JT,<br><br>I have not carried nails in my PSK yet, although I always keep a variety in my BOB.  As nails they have proven very useful on camping trips.  I also keep at least 2 different blunted nails in many diverse tool & equipment kits.  They make good expedient punches for disassembling tools, equipment, & sometimes guns as needed.  They can always be cushioned if appropriate.  Usually I use a grinder at maximum speed.  That heats them red hot & destroys any temper, thereby making them easier to work.<br><br>John
