The most important items I took from the box were ideas, worth at least twice the cost of shipping. A couple of items I want to specifically call attention to...
The ground HSS bits of various shapes and sizes, whomever put those in there, thank you kindly. I routinely mangle bits and having examples (in some cases, large examples) to hold and examine are quite useful in improving my results. Drawings and videos help, but nothing compares to holding a fine example in your hand. Those are still in the box for the next person's advantage as well.
This is what I took. Some may think it's trivial, but I can't tell you how many times I wish I had something better than a paring knife that won't hold an edge in my toolbox. Getting one never seems to make it onto my shopping list so another thank you to whomever placed it there.
I put in a "special materials" item, you'll know it when/if you see it. It's value is less than may of the other items in the box, but I thought one of our members might turn it into something interesting. If you make something from it, please post it!
One last note, I allowed a couple of co-workers to examine the box and encouraged them to take something if it was useful to them. Entertainingly, it was some small HSS blanks which I had put in there that got taken due to the destination machine being a Sherline (I replaced them with more).
Edit: It's in the mail with an estimated arrival of Thursday. The clerk said it weighed 48lbs.
