The front bolster for the KN9 will be made of 416 stainless steel. As the bar that I have has been surface ground I used want these flat surfaces to contact the tang.
The bolster pieces are ready to polish.
I have a little bench grinder that I use only for buffing. Some green (stainless) and black (general purpose) polishing compounds make 416 stainless shine like a mirror.
Here's a shot of the front of the bolster pieces. When I finish hand sanding the blade, I'll be able to clamp and drill these for pins.
