Yeah at first I had thought the abloy cutting blade had to have the special offset cutting blades to produce a working key .
But if someone that wrote that paper had never seen one actually cut He may change his work Or do another paper.
The disklock cuts are semetrical IE cut same on both sides ..so key will work the same way no matter how keys inserted.
If i had not seen a abloy disklock key being cut and only seen the cutting blade I would assume the same ..the offset style of cutting blade used Matters .
but the carbide bits on the blades still face the same way
The carbide cutter bit angle is different only in design.
So keys only cuts in one direction ..so no forward and counter rotation Cutting takes place or is required ..when cutting the key
Full rotation However in one direction is enough to produce cuts on each side of key ...angle cuts Being the same and semetrical Is my observation .. and don't see any change in cutting direction on the abloy key by useing the offset style cutting blade for disklock
A two sided offset blade spinning in two directions ..is not what I have observed At all on a hand cranked Abloy Disklock machine that turns key only in one direction with overlapping cuts ...
You would think Id have to test this or check it out if I was to write a paper on it.
given a flat slotter blade may also do the same job and is a special blade really needed.
https://imgur.com/a/64f4tbIThe same style blades are being used on machines for classic and high profile and only cut in one direction ...and don't
Appear to be different in heights either to make a split or stepped looking cut .
So the flat slotter blade it is ...weapon of choice
Reading other people's works can sometimes be helpful or not.
