I picked up one of these recently and thought I'd post some early impressions of the knife.

The knife is named for the revolutionary Ernesto "Che" Guevara. The name, which appears nowhere on the knife itself, is meant to draw attention to the locking system so I'll start by looking at that.
The knife has two locks, a primary and a secondary. The primary is a variation of a lockback design but is towards the front of the handle rather than the center or the rear and operates a bit differently than the conventional lock back. The secondary lock is a tab which slides forward to securely lock the blade in either the open or closed position.
In the pic below you can see both locks.
In this picture (above) the blade is locked in the open position by the primary lock which is seen on the back of the handle. The secondary lock is seen as the sliding tab which is forward in the locked position as further insurance that the blade is locked. When the tab is in the forward position the blade cannot be unlocked until it is retracted.
In this pic (below) the secondary lock is disengaged and the primary lock is raised to allow the blade to be closed.
When the blade is closed the primary lock alone holds it shut. At this point the knife can be opened one of two ways. One; the lock can be raised and the blade opened with a flick of the wrist or with the opposite hand. Two; the thumb stud can be used to overcome the resistance of the primary lock and the blade opened that way. If the secondary lock is engaged though the blade cannot be opened until it is disengaged. It is important to note that when the blade is open the primary lock alone will prevent the blade from accidental closure. When open the secondary lock adds security though.
I notice that when the knife is open the blade moves a bit, side to side, in the handle. Just a small amount. Pressure downward on the primary lock mechanism on the rear of the handle when I hold the knife eliminates the wobble. This wobble is a result of the design of the lock. I do not know if all Ches' are like this.
The rear of the knife is fully enclosed which is needed for the lock but also protects the blade.
On the ergonomics of the knife:
Both locks are small. Releasing the main lock requires some small direct attention for one handed operation. Using the thumb stud is easier. Activating the secondary lock also requires direct attention. The edges of both are a little sharp. They are ambidextrous, which is a plus.
While the knife has no burrs or edges that can cut the radius on the handle edges are so small that the feel is sharp.
The knife feels slick in the hand. This is not a good thing on a knife that you will use for any length of time or at any hard task. Due to the slippery, smooth feel of the knife in the hand the tendency is to grip it harder to hold it stable.
The shape of the handle combined with the slickness of the smooth stainless steel scales of the handle, are not conducive to a good grip. A knife should be wider towards the end of the handle to help keep it in the hand. This handle narrows towards the end. This knife feels as if it would slip out of the hand rather easily if the blade was caught on something or momentarily stuck. Pulling it would cause it not to come unstuck but to slip out of the hand. The tendency is to grip it tighter but the hand tires more then.
Note the better ergonomics of the handles below...
Note the location and orientation of the pocket clip (seen in the first pic above). It cannot be moved. It can be removed.
This is a good looking knife. The design of the blade is good and the steel strong. I believe the lock is also strong. Or at least strong enough. The slickness of the handle and the shape of the grip make it is not so useful for any hard work. It would not be my choice for defensive carry. In a sense this blade is a light to medium duty knife that is a jewelery knife of sorts. Useful on a pic-nic, for slicing an apple, cutting the end off a cigar, a conversation piece, etc. A touch of class knife. There is nothing wrong with that.
Doesn't remind me of Che though.
