Johnniett, Imagine a straight knife you are holding, pushing down hard on the object you are cutting.......If either blades (which ever blade you have locked in the handle) were to come down and out of the handle, (which it won't). That edge will ALWAYS be a blunt edge.
This is the way this knife was designed, it would NEVER have a sharp edge that could cut your fingers. Because blade edges are reversed, if the cutting edge you are using is pointing down, then other edge hidden in handle is reversed, pointing up in the handle, and if it were to come out the bottom, it is reversed, so you would not get cut.
The blade is locked securely in the handle with a 1/4 inch steel pin under spring load, it is extremely strong. There is also a stop in the handle, when pressure is applied to cut with cutting blade, not only is there a pin to lock the blade, there is also a stop, located inside the handle to prevent rotation of the saw blade in a downward position. The blade rotates 180 degrees, down and back, to rotate from saw to cutting blade.
The best way to understand this very simple and unique straight knife design, is to look at one a few minutes. It is amazing to most how easily it works, and how secure the blade is, once it is locked in. I hope this helps you understand how it works.
