Answer
For stainless knife handle scratches, sand with the grain using 600, then refine with 800 or 1000.
Why it happens
Stainless handles often have a directional finish, and cross-sanding leaves visible mismatch.
Recommended grit
Use 600 for light scratches, then 800 or 1000 to refine the brushed look.
Wet or dry
Dry first; wet can be used for finer refinement.
Success check
The repaired area follows the original grain and does not show cross-scratches.
What to do
- Identify the original grain direction.
- Test in a small hidden area.
- Sand with the grain using 600.
- Refine with 800 or 1000 if needed.
Avoid: Do not use circular sanding on a brushed stainless handle.
