Apologies if this is in wrong place but I could find a restoration forum for De's. I acquired a near mint NDC Superspeed this morning and being a little OCD I'm looking to polish up the knurling on the handle. Could anyone tell me what material the handle is so I can get the correct polish? I have seen a few brands on different threads but being in the UK we don't have them. I have brasso and also a plate you use in the sink with washing crystals or baking soda. Are these safe to use. I think the problem may be the depth and fineness of the knurling.
TIA
Paul.
