With an overall length of 4 1/8 inch in the closed position the Tusok is very handy and practical for everyday tasks. The ramp on the back of the blade can be used to open the blade by striking an object. That way, emergency opening e.g. in a car accident can be done under stress. This kind of opening is called "kinetic opening". It was invented by Bram Frank who owns the patents for it.
The first 1/3 inch from the tip down is kept semi-sharp (non-cutting) so you can use the tip for cleaning fingernails without cutting yourself. You can pick a thread from your knitwear without cutting it. At the same time this tip geometry makes the tip really strong for simple / easy scraping or prying jobs.
