A clamper includes: a first clamping member having a first base portion and a first contact portion that is to be in contact with one surface of the workpiece; a second clamping member having a second contact portion that is to be in contact with the other surface of the workpiece; and a clamping member biasing member configured to bias at least one of the first clamping member and the second clamping member in a direction of bringing the first contact portion and the second contact portion closer to each other. The first contact portion has a plurality of plate spring portions extending from the first base portion, the plurality of plate spring portions configured to elastically deform independently from each other to come into contact with the workpiece.

A hair clip includes a first paddle extending from a first tab. The first paddle has at least a portion with a width that is greater than a width of the first tab. The first paddle has a first curved shape. A second paddle extends from a second tab. The second paddle has at least a portion with a width that is greater than a width of the second tab. The second tab is connected to the first tab. The second paddle has a second curved shape. The second paddle overlapping the first paddle. A biasing element is disposed between the first tab and the second tab. The biasing element applies a biasing force to the first and second paddles so that in a rest position, the first and second paddles are in a closed position, and, in a use position, a first force is applied to the first tab and a second force is applied to the second tab so that the first tab and second tab are moved closer to one another and the first and second paddles are moved further apart from one another than in the rest position.

A claw type or octopus type hair clip includes a first side, a second side, a hinge pin that pivotally couples the first side to the second side, and a lock that prevents the first side and the second side from undesirably pivoting to an open arrangement. The hair clip may include features, such as tabs that may be pressed together, that release the lock to enable the hair clip to be opened and placed over an object, such as an individual's hair. When lock-releasing features are released, the lock engages, enabling the first side and second side of the hair clip to be pivotally closed while preventing the first side and second side from pivotally opening.

The invention is directed to a device used to help a stylist cut hair, such as during training. Specifically, the training device includes a fastener that is used to removably attach the device at a particular location in a client's hair. The device also includes a plurality of arms attached to the fastener at predetermined angles. The angles are beneficial, ensuring the user holds a section of hair at the proper position. The device can be used as a training tool for new stylists, or with experienced stylists to maintain skills. Advantageously, the arms of the device can be attached and removed as desired by the user, allowing the device to be customized for a particular client.
