Disassembly is best but not necessary. But you can't leave the pot on the heat if you don't disassemble.
Slight mod to NJBillK's recipe ...
- Wear nylon/rubber gloves so not to dye your hands
- Wash the G10 scales with dishwashing soap to remove dirt and oil
- Get a small ~2qt saucepan
- Add 1qt of water
- Add 1/4 cup of white vinegar
- Add 1pkg RIT Black dye
- Stir to mix well until dye is completely dissolved
- Bring to a boil, stirring occassionally
- !!! Remove pan from heat!!!
- Open knife half way (90°) to use blade as a handle
- Submerge G10 into dye but keep most of the blade out
- Soak for 5~10 minutes, occassionally slowly swishing knife side-to-side
- Check darkness level of G10, soak longer if necessary
- If it takes much longer, remove knife, reheat to a boil
- When dark enough, remove knife and rinse well
- Thoroughly dry knife, use a hair blower drier if needed
- Add a drop of oil to pivot
