Prove it.
I realize the blade looks too long for the handle. But that is because OnShape(and many other types of CAD software from what I hear) don't render images with perspective. This makes aligning things on multiple axis much easier. But it also means that objects/elements don't appear smaller as they get farther away. For instance, take a look at this mock-up of a small quadrotor.
from a bird's eye view its clearly a square with generously filleted corners. But in this image
at least to me it appears slightly warped.
Hopefully in this pic you can get a better idea of the blade/handle length. I assure you I measured, they are size accurate.
Now to address the possibility of the blade getting stuck while closing, the locking element that runs down the length of the handle is made of spring steel, as you can see in this picture:
it is noticeably thinner where it is designed to flex, and that flex is what allows you to unlock the blade by pulling on the tabs just behind the tang. The area of the blade that makes contact with the locking mech in the closed position is almost the same distance from the pivot point as the innermost surface of the locking recess(I know that's fucking confusing, can't find a way to better phrase it, sorry). Because of this, the same spring tension that keeps the lock engaged when the blade is open, also keeps the blade shut nicely.
