The drop point I was trying to copy a Gromann Belt Knife and used a metric thickness of 154CM Steel and the filet is made from 440C
The guy who they are made for is a repeat customer and he got a bit of a deal on them as he is also the owner of the two goose calls as well.
The Grohmann nock off would be around $225 and the filet would be $150
prices would include shipping
