I have a few knives with tanto style blades. One is very angular, with an obvious "V" shape at the "elbow" of the edge joining the two planes. When I hone that blade, I do each plane separately. On another knife I have it features a "curved" tanto blade, where the "elbow" is rounded off (SOG Vulcan Tanto). It's rounded enough that I can generally hone it with one long stroke each side, end to end. But the one Spyderco "tanto style" knife I own is a Vrango, where the "elbow" is slightly dropped. Despite being a strange shape I actually find it useful. The "dip" can easily handle slicing without tilting the knife. But, I'm a little unsure about how I should go about maintaining the edge. At this point, I've only done some gentle honing to the edge. And I've split it up into 2 steps, one for each plane (as I've done with the first knife mentioned). But I'm unsure of how I should deal with it when I'm ready for a sharpening stone. Should it be one long motion, requiring a "pivot" with the hand through the flow? Or should I focus on each plane of the blade separately?
