I'm having fun cleaning and lubricating my knives; and I am sure that this has already been done and there might be a thread somewhere, but what the heck, I love this knife. My OCD wins this time.
I might have to come back and edit this with more details, but I think those of us with a Navaja in our collection will appreciate it even more after looking at all the engineering and design that went into this awesome piece of art. Thank you Spyderco and Ed Schempp for a great knife.
Note: I don't recommend you take yours apart unless you are a patient man/woman; and have good dexterity to place tiny screws in tiny holes. And do not over torque any of the screws, I broke one of the clip screws, which was surprising to me, but I did.
I don't know about anyone else, but this is, in my mind, another classic, Mr Schempp is one of my favorite knife designers, and this is one blade I don't think I will ever sell, unless I really need to. I'm still banging my head for selling my large Persian.
The "carraca" sound is made by a small piece of bent wire that fits into the gears of a wheel through a hole in the liner; which is secured to the tang of the blade by two pins; here you can see the gears of such very thin wheel:
There is a total of 18 screws, including the ones securing the clip, and three stainless steel pins, in this complicated but functional design.
There are 2 T9x3 mm screws that fit in the pivot, one on each side of the bolsters, which also serve to hold them in place.
Then there are 12 T6x2mm that hold the bolsters and the carbon fiber scales to the liners, and the liners to the back spacer. 3 outside, and three inside the scales.
There is 1 T6x2mm holding the wire carraca spring to the liner.
And lastly 3 T6x4mm that hold the pocket clip to the handle.
After I removed the three screws from the handles on the presentation side, this is what I found:
Notice the very precise machining in the bolster, a pocket with a channel was made to give space to the screw and wire that make the carraca sound:
The three pins in the knife serve, one as the stop pin, and the other two, which are smaller in diameter but longer in length, to locate the carbon fiber scales in place. Of course the stop pin is the biggest in diameter at 3.49mm.
All three are free to move to either side through their corresponding holes in the liners and backspacer, here is my wrench pointing to one on the back:
The bolster on the lock side is also machined for the lock:
Here is a picture of the gear wheel and the pins that are placed in the tang to hold it:
Here are the components:
I also noticed that everything has to line perfectly or it will not go together the right way. By the way, all those holes in the liners have a specific purpose, (even the largest diameter holes which are there for weight reduction) each one has been placed In the correct position to either hold a screw, a pin, or locate something in place, this is an amazing thought process, at least for a folding knife it is.
Fortunately for me, this knife was made in Taichung, otherwise would cost an arm and a leg, or at least a kidney, I think.
Here is a shot of the back spacer:
And the gear wheel with a dark background so you can see better:
The pivot pin:
The carraca wire and its corresponding screw and washer, that required tweezers to reinstall, and by the way, it has to be placed in just the right position to engage the gears on that wheel, or it won't make a sound.
Here is the back spacer held to the liners by 3 screws on each side, I cannot see the division lines when it is assembled correctly:
Here is the liner/backspacer assembly:
And here is finally put together again:
I probably missed something, I got some more pictures but I think the above ones will give you an idea of what an excellent knife this is. I certainly had fun during this exercise, I hope you enjoy looking at the inner workings of the Navaja; oh you don't have one? Sorry, it has been sadly discontinued; I won't be getting rid of mine anytime soon; but you can probably find one in the exchange someday.
Again, to all Spyderco fans and families, Merry Christmas!!
