My wife has played oboe at a professional level for many years and also makes her own reeds. She currently uses a Landwell knife and sharpens it with one of the Spyderco medium ceramic whet stones. She is right-handed and evidently that makes a difference in how she sharpens the knife. She begins by drawing the knife, (edge-first), back at 15 degrees firmly across the stone 10 times. She then pushes the opposite side, (edge-away), at aprox 5 degrees six times. She then repeats the first step 4-5 times. This works for her. I have tried to make sense of the sharpening technique and I can't. This is what works for her. Everyone of her fellow players sharpens differently. Her method is fairly close to her friend who was a principal oboist of a major symphony. He first pushes the knife away which works for him but not her. She does not finish with a strop although some players use them. I hope this helps. I have great sympathy for oboe players because of the amount of time they have to spend making their reeds. It is part science and part art with a bit of luck thrown in. Good luck.
