Here's one you won't see very often. a #3-6 with a #6 grind.
Other options include SS, NS and black micarta handle.
Former owner told me he bought new in the late 70's and it came with a JRB.
If I could buy a new one like it today, I'd buy three of them - a 5" for me, another 6" for me, and an additional 5" to give to my next good friend who wishes he could find a stout knife that cuts like a light saber
Yes, the #6 grind cuts that well.
