Hand Hewn anyday over a cut n glue. 
My point is that these keychains are nothing new, it's a copied design that has been around for a while.
Your looking at a simple novelty keychain, one that is glued with a nice laser engraved lid and another that is hand hewed out, no biggie as it's not like they were a working Neil Cost box call.
I have carried one of these for a simple conversation piece in the past and take them to be no more than that as I am sure most would agree they are not meant to be anything more. I purchased a 1/2 dz or so of them and gave them away as the novelty conversation item that they are.
Here is another lid example he had as I kept one of each.
