Zusammenfassung:	Extendable elements (602) of downhole tools (600) are provided having an extension direction component (Ex) perpendicular to a tool axis (Z), wherein a force is applied to the extendable element when in operation. The extendable elements comprise a first cross-section that includes the extension direction component, a first surface (650) configured to receive a first force component (Fi) of the force, the first force component substantially perpendicular to the first surface and a second surface (652) configured to transfer at least a portion of the first force component of the force to a body of the downhole tool. The second surface and the extension direction component perpendicular to the tool axis draw a first angle (A1) that is between 0° and 90°.
