Subject: RE: Wee pen knife
According to Captain W. E. Fairbairn, in Get tought! How to win in hand-to-hand fighting as taught to the British Commandos and the U. S. Armed Forces (Paladin Press reprint, 1979; "an exact reproduction of the original" [1942]), page 99, figure 112, the heart lies 3 1/2 inches below the surface and a knife attack to it would result in instantaneous lossof consciousness and death would occur in 3 seconds.

Thus a knife with a 4 inch blade would be sufficient and a shorter blade, thrust very hard, might also work.
