accept the possibility that newer generations of Spyderco's VG-10 might (really, SHOULD) be better. But I don't know if they are; I haven't purchased any new Spydercos (or many other knives, save for mostly inexpensive ones) in recent years, so I'm hoping some of the issues I see in mine have maybe been 'fixed' or at least improved since.

Pure speculation; but, it occurred to me, if there's any logical reason why Spyderco might've deliberately held back the hardness a bit, maybe it's something to do with the big 'hole' in the blade. Some of their blades with the trademark Spyderco Hole have been known to break at/near the hole, as it's bound to be a little more vulnerable to lateral stresses or twisting in that area (under abusive conditions; shouldn't otherwise be an issue with common-sense usage of a knife). Might've been enough motivation to dial back hardness in favor of a little more toughness. Again though, that's just a wild guess, and there may not be anything to it.

David, good point:)! I still love my Spydercos , but will stick to their s30v which is my favorite!Never let me down as done by them.What I am amazed at is performance of Cold Steel(for the price).Theyre easily best value on market,and definitely most durable.Their choice of better steels lately really topped it off.
