Got the Sage 5 today in the mail. Love it. It has a through-the-blade stop pin as well as a "normal" stop pin. I just wondered if anyone would be able to explain how this would work or help? What is the thinking behind this? Not being critical, I'm asking to learn as I don't know what having both would do.

No complaints at all. The Sage 5 I got is freaking amazing. F&F is awesome as usual on Taichung Spydies. For the record, this is one of THE nicest and well built knives I have ever seen. Taichung really hits them out of the park. Great machining. It is a small bit tighter in the pivot than the Para 2's that I have. It seems like it will work itself in nicely though.



I took some pics to show you what I mean about the stop pins. There is a channel in each liner that allows the stop pin that goes through the blade to ride in.

Added more pics. I decided to not take it apart as I don't want to mess up the lanyard pipe. I would probably muck it up.

I may take it apart after I get home from work just to see but I'm not sure. If I do, I'll post pics.
 
Perhaps one is the closed position stop and the other is for the open position? Pure conjecture on my part, as i don't own a sage 5.

More conjecture - but not sure why an internal stop pin would have channels in the liner. Would not stop the blade very well if it could move 4-5mm... Seems like an internal stop pin would need to be fixed into the liners. I eagerly await pics (and my sage 5).

I imagine the stop pin is fixed to the blade and runs through a channel in the liner (as opposed to being fixed to the liner and running through the blade. I have a couple of higher end midtech knives that do something like this.

Yes you are right. Kinda like my chaparral or a Southard. Not sure what I want as thinking.
 
Internal stop pin or not, that thing looks like an excellent EDC. I wish theyd make a lefty compression lock
 
It's hard to tell from the pics as most digital cameras don't seem to show depth very well. Is the blade actually touching the stop pin when the blade is open? Because that big fixed pin isn't just a stop pin. It's a rigid structure that transfers forces to the liners when the liner swings over and wedges itself between blade and pin. Thus closing forces are 'compressing' the liner between blade and the fixed pin. The geometry of the knife may not have allowed an easy conversion to the compression lock and wouldn't hit the fixed pin and the internal blade mounted pin was an easy alternative?

Maybe the internal pin doesn't deform as much since the liner slot is rounded like the pin and provides a bigger area for opening forces to be distributed? A flat spot hitting a rounded pin is going to have a much smaller contact area and higher pressure which will likely allow a flat spot to form much quicker. This will lead to over travel of the lock/liner and potentially vertical blade play. Maybe they are finding the internal pin holds up to flipping better than the fixed pin since many spidies are incessantly flicked open and closed?
 
Riz! I am left handed and find the compression lock (at least on the Para 2) to be very easy and intuitive to operate. Took maybe a little practice at first, but now it's my favorite lock.
 
I have owned 4 different PM2s. I loved the knife a would just use my left thumb to disengage the lock. Dont get me wrong, its not bad at all. I just always wished they would make one lefty so I could try it.

I just checked, by closing my Sage 5 with a narrow strip of cash register receipt paper between the fixed pin and the kick and the paper slid out easily. That makes me think the kick doesn't touch the fixed stop pin, but keep in mind that I only have one to test.
 
I would guess that the redundant stop pin was added due to the thinner blade stock of the Sage versus the Paramilitary 2. The thinner stock results in the force of the swinging blade being concentrated on a smaller portion of the fixed stop pin. By adding a second pin they were able to split that force between the fixed stop pin and the liners. The Sage 5 has the thinnest blade stock of any compression lock Spyderco to date, does it not?

Not by a long shot. Like the other Sages, the Sage 5's blade is 3mm while the Centofante Vesuvius had a 2mm blade and the aluminum and titanium Salsa both had 2.5mm blades. That said, I can't recall anyone from Spyderco ever talking about them, so I'm in the dark as to why some of the newer knives have these internal stop pins, or even if they really are stop pins.
 
Deacon-

Does the blade contact the big diameter fixed pin when the knife is open? Or is it just a part of the lock?

At least enough to create some drag on the paper, but not with anywhere near as much tension as there is between the same paper and the stop pin on my Lil Temp. Seems like the internal stop is being employed to at least some extent in both directions.

One other odd thing, at least to me as I don't own any other compression lock knives with a ball detent. If I let go of the Sage 5's lockbar after barely unlocking the knife and try to close the blade very slowly, the ball detent jams up against the tang and the blade won't close any further.
