The solution arrived today. Trissy at Swamprat was very helpful and patient.
I find the handle on this knife to be extremely comfortable. This is my first swamprat. I've got a scrapyard 1311, but don't like the handle nearly as much. It feels a bit too small for me.
Not sure if I'll ever be able to afford a Busse, but I can see myself picking up another rat in the future.
