Physics simulation of a blade who penetrate meat

Thank you very much for your reply…
In fact i was following more or less your advice and I’m playing with the collision channels in order to permit the blade to enter inside the mesh… The problem is that I’m developing a demo in VR and in somehow i have to consider the fact i move my blade with the motion controller, so, once i penetrate the mesh (the meat) with the blade I have to deal with the fact the blade it self is fix in the meat and from point of view of simulation i see the meat as a material with a super high density and friction… To simulate this I’m using the physic handle… in fact the blade is grabbed from one physic handle which is in my hand, one physic handle which is attached to the part of body where my blade supposed to be fixed… But at this point i don t know if there can be a proper better way to address this goal…
