Alrighty then...... To solve the loose pommel problem, I called SOG, but the warranty and service guy was out to lunch. I waited all day, but never got a call back.
I found an old post somewhere online, that described how to cut a paper clip, and bend it into a U shape. Take that, and stick it into two of the holes in the spanner nut, and use a pair of long nose pliers to grip the clip and turn until tight. I did this, and problem solved.
I then went online again and found a pair of circle pliers (also called split ring pliers?), made in China, for a little over $5.00. They are the ones with the ends bent down 90 degrees. I bought it just in case I ever need to tighten the pommel again. I'm sure the pliers will work better than the paper clip, but so far so good.
The guy from SOG called the following day and left a message, but since I had solved the problem already, I didn't call him back.
