There are other specialised blades which may have the same cutting angles but very different offsets because of their design for cutting particular types of media eg those which are thick and/or dense.
The most common blade angles are 30, 45 and 60 degree. This value, usually given in mm, varies with the manufacturer of the blade used and is sometimes related to blade angle. Offset is the distance between the centre of the blade shaft and the blade tip. Some machines have a fixed offset and you will not be able to alter them, but where the machine does allow for an offset value to be set in the software ensure you use the correct values in order to obtain the best quality of cut. Instead as the diagrams below show, the cutting tip is offset from the centre thus widening the cutting area of the blade and making it stronger. Most blades follow a set design where the cutting tip of the blade is not in the centre of the shaft because centralising the cutting tip would weaken the blade by mGaking the cutting area too thin and so shortening its life by making it more prone to snapping. Settings that affect the cut include the blade offset and overcut, the blade angle, the blade depth/extension, the force or pressure used, the speed, the carrier or backing of the media and the stickiness of the carrier. Some machines will only have a few settings, other machines will have many. Setting up your knife Every cutting machine will vary in the settings needed to obtain the best cutting results.
