A riving knife is a common feature on European saws. Its main

looked into buying parts from Europe to add a riving knife to my
table saw. I finally gave up. One of the barriers to making such a
device standard in the USA is working through the safety and legal
barriers.

It's actually pretty simple and inexpensive. I've got an Old (~8yrs)
Ryobi BT3000 that came with one and All the Ryobi BTXX saws have them.

As do shopsmiths (Models 510 and 520 since the mid 1980s, not the old
no longer made model 500s).

I'm not certain how this applies, regarding the Shopsmith. The Shopsmith
uses a tilting _table_, rather than an arbor, and otherwise has a blade
guard just as clunky as any US-delivered Delta or Powermatic. The tilting
table arrangement makes for some high pucker factor mitered cross cuts, and
effectively precludes its use on anything longer than about 12".
