Being in the medical field I have seen quite a few sharp objects used inside live organisms (aka humans in the OR). There is abunch of different kind of blades depending the type of cut one wants to do. What is common to all of them is that they are used for cutting tissues with the
edge. Any thin blade that is good for cutting won't be good for prying and torquing. I am sure there are other better tools for the job.
If you look into a orthopedic surgeon's instruments it looks like he went to medschool at Lowe's and got his degree at the Home Depot. Those are tools for prying and working on joints.
With good knowledge of the anatomy one can separate the joints just by cutting on the tendons.
In general, if you get in between muscle groups you can dissect with your fingers and cut at the insertion points. That's how I get the tenderloins and backstraps
