My friend Brian Burns is the author of the book Double Bevel Sharpening which I have used extensively and referenced numerous times in previous posts. I think his information and techniques are well considered, practical and deserve a place in the pantheon of sharpening methodology. He has just produced and posted an excellent 28-minute video in which he thoroughly demonstrates his technique using his “stone box” and honing guide.
Double bevels (back bevels) may not be for everyone but they may solve your planing problems, allowing you to plane even the most difficult, tear-out-prone woods. Brian has studied planing for over forty years and continues to improve his technique along with his book and fixtures. He’s a valuable resource for anyone using hand planes as well as electric-powered jointers and planers.
