If the knife tips, the mail is over one ounce and requires extra postage. If it does not tip, the letter weighs one ounce or less. The back is marked pat pend'g. The patent was filed Sept 30 1954, and granted Nov 8 1955.
International ONLY through Ebay Global Shipping Program

I pack very responsibly with extra padding to ensure your treasure arrive intact. I ship USPS 99% of the time but reserve the right to use another carrier on larger items to save you money.
I do combine mailing to save you really decent money on the shipping cost. Just put items into your cart and THEN purchase, I will do the rest and if the automatic calculation for price from Ebay is wrong I will cheerfully refund the difference. 
There are some items that are very heavy or I'm already using the maximum size box I can use without a surcharge that I would not be able to combine but most time I can. Any question please feel free to ask!
