The standard is the combat grade.
Originally black finish, expanded to include the green, tan, and some other colours.
Slabs are micarta, normally black or tan canvas.
Finishes like a camo, satin, or double-cut (bead blasted) incur a premium to be added to the base cost.
Slab changes (tiger, snakeskin, G10, etc.) also have add on costs.
Hope this helps.
