New aus10 tested on youtube

Blade steel isn't the be all end all. The code 4 is a fine knife but I'd take the Endura over it

Yeah I would too because of the slick scales on the Code 4. I'm not a big fan of VG-10 although I prefer it to AUS8A which isn't bad either.
Can't argue with the value of many CS knives in today's market.
Just look at Spyderco's discontinued list this year and you can see that they try a lot of stuff that doesn't sell well. They make up for it by selling a ton of PM2, Para 3, Delica, etc.
Looking forward to seeing CS discontinued list and maybe some deals. Seems like they usually release in early Nov before parking lot sale.
 
The YouTuber mentioned while seemingly friendly and pleasant has a long way to go on keeping his "tests" consistant and accurate. Aus 10 has been around forever and was mentioned as a great alternative by the late pioneer AG Russell. Heat treat is everything, an overly hardened less chippy steel will amaze in cutting tests but will not work well if put to rough use.
 
I ran some tests on Cold Steels BD1 and found it indistiguishable from S110V from another company. AUS10 by CS would likely be indistinguishable as well.
 
wasnt this thread in the cold steel forum originally?

If you can't distinguish BD1 from S110V then what steels can you tell apart?
No disrespect intended.
 
1095 (annealed), 4116 stainless, and S30V separate themselves pretty clearly.

Yes it was. It was moved to GD when the discussion of other companies came up.

understood. thought my mind was playing tricks on me. thanks for clarifying. appreciated.
 
What I found interesting is how at the beginning it states Aus10 is very close to 440c. But in his cutting tests 440c got approx 70 cuts and Aus10 got 140. Is it the heat treat, or is geometry playing a factor?

Could be either or both. What model knives were the AUS10 and 440C?
 
I have examined them thoroughly. I repeated the tests between S110V and BD1 three times with the same results each time, ie it was not possible to tell the steels in the knives I was using apart based on edge holding tests. I tested 4 steels against each other, annealed 1095, 4116 Stainless, 8Cr13MoV, and S30V. The annealed steel was on a whim, but it did provide an interesting reference. 1095 was easy to differentiate from the others, 4116 separated out from the group pretty clearly, and I ran out of cardboard before being able to tell a difference between the other 2.

Your comments strike me as trolling. I would examine the nature of your tests.

Most likely heat treatment. 440c is usually ht'ed soft and fast because the end product is very cheap. Cold steel seem to have fairly good ht as of recent. I've heard it use to vary in the past depending on the factory used.

Properly ht on 440c for edge retention can go up a fair margin with the use of cryo too. Its no super steel though.

If all are hardened to the same hardness and if all the blades are sharpened to the same angle, and if the blades are tested properly, AUS 10:
♦ holds an edge noticeably better than 440C.
♦ holds an edge in the range of 154CM, ATS34, VG1 and VG10.
♦ It holds an edge noticeably less well than S30V, S35VN, or D2.
♦ It holds an edge substantially less well than M390 et al.

If the AUS 10 is taken to a higher hardness than the others, it will perform differently and will likely outperform 154CM and ATS34. But my personal guess based on a fair amount of my own side by side testing is that you still won't beat S30V with AUS 10 unless the S30V is softer than most companies run it and the AUS 10 is so hard that it's brittle.

That YouTube fella does not perform his testing properly and he does not record the hardness of the blade steel. So what he is measuring, and its significance, is always a mystery to me.
