It's funny that this thread comes up, because it happened to me just recently.
Sharpening is a skill I've developed over time, since about 1990 when I first tried it -- knowing next to nothing about knives OR sharpening. The lesson I've learned is to always be patient and willing to let time run its course: you will learn things over time that cannot be learned lickety-split. It can't be rushed. Sometimes you'll even feel like you've hit setbacks, but even those are part of what you learn. Forgetting something you once knew how to do most often causes you to go back and re-study it. Then, guess what? You'll have it more firmly embedded in your foundation than you did the first time you learned it! It's a
good thing.
I've come across the same lesson with several other things: flying, knot tying, guitar playing... These are things that I once thought I knew something about; then time went by (in many cases, from several years to a decade +!) and then I looked back from the PRESENT and saw how much I had learned between then and now! "Did I really think that was good sharpening??" It was amazing. This is one of the greatest observations I have ever made in my life: "If you give it time, when you get to some point in the future, you will look back and realize how far you've come, and you won't have even realized you were traveling." That understanding is crucial to me now. It is what sustains me and gives me the patience to allow things to happen -- particularly those things whose pace I really am not empowered to alter. Some day I'll be able to play guitar, with practice. Some day I'll be able to tie more complex knots than I already can. Some day I'll be IFR qualified, with practice and study. Some day I'll even sharpen better or more efficiently than I currently do.
But it's a weird coincidence that this thread got started, because just a few days ago I took out my Benchmade 555 Mini-Griptilian and examined what I had thought was a perfectly sharp edge, no burr. And I found a tiny burr along the edge. Let me relate to you: I WAS CRUSHED. Here I was, thinking I knew my **** when it came to sharpening, AND that I not only knew the theory but could put it into practice, and I had a BURR on what I thought was my best sharpening job! So I set about getting rid of it, and every time I lightly stroked the blade on my Spyderco Profile, all I seemed to do was put a burr on the other side of the edge! It took a lonnnng time late that night to get the knife to where I thought the edge was adequately sharpened and the burr adequately removed.
Now I'm going to shop for a strop. I know that the sharpening faq instructs that one should be able to get rid of a burr with just one's stone, and I can -- it's just a pain in the ass and I want to see how well a strop takes care of the problem.
Oh, btw, I still use a technique I pioneered
of using a blue LED to examine the edge in the dark. Holding the spine of the blade near your nose, and the LED light near your eyes, facing away from you, a burr on the blade's edge will be more or less perpendicular to the light, and will reflect it back at you, showing up as a tiny neon line. That's your burr. Turn on the lights, sharpen ever-so-gently, and try the LED again. This also works without pausing to shut off the lights, but the line of the burr will be somewhat harder to discern.
Next thing is I'm going to get a jeweler's loupe. Does anyone here use one to check their edges? What power should I get? I have seen them around with 10x, 20x, and 30x. I'm thinking 20x would be adequate without being too much. Advice?
