Axis vs tri ad

You have it backwards about where the load has to go and where the minimum 200 pounds must be supported. An MBC knife has to hold a certain load one inch from the pivot. The amount of that load is 200 pounds times the length in inches. A 3 inch blade must hold 600 pounds one inch from the pivot.

The other way to look at it is that an MBC blade will hold at least 200 pounds at the tip, no matter what the length is. Every MBC knife holds 200 pounds at the tip, and that 200 gets multiplied by the blade length to show what it has to hold at one inch.
 
I can see where I was kinda confusing and imprecise with what I was posting, too. In some places I put 'per inch' when it should be 'at one inch', and the Spyderco lock ratings are minimums, while I was saying that certain knives were 'rated' at specific measurements.

The Chinook has to hold 750 lbs at one inch, minimum, to make the rating. It could have supported much more, I just don't know how much.
 
Don't worry about it, I was obviously confused before your posts.:D Thanks for clearing things up a bit for me. If I was indeed correct regarding Cold Steel testing the Chinook(I'm going by memory, which I'll admit isn't the best idea), I wonder which test they used. Did they go by weight hung near the tip like they did testing the triad, or did they use Spydercos' method?

Yes, as I posted, it has to hold at least 750 pounds one inch from the pivot, 375 two inches away, etc.

That is only 62.5 ft lbs of torque.:eek:

I hope most knife locks can withstand such puny levels of torque.:D

But gee, that 750 pounds is a big number.;)
 
The tri-ad locks are very strong, but better than that is they may be more durable than they are strong. Secondly, they can have a very high strength vs weigth ratio, in fact, a 4oz recon 1 is stronger in weight hang tests than an 8 oz framelock.

Here's quick story that happened earlier today; my wifes parents came for a short vist :o

Now, I'm all excited about the many Axis designs out there, and ask my father-n-law, "of all the knives in this drawer (12), which one would you like to replace with your old case knife? ;)

Now before he can answer, I'm already starting to steer him to the proper choice (of course), and point him the Benchmade 556 (Rawr)!

ZOMG - are you ready for this - He reach's into the drawer and go's right past the 556, and over to the Cold Steel mini-Lawman; he opens and closes it a few times and says, "this feels very stout", IS THIS A NEW BUCK DESIGN, with those finger grooves and STUFF! No, No I say, "that's the new Cold Steel design, which compares favorably with the new AXIS lock I've been talking about. Look here at this 556, I can zing it open and zing it closed with one hand while pouring myself a cup of coffee and Talking on my Cell Phone!!!

All righty then, here's my opportunity to slip him the 556; and BAM!, he pulls out 'my only' Buck 55 (custom), opens and closes her a few times and says, "now this is a knife"; puts it in his pocket, mutters something about needing a Real Edge and walks out of the room. :foot:

I find it funny so many people fault the AXIS lock because the omega springs can break. A search for "broken omega spring" produces 94 threads on this website. I am in the process of reading through them to see how many people have actually had a problem, but for the most part it is brought up from people saying 'the AXIS lock sucks because the omega springs can break' but they have not actually had it happen. There are probably about 20 people on this forums that have reported a broken omega spring and even if that is a small fraction of the actual number of broken springs that is an insignificant amount compared to the amount of knives that have been made that contain them. Most likely there is a statistically zero chance of having one break and certainly not enough to write off the lock or complain about the fact it can happen.

It has also been shown that a knife can be taken apart and put back together causing the springs to be pinched by the scale and break prematurely. So who knows how many of the springs have broke because a person feels the need to take apart a knife to clean it and then puts it back together incorrectly. I would imagine this is a good explanation for the couple people who have had one break right after the other.

No , this BS , at least with the 710
Virtually every idiot out there can disassemble , and than assemble this knife with ease , and there is not way in hell the springs would be "pinched" by the g10 scale , not even close

If\when the springs break , it's simply because they are lousy POS .

You'd be surprised at how many people have no skills with a screwdriver. I've never had a problem with an omega spring but I've only had a handful of knives with the axis lock.

Doesn't matter
Even if you have shitty hands , you just can't cause the omega spring to pinch the G10 scale , like the poster above claimed
 
I don't know if pinching the spring with the scales is possible, I had assumed that omega spring breakages were due to a bad batch of springs.

Discussing torque on knives is deceptive. I was doing so with Ed Fowler on another thread and some of his fixed blades take about 80 ft-lbs to bend, and there's not even a pivot in them. On a 4.5" handle, assuming the force is applied at roughly the middle of the handle, where you hand is strongest, that 62.5 ft-lbs means you'll need over 300 lbs. to make the lock fail. I dare say if you're pushing on a folder that hard, you're doing it wrong.

I will admit that, after having torqued bolts up to 4000 ft-lbs, 62.5 doesn't sound like much.

Im not sure about the Axis, I have subjected my Grip to decent all aound trauma, but I have batoned cross grain loggs with my American Lawman.

any thoughts? can the axis take the punishment that the tri ad can? :eek:

Lots of thoughts please!!!

This OP question can be decided by him with some pictures. I think they're both pretty darn strong. I think other parts of the knife will fail before either lock fails. :)

I just got my new Lawman and boy does the lockup feel solid...imho the Lawman/Recon 1 are pretty strong knives for the money. The only complaint I have which seems universal is Aus8, I wish they could at least use VG-10 or 154 or offer a "premium steel" versions of the Lawman/Recon 1. You'd think with the amount of folks who have the Lawman/Recon 1 and are unhappy with CS's steel choice some custom maker would offer a replacement blade in a nicer steel in the $130-150 range. Just my $.02.

My pre-2010 Large Voyagers are made in Japan with VG-1 steel. Not sure if it's better or worse than AUS8 but those suckers are ultra-sharp.

I've only been using the clip point for around the house stuff like unboxing Priority Mail, opeing letters, etc. and I've never had to sharpen it yet, just stropping (last night actually) and it's sharp as the day I got it. :)
 
a spring on my cold steel recon one old style broke, knife still works gloriously... a broken spring didn't cause the lock to fail. don't think it is a valid criticism.

The axis lock has redundant "omega springs" so that their failure won't cause the failure of the lock, unless of course they both fail.

I'm sure that if i would of sent in that knife to coldsteel i could of got it warrantied. (i kind of like the weaker spring strength though)
