I have two antique straights I am in the process of restoring and thus far I have cleaned and oiled the blades but I want to remove the scales on them to clean under them. One of them is a Union cutlery spike which I want to put the original scales back on, the other is a Geo S Saunders Faultless which I plan on making my own scales(thinking out of cedar). What would be the best of removing and replacing them?
