What would that do for the knife, asking for a friend….
Briefly, clean the knife with spirits-lighter fuel etc, dry it using paper, wear gloves to avoid giving finger-prints, tape up the bolsters and the blades to avoid rust. Then, prepare VERY strong tea, British/Irish style in a small metal container such as saucepan use boiling water and 3 tea bags, tiny pinch of salt, use enough water to cover the knife when laid down in it, don't put the knife in when it's boiling or you can crack the scales! Wait until it's cooled a bit after say 3 mins, introduce the knife in the brew, you can lay the knife on 1 tea-bag and cover it with the others. Leave say overnight or c.6 hours but it's a good idea to turn it over from time to time.
Don't be alarmed if the blades or liners show black-even stainless can but that's why it's a good idea to cover them with tape and leave half open. Wash carefully und warm water using a toothbrush and washing up/dish soap, dry slowly but you can use a compressed air can to drive water out, use some WD40 and oil on joints, clean blades & liners where needed with metal polish. It's worked very well for me on Bone and even Stag but there IS risk and Stag in particular can look bloated but it regains shape.
However, don't KNOW if it would work so well on Camel Bone it's tougher to dye, you may need to leave it in longer.
