Contact W/C at Standing Bear in California. He has flown and gave me some tips during my summer trip there. Remember, you have a stamping stick, not a maul, mallet or hammer! I purchased some tools while at Standing Bear's shop and carried them on. They did set the alarm off, but after a separate check through the bomb machine....I was allowed to pass. I also showed them a business card and I do not know if this worked or not?
If all fails, ship it to the store via one of the carries......Priority Flat Rate box with insurance sounds pretty good with tracking, of course! If all fails and they never get there.....well make yourself another set Mr. Tool Maker!
Good luck and enjoy!
