Hello to all good knife folks, i don't feel realy comfortable asking
question on subject that was discussed on this forum for more then once,
but i feel that i realy have to. Anyway i decided to buy BM710 as EDC , and thats where the problem begins, i am not sure which blade steel i should buy , especially its gonna be also knife that i am gonna use at reserve service duty, and as my sad army experience shows me that its gonna be exposed plenty to highly corrisive environment such as water,sweat and tears. According to my humble knowledge cm154 is more corrosion resistant then m2,
but after searching on this topic in forums, i got realy strong impression that most people who used this knife believe that m2,even after getting scratched and loosing its tefloan coating remains more resistant to rust than cm154, another thing that confuses me about BT, CRKT m16 that i got ,coated with it, and after i left it wet once for several hours, it got rust stains all over the coating itself. Also i would appreciate opinion on how good AXIS functioning will remain after getting sand, mud and blood all over it,

I'd strongly advise getting the M2 blade. I've used it hard for the last 3 yrs. or so, and find it to be easy to maintain if just lightly touched up regularly, and wipe it down when you do so. It gets and holds a wicked edge. Just don't let it get really dull, it can be a bear to sharpen. It's my preferred steel, and I've used most all the "super" steels. I love the axis lock, but cannot comment on it's function under extremely adverse conditions, as I've never subjected it as such.
 
I'd go for the M2. The coating, even after wearing down, still does the job. Also, I was not even remotely impressed with the performance of the Benchmade 154CM I had. It seemed extremely soft.
 
I have one in in lay-away here in a gun store, a BM 710s McHenry & Williams.

I know that ATS 34 and CM154 are pretty much the same thing. I have another benchmade, dont know the #, and it is ATS 34 and I have been more than delighted with its edge holding capability.

My question is; Has the ATS 34 changed over the past few years?

Buzzbait, you said that you were less than impressed with its edge holding capability because of hardness issues. Did you get a bad apple?

From what I understand ATS 34 has been around long enough that any maker can easily find all of the 'secrets' to how to properly heat treat it, and that BM should have no problem doing so.

Am I missing something?
 
HS all the way.

I have a 710HS that, as was said above, takes and holds a wicked edge.

I have a BM690 with the 154CM and, don't get me wrong, it'll take and hold and edge.

But the HS seems to have and edge over the 154cm...
 
Get the M2 you will not regret it. What you need to understand is that M2 is a tooling steel that has no cromium in it so yes it will rust. Now if used on a regular base and not left in water for months at a time you will have no problem. What you have to understand also is that all steels eventualy can and will rust. They are stainless not rust less.

Also surface rust is nothing it does not cause the blade to weaken and it will not brake cause you can see a bit a brown on the blade.

Get the M2 and don't look back you will not regret it.
 
If I was after a 710, this is the one I would get. The D2 steel would make an outstanding compromise between the toughness of M2 and the stain resistance of 154CM (It may even be better at stain resistance with the coating). D2 also holds an edge exceptionally well in my experience. Plus an aluminum handle for rigidity, G-10 inserts for grip, and all for $135. That is a pretty hard knife to beat.

BM 710-02, second knife from the bottom.
 
I love my 710hs. I have had it for 1 year. I use it everyday and i abuse it. The finish is not all black but it i can keep it super sharp with touchups. With my other vg10 blades, ats 55, ats 34, and cheaper ausX i have to actually have to use the sharpmaker process through 3 sets of stones to keep it super sharp. If i had a choice of blade material i would only buy m2 and s30v steel knives.
 
Thank You all for replay on my question, what bothers me, that most of you used m2 in civilized surroindings, but what if knife stays
for couple hours in wet pocket , and you got nothing dry to wipe it?
again, according to Cliff Stump's review on steel i can see that D2
is good option when it comes to holding sharp edge, but is it better
then m2 to when it comes to resisting rust?
 
to Buzzbait :

I realy loved your review on Spyderco Millitary, did you try also to
do all this horrible things to 710HS ?
 
Ok well D2 from BM does not hold the edge quite as well as M2 but now are you looking to shave with the thing after you have cut rope, vines, bark, trees, meat and others then get M2 if you do not need to shave with it after then D2 will do.

Now you have to understand that BM's BT2 coating is one of the best Teflon coatings out there. The only parts I have of the blade I have seen with light surface discoloration was where the BM logo is lasered into the blade and the cutting portion of the blade. There was not enough discoloration to call it rust or to call it detremental to the integraty of the blade.

As for wiping it down you do not need anything fancy a nice quick stroke on the pants to remove any major water accumulation will be more then enough to prevent it fro falling apart on you. Just kiding.

Get one and see how you like it, also if you want D2 with G-10 scales you can also look into the AFCK that offers multiple cary position.

I'm afraid not. The 710 is a great knife, but I never took to it like I did the Military. My 710 has been used hard, but there are only a small handful of folders that I've used as extensively as the Military; namely the large Classic Sebenza, Camillus EDC, Robeson half-whittler and Old timer Middleman.
 
I have the 710hs and have edc it in rotation for 3 yrs. My climate, tropical heat at 38 - 43 deg C, humudity at 80 - 100 % all year round and clipped to my back pocket. I have had beads of water droplets form on the blade and have had sawdust wet stick to it and have blood all over it by butchering chicken. I also have the 710ats and 710cm154, Which do I prefer ? You guessed it, the M2hss.
 
Thanks Kevtan, You gave answer i been looking for, couldnt ask for more specific information. Climate here is not much better most of the time.
If you mentioned it, do you feel difference betwen ATS-34 and CM-154?
I heard people mentioning that there is less unwanted elements in
CM-154 then in ATS-34.
 
As HT by Benchmade per the 710 the 154cm chips less and the grind was thinner. I have had rust form on the blade beneath the thumbstud of my 941 which is 154cm but have had no problems with the M2hss. The grind on the ats was thicker and I have used it to open a can of food by piercing the tin and using the swedge as wedge to open it. The blade was chipped even with the edge set at 50 deg or 25 per side.
