Very cool link to the facts about Buckmasters...A walk down memory lane...
I do not have a recollection about the knife failing a corrosion test. I do remember moving away from Sandblast finish and going with a glass bead finish cause we felt the sandblast was imbedding foreign material in the surface and this material was rusting.
Those were 425M blades and that stuff handled salt water pretty good.
I think the seals ordered 2500 pieces and that is what started the development on this knife. That first year we sold 53,000 pieces so the seal order became pretty insignificant as far as units went.
We had only forecasted doing 20,000 pieces that year so we scrambled all year long to produce.
