I would like to elaborate a little more on my interpretation of the markings on the blade,
first the cutting symbol,, nowadays we use scissors and we cut on the segmented line, in snipping type cuts, (------)
if you cut with a blade, you wave the blade back and forth, in a sawing motion, if you were to draw the cutting motion on a surface , with movement,(~~~~)
Aswell the the squiggly line is even more evident, as a visual representation of cutting ; -
In this experiment I provided for example, wich you are invited to recreate.
for the cut, i drew from the top down , one time is enough to get results, but if you repeat the cut motion a few times the pattern only becomes move evident.
for the puncture, it is self explanitory aswell.
