Cap is removed quickly with only 2 turns. The cap can then be clicked to write to the pin end. The weight while writing is optimally without cap on the pen end, with attached cap for long essays rather too heavy. The Mine of the pin is provided upon delivery with a small plastic cap that can not be dry the mine even after prolonged storage. The cap is made concave at the end, allowing to put your thumb on it more clout to apply, which is certainly interesting for emergency responders who want to pursue so discs. As Kubotan it is ideal because you simply dump must palpate the clip only with the index finger and can grip already in the correct position it then. That means you can also blind draw off right out of the bag him. The pin ends protrude even with plump hands far enough from the palm of your hand out. The steel tip is an ideal compromise between effect and proportionality. Also vice versa, the pin is good to keep. Just the little finger into the depression of the clip and you've got the palm a nice edge to effectively implement lever, while the nerve strikes can be performed with the top of the fist, without running the risk of injuring the thumb. I have not been able to test the extent to which the pin may slip with sweaty hands and full of punch, but I must say he has a good twist.
