Miller bros blades testing m8

[Ironkid883]

Hey to all on bf
I hope this is the right place to put this.
I have been viewing knife videos for quite some time on youtube as do most people.
Recently i saw miller bros blades channel and watched a few vids .
The knives look tough and watching someone drive a knife through a piece of quarter inch steel kinda made me squirm . the knife was the m8 in s30v im pretty sure they also had a z wear model and 35v i think.
That knife seemed pretty tough going throught that steel and having all that weight hanging off it .
The 2 points that bother me about this are:
1.do these type steels really outperform other steels that much ?
2.are other hard use knives as durable .ie busse .treeman .just to name a couple ?
I know the price tag is hefty for a miller bros knife.but if they perform that well and others dont it would seem justified .total noob when it comes to super steels i have no experience with any of them .any info or input appreciated cheers jason

When I bought (most of) my MBBs, they used 5/16" 5160 almost exclusively. I like them for what they are... but what they are isn't usually what I need when I reach for a knife. Generally, my knife needs are better served by smaller, lighter, sharper tools; and I have them in quantity.
A big part of the durability is the thickness and geometry (the same things that make them less than ideal for my day to day needs)... and with any of that type (ie Busse) it's the same compromise.
When/if you need that type of tool, though, you'll be well served. What size M8 caught your eye (9" used to be standard - I have that and 7.5" shown below)

Oh, I'm pretty sure I've seen that placing the blade against something (nail, steel bar, etc) & hammering it in/through causes less damage than chopping into same. Not trying to say the knives aren't tough - there's no denying that they are.
I've batoned that m8 into some nasty twisted up wood...stuff I was afraid to do with my other big knives.

I just saw the test video for the s30v model i think it was standard not sure about length .i was just surprised at how undamaged it was i get they are trade off between thin edge and geometry but if i took either of my three busse kin in sr101.a2 or infi would they be able to perform in the same manner or any of my knives they are all carbon steel im not comparing the makers or manufacturers just wondering do other steel perform as well as they m8 steels
P.s.are the 5160 versions as tough?

Depends on which busse-kin you have...but Busse's warranty practically invites people to do stupid, abusive things with them. They're built to take the abuse; and Busse stands behind their product.

True .i agree with the busse warranty i suppose i just havent seen anyone doin that with theirs neither would i but would still like to see if another steel or manufacturer be able to do the same .i have a load of 5160 truck spring here alot over a quarter inch that i would make something out of to try that test otherwise my bussekin can stick to wood lol i pay enough for them tax n shippin but wouldnt have em otherwise i just assumed they were showcasing these "super steels" and was hoping that someone had maybe replicated that same test with another steel .i have seen the busse car video and some of noss stuff .but nothing like that m8 video

5160 is a spring steel, used for a lot of big knives due to it's toughness. I suppose it's use has fallen off to some extent, due to the popularity of CPM3V; but it's still good stuff.

Also been “replaced” in some applications by 80CrV2 and 8670M.

I haven't tried 80CrV2 in anything big, yet...but I quite like the knives I have in that steel

Also in reference to steel toughness charts the steel s7 seems toughest on paper just low wear whereas the m8 steel seems decent in both aspects i knew i saw that chart online the other day so went pokin for it

 

[jdm61]

The closest that I have seen on paper to S7 is Z Tuff. What makes it interesting is that is supposedly has 95% of the impact toughness of S7 and the wear resistance of A2. Of course, the down side is that it is crazy expensive at the "retail" level. You have to buy like a 300 pound minimum to get the price breaks,

Never heard of them but just checked their site. That M9 looks interesting but I'd prefer a zero grind and not for the prices it appears they are charging. There is a severe lack of proper daggers available (meaning with a zero grind) currently.
