I was using a T-handle tool when I tore 2 tendons in my right shoulder, and partially tore the long head of my bicep. It was like a shotgun going off in my ear when the tendons snapped! It's been 14 months since it happened, and in 2 months I finally get my shoulder rebuilt.... all because of using a T-handle tool. I still use them though, they are awesome!
Great for a hobbyist, other that I see an hourly tech or mechanic losing time because I can think of at least 3 other tools better for the job and anyone on commission knows time is money
