This weekend I'm supposed to sharpen a kitchen knife for a lady I've known my whole life. She's turning 90 this weekend and has come to me and asked if I would sharpen a paring knife that belonged to her late husband great- great grandmother(the man was a hero to me when I was a small child, like a grandfather). I have no idea what type of shape this knife is in but if I had to guess it's probably pretty well taken care of considering it's age. I'm assuming it's just carbon steel so it shouldn't be too much of a job IF my earlier assumptions are correct. I have a pretty large collection of different types of stone from the time period the knife was made and would prefer to sharpen it one of them. I was planning on using a washita(initially) and then finishing on a coticule because I'd wager she's going to use this knife regularly and thought a coticule or bbw would be good, even if for just 10 finishing laps to shear off the teeth so it doesn't grab her fragile skin. I'm open to all ideas and also considered starting with a coarse charnley and finishing on a 5x1 Tam O'shanter. What do the sashes of this unique corner of the internet reckon?
