• a groove in the interior chamber, wherein the groove is configured to retain the blade in a ready configuration for coupling the blade to the handle;
• and
• a pivot member secured within the interior chamber of the housing, wherein the pivot member is pivotable between an unlocked configuration and a locked configuration,
• wherein the unlocked configuration of the pivot member is configured to allow the blade in the ready configuration to be coupled to the handle,
