Totally. For me the Ricasso of the Endura ist practically as good as a dedicated choil. Not less safe at all and almost as comfortable.
When I choke up on a choil or a Ricasso I always put my thumb to the side ot the blade, rarely on the spine. Plus press back against the front of the handle with my index finger at least as much as against choil or Ricasso. Works perfectly.
So the Endura Ricasso is for one as good as a choil for me, plus has the advantage that my hand is closer to the edge in a regular grip on the handle (so NOT choked up).
But then I also choke up on the actual edge of knives with no problem (and yes, my edges ARE sharp... )
Never hurt myself, as long as you just press against the edge and don't move your finger it works well.
