When i was a kid , many years ago, i was given the best advise i have ever received about knife maintenance. I had just received my first knife, a Joseph Rodgers, and i was showing it off to an old farmer and he told me how to look after it. Son, he said, a drop of oil every now and then, keep it sharp and use the bloody thing. This has kept me in good stead and has worked for my entire life. Sometimes we just over complicate things, with new products, special oils and such, but sometimes the old ways have stood the test of time and worked back when they had limited resources and still work today. Carry 'em, use 'em, drop of oil and keep 'em sharp.
