I was friends with Czeslaw, his son-in-law and it was very sad to se that he passed as well. He was a wealth of knowledge, and though he only managed to teach me a fraction of his knife sharpening method. I Still use his “Secret”compound on cotton wheels to finish my knives. He was probably one of the most interesting people I have ever met. I still have dozens of his knives, including some custom knives that he made. Like him they are one of a kind.
