The more I read Wordpress Codex the more often I wonder if tutorials you can find on the net are actually correct. I've found several tutorials about creating metaboxes where user capabilities (when saving the matabox) are being checked like this:

if ( 'page' === $_POST['post_type'] ) {

    if ( ! current_user_can( 'edit_page', $post_id ) ) {

       return $post_id;

    }

} elseif ( ! current_user_can( 'edit_post', $post_id ) ) {

    return $post_id;

}

When I was browsing through Codex page on WP Capabilities I couldn't find edit_post or edit_page capability. There were edit_posts and edit_pages capabilities mentioned on that page. Why there is edit_post instead of edit_posts used in the bit of code I pasted?

You can find list of capabilities here: Roles and Capabilities

There is no capability called edit_post nor edit_page. But...

There is also something called Meta Capabilities.

The capabilities listed on the Capabilities list are global capabilities. So they're saying that user can edit posts or pages. But it doesn't mean that given user can edit given post (for example editors can edit only own posts). This is where meta capabilities are used.
