I can bury my tomahawks at 10-15 on the move. We are talking deep penetration. <----that's what she said
On a serious note, bow skills, hell even spear skills can be useful. I know a few websites that sale quality weaponry. But, it's hard to go wrong with cold steel.
Bow and arrow skills would be very useful in a SHTF scenario. Kinda off topic but a pellet gun would be so useful as well. On topic, unarmed combat would be extremely useful. Nothing will ever play out the way you imagine and being able to back up your debunk weapon with your fists would be very valuable. At the least work out and gain some mass.
