Was hopeing someone would be able to help me as i have alot of sap on some of my cutters and wondering what i can use to clean them up....

this works a treatsoak them in hot water with a cleaning product called ZEST this removes any sap and dirt. I then rub them over with steel wool, then I sharpen them as normal. I find with regular use the black finish comes off them. A great product to restore the black finish is a liquid gun blue it is also available in a cream I prefer the cream.
