I am a novice knife maker. Here are the first knives I have made from Nicholson files. The two on the left are neck knives; the three on the right are boot knives.
From left to right:
Butterscotch Micarta, African Paduak, Purpleheart;
African Paduak, Bloodwood with brass spacer
Black linen Micarta, Cocobolo;
Black linen Micarta, Bloodwood;
Black Walnut
You can see that I like to mix materials/color of wood (it's becoming a bit of a trademark of sorts).
I apologize for the black appearance of some of the blades but they are so highly polished they just reflect light.
