Innovation is carried out on the basis of the traditional folding knife. As a tool needed in daily life, the knife is also a threat to human life. Therefore, this folding knife is mainly based on the user's consideration of the comfort of using the knife.

The exterior design is neutral and simple, with a total of four color schemes, all of which use colors with lower saturation, which increases the advanced sense of the knife, and at the same time neutralizes the sharp and hard feeling of the knife itself, which is easy for women to accept.

Pull down the side button of the handle to unlock the knife body; the button pushes up the knife cover and the knife body to open together, pull up the side button to lock the knife body, and the button slides down to open the knife cover. In the process of opening and closing the knife, the direct contact between the hand and the knife body is well avoided.

The design of the knife body cap takes into account the idea that when the user closes the knife body, the knife body may cut its own hand during the descending process and the user's misoperation. When the knife body is closed, the finger is placed on the knife handle. The two points of injury caused by mouth increase the user's peace of mind.

The design of the sliding key avoids direct contact between the user and the knife body, increasing the user's peace of mind.
The twist design well controls the relationship between the knife body and the knife cover, and at the same time eliminates the user's fear of accidentally falling the knife during use and the worry of accidentally opening the knife body when not in use, so that the user is more at ease.
Based on children's experience and cognition, the design of torsion also avoids children's use.
