First let me say I realize that sanding G10 can be risky. I am planning to do this wearing a mask outdoors. Wish I could use my palm sander but am too concerned about dust especially since I have trouble breathing. Would 400 grit work? The blade I am thinking about is a CS Recon 1 Tanto but an aggressive scale design isn’t for me. It tends to leave an imprint in my hand. Thanks in advance for any suggestions.
