5.2.3 Blade geometry
5.2.3.1 Wedge angle
The wedge angle determines the sharpness of the blade. In theory, a very narrow wedge angle means
a very sharp blade that exerts very little drag force on the material. However, a narrow wedge angle
also results in considerable force being exerted on the blade. The narrower the wedge angle, the
more unstable the blade becomes. For this reason, the wedge angle is always a compromise between
sharpness and stability. Zünd blades are specifically designed and sharpened to handle a wide range
of materials. The additional specifications provided for each blade contain a list of the materials for
which it can be used.
5.2.3.2 Cutting angle
The cutting angle has a major effect on the cutting force. With drag knives, a narrow cutting angle
means smaller drag forces. However, this has the disadvantage of creating a larger overcut.

5.2.3.3 Maximum cutting depth
There is a specified maximum cutting depth for each blade, which is determined by the length of the
cutting edge. The cutting depth which can be achieved depends greatly on the type of material. The
cutting depth of some oscillating blades will be reduced when using the spring-loaded glide shoe.
Please remember to factor in the set depth as well as the material thickness.
