In case you were wondering Amy, (the only reader of this blog) a vice is used to hold something while it's being welded, cut, shaped, etc. One turns the handle to tighten or loosen the jaws around the object. Now you know.
Can you see how this relates to my life? The word "vice" is a double-entedre. It can also mean:
1 a : moral depravity or corruption : WICKEDNESS b : a moral fault or failing c : a habitual and usually trivial defect or shortcoming : FOIBLE
2 : BLEMISH, DEFECT
3 : a physical imperfection, deformity, or taint
The sinful nature of man. The vice we fight against.
