Cuda EDC 154CM...WOW!!

However, the design of the Sebenza frame lock is inherently stronger than the lock on the EDC. The EDC lock is rather thin and slender and has a much higher potential for buckling and bending than the Sebenza design. How much weaker? I also beg to differ on the all things being equal SS is stronger than Ti. Ti is tougher than many exoctic steels and has only been held back from use for knives because of the expense of the raw material and the higher costs of machining. We could do some calculations but the real test is breaking a few of them to distruction and I'm not about to destroy my EDC or my Sebenza.

I would beg to differ on a few points here. The design of the two is the same: frame lock. A frame lock is a frame lock. There may be manufacturing differences that lead to better execution on the Sebenza (or it could be that it is hand fitted :eek: ).

A thinner/more slender lock is not necessarily more prone to buckling/bending, if the thinness is accompanied by a stronger material. I'm pretty sure that steel is stronger than titanium, if you maintain a constant thickness; but, it will be much heavier. The value of titanium is not in its strength:volume(thickness), but strength:weight. Additionally, titanium does have other advantages, such as corrosion resistance and magnetic properties (or lack). Finally, over the long run, in a given design, it appears that steel tends to have better wear properties than titanium.

What does all my drivel mean? Not a thing. The Sebenza is an awesome knife; wish I had enough money to make a Seb a priority to buy. :(
 
You are right, standard Ti alloy needs to be 2.5x thicker to be as strong as Steel (and is still at this point lighter). Look at the two, is the Sebi lock 2.5x thicker? If not, the Camillus is actually stronger... I don't own a small Sebi, so I can't say.
 
Having owned a Sebenza before, I must say it is a great knife, but it is has become a knife for the ego. A "must have" for the knife elite. The EDC is practical for everyday use and you don't have to "baby" the knife around until you get that first scratch.
 
I think that CR has been producing left handed versions of the Sebenza for quite some time. And if you ask he will even put on dual thumd lugs.
 
The CR Sebenza (Pre production-1998ish)is possibly the the strongist folder made. I've owned them all from Elishewitz to Crawford to Emerson and I've had all locks fail when 1,200lbs of pressure was applyed via a hydro press. The Sebenza was the only one to hold minus the tip (that was an accident!!:( )Call me crazy for doing this but you can only get results by doing your own research!! Anthony, Where did you hear..."stainless steel will make a much stronger lock than titanium". You or they need to do more research. Concidering that there is more than 5 types of Ti and countless types of SS! Even type 1 CPti has a tinsil strength of 25-40,000psi and 6/4 and 6/6 are pushing 200,000psi. I think It's safe to say that Titanium makes a stronger lock than stainless steel.

I don't. Not as a general rule. Not unless you specify size, and the specific type of metal. Period. You quote some fantastic numbers for titanium (not saying they're wrong). Do you have any numbers to quote for steel?
 
Rockspyder you have some good points! For a fair test in anything all things should be equal,thickness,temper... If you take pure titanium (cp1ti) and make a knife lock out of it will not be very strong, much much weaker than a cutlery grade stainless(304,440).Basic grades of ti have a compairable hardness to Platinum. Most cutlery stainless steels fall somewhere in the 85,000-95,000psi tinsile strength area! That is VERY strong!!:eek:. When you get into higher grades of ti that is when it's beauty starts to be apperent. 6AL/4V ti(the most common grade used in cutlery)is 800% stronger than your basic grade(cp1ti)and 6AL/6V/2Sn ti is 130% stronger than 6Al/4V!!!:eek: SS and and higher grades of ti also have excellent yield strength.
So what does this tell you? It says that stainless steel and titanium are both extremely strong and are inseparable from the cutlery world. Also, when you are dealing with the strength ss and ti both offer, you don't have to worry about your lock giving out if it's made properly, because it's beyond human strength to apply the pressures noted above. I would not be afraid to use a knife with a lock made out of either material; they are both excellent for this application. If I had to bet my life on a lock, I would feel better if it was made out of titanium, especially 6V.
 
Concur with all you said, I do believe. Expecially when it comes to the numbers (didn't look them up myself, and have no reason to doubt you). The only DISadvantages of titanium that I can think of (especially the titanium that is used in knives), is cost and longevity. The only reason I mention longevity is I have read in several places of the liners of the Benchmade AFCK (titanium) wearing fairly quickly, resulting in the liner going "all the war over". And I have heard of at least one instance of this happening with a Sebenza. It was a thread over on the Chris Reeve forum, either late last year, or early this year. Of course Chris made good on it, IIRC. Not that the same or similar doesn't happen with SS. It's just that it STILL happens with titanium, even the best, most expensive stuff.
 
This is a Benza! Top one is Nemo's called Honour and the bottom is mine called Gwaith!

Rockspyder, I think I've seen this happen to a few locks befor. I can't see why it happens to some but not the others.:confused: It must be that a few bad ones get by the quality control guys. Or it might be a bad batch of material. I Guess with anything mass production you always get a lemon, especially in the auto market!!! :D Just be carfull and know about what you are buying and then you don't have to go crazy like me and test it to it's limits just to be sure!!!:) :D :p

Makes sense. Nice 'benza'-pics, General.

PLEASE KILL THIS THREAD that I started, as it has gone way off topic (whatever that WAS...:(.).
 
Cheers chaps! For clarity, the top Sebi is Nemo's, he now has it back! Cheers Nemo! It was this knife that convinced me to get my baby!

:cool:
