Depends on the quality of the steel and how sharp you can get it. Human tissue is tough stuff, even for "sharp" blades. This is why there are specialty blades (scalpels) just for surgery. You are going to have to make more of a slash cut instead of a stab with this shape of blade as it is rectangular and not pointy, which will require extra force. You are also going to have to cut pretty deep while looking in a mirror to make sure you hit the right spot.
Technically it can be done with this but both your method of cutting and the tool are heavily stacking the odds against you. Do what you want but I would highly encourage you to choose another method if you want success.
