Bethatasitmay, the one time I used a Lansky rig, borrowed, to fix the skewed-up edge of an original 9" Cold Steel Magnum Tanto, it did a good job...more uniform than my hands and eyes could have, so claims that it doesn't do the job on blades longer than 4" don't jibe with my experience. Are the diamond stones worth the money? Depends on whether you're edging 416 stainless or RC 61 tool steel. For some knives, it's super-superfluous. slabsides

Afterthought: The tanto has a curved, 'draw-cut' blade. This might have made the difference.
