Is RFC 1393 implemented by real routers in practice?

Are there any tools that generate traceroutes using it?

I think it is worth pointing out, that RFC 791 defines a record route option, which you will find deployed more widely. I think neither is used often, so it may be easy to confuse the two. –  kasperd Aug 15 at 20:07
    
Thanks, I am using record route already and it appears to be well supported on the Internet. One limitation of record route is that it can only store the first 9 hops (more won't fit in the IPv4 header) –  Knio Aug 16 at 1:08

The new ICMP message type as defined in this RFC actually was added to the ICMP standard - Though it's currently listed as historical in RFC 6918:

 2.6. Traceroute (Type 30)
   This message type is specified in [RFC1393] and was meant to provide
   an alternative means to discover the path to a destination system.
   This message type has never been widely deployed.  The status of
   [RFC1393] has been changed to Historic by [RFC6814], and the
   corresponding option this message type relies on (Traceroute, Type
   82) has been formally obsoleted by [RFC6814].

And mentioned in RFC 6814 where it's formally deprecated:

   The Traceroute option is defined in [RFC1393].  The Traceroute option
   is defined as Experimental; it was never widely deployed on the
   public Internet.

I very much doubt there will be any current tools that would have this kind of functionality supported.

Quoting from RFC6814 which obsoletes RFC1393

2.3. Traceroute

The Traceroute option is defined in [RFC1393]. The Traceroute option is defined as Experimental; it was never widely deployed on the public Internet.

So yes there should have been implementations for this (some one even implemented IP over avian carriers) but I've never seen one.
