When using the Tooth a Matic in conjunction with the PacaTrapper, 1-person can easily accomplish the task. Note Gregs left hand during procedure. By golly, I think we could have tied his left hand behind his back and he still could have easily trimmer his herdsire's teeth.
Here is another short video of Chericia getting her teeth trimmed a few years ago. Note her bite before and after. A couple of seconds and presto! Perfect Bite!
The Tooth-a-Matic
This video shows 5 seconds of Precision trimming of 4 teeth simultaneously
note: noise in background is 2 shearings going on at the same time as the Tooth trimming
