Straight Pin Hole

[tonyg]

Would there be any way to make a staight pin hole on a SAK with no back tools, like a Classic, Ambassador, or Recruit.?

I don't see why not 

Just find a path within the scale that doesn't clash with an existing scale tool slot or where the scale mounts to the pins, then heat up a pin and push it through (celidor melts very quickly and easily), you might have to take a narrow file to the exit point and flatten it a bit to make the head of the pin sit a little nicer/be easier to grab.
