Finding a knife

Ed:  Before Dave and & left on their travels they went through my collection of pocket knifes and selected a few for possible use on the trail and placed those in a bag.  Dave asked for the green knife to be shipped in the next resupply box.   However we could not find the bag of knifes!

I took a picture of what I could find and asked Dave to pick one:

 

I even offered my Super Knife: 

 

 

It even has a compass and weights less than a pound!    Dave reply was, "That is what 11 times what we need looks like."

 

Since he turned down the Super Knife, I picked the small black knife with the chain in the middle of the first picture and we shipped it the next day.

 

The following day we found the missing back of knifes.   The one we sent only weighted a few more grams than the one he wanted.
