When I ground out my first knife it was double high carbon steel and when I was dipping to cool it there was rust forming.I remembered seeing pics of japanese makers with blades sitting in what looked like anti-freeze.So I stopped grinding and ran to pep boys to get two gals of RV coolant to mix in my 5 gal bucket.I have not had any rust issues doing carbon ever since.Has anybody else used coolant in a dip bucket??
