Black n black. Never cared for a dark black handle in a brown sheath. Black micarta is different, it's kinda grey at times.

I'm having a med brown leather made for m y tan handle,

On the tan color,

I really like the tan handles and when offered on cg knives, the tan finish blades, they dint seem to get as much finish wear that is visible as black finished blades do.
either way they will look awesome.
