I have a Ratmandu, bought it a few years ago from an individual, great knife!
I also have an older Busse, Straight Handle Badger Attack (SHBA) also not bought from Busse. I did recently ship it back to the Busse Custom Shop and it was a great experience, fair pricing and great work! They removed the black finish, gave it a satin finish, new scales and solid bolt fasteners. Could not be happier.
