Spyderco tuff overstiff detent. Factory addition that would be a simple fixz

It does loosen up a tad.
It's still got more detent than my other folders, which is fine.

Yeah, I actually like the extra detent on the Tuff. It's perfect.

But, I have stabbed myself in the butt with my Military while putting it in my back pocket and the blade had opened up an inch... So, I have a unique point of view regarding the usefulness of a strong detent.

That is a terrifying thought. I cut a nice hole in my front pocket with an Nitrous Stryker not long ago while putting it in my pocket. Almost became assisted neutering. :eek:

Well I can testify to how well a razor sharp M390 Military will puncture through jeans and buttocks. It was my own fault for not being careful enough, but I sure like the detent on my Tuff because of it. :D
 
A Spyderco production knife is brought to you through the efforts of several main players. The Designer, Spyderco, and the Sub contractor. All of these players have standards. The subcontractor is so precise with his machining that the resultant edge of the hole is fairly sharp, this is by Spyderco specs. It is just that the guy making these knives if that good. The knife is what it is, Tuff. It was designed that way and the philosophy of the knife has followed it through a long development process.

This knife has a heavy blade, I'd rather error on the side of retention than to have the blade open in my pocket. To make a leaf spring stronger you have to make it wider, thicker or shorter. To meet the specifications or strength and match the design it was made shorter.

The reason for the hardened stainless lock interface it several fold. Titanium when in intimate contact with steel molecularly bonds, talk about hard to close knives. The only thing preventing this is lubrication and dirt. The Stainless lock interface is extremely durable and will out wear CPM 3V to ti interface. The Stainless lock interface has overflight protection. If you inspect the assembly of the Tuff at this interface you will see 2 post pins machined from the Titanium that the Stainless lock interface mounts upon. The screws just hold it in place. This is a very well thought out lock, that is extremely strong.

I have carried mine for several weeks now, partly in wheat harvest and partly in seeding my dry land wheat crop, The end of my thumb is now clean from using the knife. I have often use the back of the blade as a scraper and it works great.

Even for me I don't see that I would carry this large piece on a daily basis. But when the zombie Apocalypse comes I want this knife with me...Take Care...Ed

I accidentally bought two of these and sent the first one back
before receiving the second.

The first one was stiff but I could still open it with one hand.

I have to use two hands to open the second one,
can't do it with one.

I figure the first one may have been played with at the dealer (box was torn)
and this second one may be untouched, and will break in a bit after I use it, making it easier to open.

That said, this is one hell of a folding knife.

I've been carrying it everyday since I got it.:)
Still no zombies yet...although the drunks in downtown Windsor almost qualify.;)

I don't know if this will work with the Tuff, but if the detent hole is drilled all the way through, one way to make detent easier would be to open the knife to around halfway, flip the knife to the lock side, and gently hammer right over the detent ball. If done right, the scale should push down on the ball, and force it deeper into the hole, creating easier detent. However, do it too much, and you won't have a detent at all. I like strong detents and would leave it alone, but if it is really bothering you...

Wait...through jeans AND buttocks?

The worst I've experienced was when a Sage 2 ruined a pair of pants, but at least my buttocks got away unscathed.

I'm all for a really strong detent.
 
Honestly guys... Don't modify your Tuff if you think the detent is too strong.

Once the knife is broken in and lubed up the detent is perfect. I can easily open it with my thumb and it Spydie drops no problem as well. Any less strength on the detent and this heavy blade would be flinging open on it's own.

Cheers.:thumbup:

And yes, my Military left a puncture wound about 1/2 inch deep and 1/2 inch wide in my buttocks... It was my own fault for not being careful enough with it when putting it in my back pocket, a few beers at dinner might not have helped me either. It was closed when I had it in my hand but somehow opened an inch when I went to put it in my pocket. Man that blade is great at piercing. :eek:
 
I wish they had stuck with the compression lock or gone to a lockback for this knife. The frame lock is not as strong as either of those and sits in the same class as the Military liner lock. Spyderco's own lock tester broke frame locks and liner locks before it broke an unlined frn clipit with backlock. And the Chinook lock broke the machine. The lockback would also take care of the heavy detent issue, as you wouldn't need one. The sharp hole is a missed detail that should be dealt with pretty easily on another run.
 
I can't break a frame lock and know no one that can break one. I have seen broken blades before the frame lock broke. I believe it is a fine lock type for this knife and doesn't feel as cheap as a lock back or compression lock.

Now all the dimples on this knife is quite the eye sore IMHO.
 
A slipjoint would also be a fine choice as we are so often reminded that one cuts with the edge and not the spine and no lock should ever fail under any circumstance. I just think that if you are going to have a lock, it might as well be the strongest you could use. And if this had continued with the initial concept of being a full frame titanium compression lock, it definitely would not have been cheap. Andrew Demko, Allen Elishewitz, STR, Lynn Thompson, and the SPyderco crew have taken framelocks to failure if you'd like to look up the related threads or videos.

I agree on the dimples, ruined the knife for me more than the change in lock choice. I was still considering it until the last reveal, but the dimples, choil, and lock were too much when put together.
 
I dont disagree that lock backs are strongest. And a full frame titanium compression lock would've kicked ass for sure.
 
Ed or Sal posted in another thread that the compression lock was tried and rejected - I am guessing because the compression lock has an inherently weak detent and with a blade that is this size and weight it's a real safety issue.

The controversy about the detent reminds me of the talk about the Umnumzaan, which a lot of purchasers complained about (and which some "fixed" by bending the lockbar to reduce the spring force of the lockbar).

As far as the hole goes, I tend to agree that a little chamfer would be nice, but Sal has posted several times that crisp edges are a mark of quality and attention to detail rather than sloppy work. Basically, anyone can make rounded edges; it takes precision and attention to detail to deliver crisp edges. You or I may not like it, but it's a choice made by Sal.
 
I don't think you would ever want a titanium compression lock. Titanium and steel wearing against each other isn't the greatest. It gets sticky and the titanium will wear fast. A compression lock would be wearing and sticking from the stop pin and blade tang side... :eek:

I really like how they put a stainless steel insert for the lock face on the Tuff. I wouldn't have bought it if the lock face was Ti on steel.
 
The ATR I've used had an interesting hotspot develop from extended use. It's not a good spot for me to have an integral compression lock digging into the meatiest part of your palm.
 
Well, I guess the lockback would have been the superior choice, just imho. No hotspot, no Ti galling, no detent issues, cheaper to manufacture than a slab of Ti milled to shape, dimpled, lockbar bent to tension, and steel lockface added.

I hope the people who bought Tuffs enjoy them. I think the fuller really adds to the looks. Now to continue waiting for the Chinook redesign while alternating my CPM 3V Large Espada, PM2 and Chinook 3. :D

You have a 3V Large Espada? OMG! That's my dream knife!
