I have a couple of the Little Crow WFTs and they work very well. If doing it over I'd buy a Giraud Tri Way for high volume brass trimming.
The Little Crow WFTs work very well, and so does the Giraud with the Tri-Way cutter.
Might also mention that the Tri-Way also fits in the similar Gracey trimmer. Discovered that after getting a really good deal on a used Gracey a few years ago.
