Note that the doc string should go before the (interactive) call:

```
(defun clear-kill-ring ()
  "Clear the kill ring variable"
  (interactive)
  (setq kill-ring nil))
(global-set-key (kbd "s-/") 'clear-kill-ring)
```

It probably is. Assuming that you have `s-.` bound to
`cliphist-paste-item` as in your original post, hitting `s-.` will
(presumably; I don't know cliphist) populate the kill ring with the
items in the clipboard history. Emtpying the Emacs kill ring doesn't
change the clipboard history, because they're two different things.

To see the contents of the kill ring, you can evaluate the variable
`kill-ring` in the *scratch* buffer (put `kill-ring` on a separate line
and hit C-j). Or use `C-h v kill-ring RET`.

There's also the packge `browse-kill-ring`, which shows the contents of
the kill ring in a separate buffer and allows you to pick any item to
paste.
