A marker ensemble includes a multi-purpose marking tool and a sharpener. The marking tool has a shell, retention sleeve, compression spring, control tab, reversible disk holder, and cap. The shell has an exit opening, an access opening with a mounting socket, and a medially located lateral control slot through which the control tab extends. The retention sleeve has a collet, compressed by the compression spring and uncompressed by the control tab. The disk holder has a body with a retention ridge and a pair of lugs extending from each end to retain a marking disk. One marking disk has a circular periphery and the other marking disk has a toothed periphery. The cap is mounted upon either end. The sharpener includes a blade with a sharpened edge secured to a body with an upper surface, a peripheral surface with a shoulder, waist, and hip, and a lower surface.

An application container includes a main body cylinder, an application tool, and an engagement portion. The main body cylinder has a first end and a second end opposite the first end. The application tool is insertable into the main body cylinder through the first end of the main body cylinder. The engagement portion is positioned within the main body cylinder, and includes a cylindrical portion to connect with the application tool and a connector that connects the cylindrical portion and the main body cylinder. The cylindrical portion of the engagement portion is spaced apart from the main body cylinder.

A chalk holding device may include an elongate shaft having a first end, a second end, and a bulging center portion that slightly curves away from a longitudinal axis of the elongated shaft. It is noted that the bulging center portion is configured to provide a comfortable holding portion for the user, so it is easier for the user to hold the apparatus. The chalk holding apparatus further includes a tightening ring at each of the first end and second end, which is configured to threadedly engage with the first end and the second end to secure the chalk at each end. It is noted that it is easy for the user to replace the chalk when needed. The user can simply untighten the tightening ring, replace the chalk, and secure the new chalk with the tightening ring again.
