Honing with spine leading

[drjay9051]

Being new to honing I'm looking for all the info i can. in the first video of link this guy does his honing leading with the spine (as you would when stropping). Never saw this before . Any comments? Anybody hone this way? In the third video he explains and defends his technique. Interesting !!

No right or wrong way as long as the resulting edge is one that agrees with you . I use edge trailing sometimes on final finishing laps. There are stated pros and cons, but none have any "scientific" basis IMO.

I read about spine leading strokes in a book that was published in the 1800s - so it's not a 'new' thing.

Spine leading strokes can work. Fuzzy could probably come up with pictures showing how they change the final edge. In my experience, edge leading has worked better in every situation, so I simply don't use spine leading passes with one exception. I do a single spine leading pass sometimes coming off my DMT 8k to unfoil the edge. That's the only stone I've ever had any reason to do so, though.

I believe the thread that link mentions (on B&B) had some decent pictures (500x or so iirc, not SEM though), and they showed little difference if my memory is correct. Mind this was many years ago. May be worthwhile for you to dig it up and give it a read if you're curious about spine-leading honing.

There is a published paper somewhere here (from U of Infiana I think?) that said that spine leading lead to inferior edge quality as all of the materials the the hone was removing from the spine and width of the bevel rolled along and buggered up the final edge that in the case of spine leading. Honing with the edge leading. in their report, resulted in a cleaner edge quality.

But, then again, I've heard that we don't shave with microscope pictures, so do what you like.

In the past I've honed with spine leading strokes when finishing or touching up on coticule. Not sure if it helps or not, but I suppose it's something to play around with if you're so inclined. More often when finishing, I will find myself doing "pigtail" strokes; basically a normal x stroke with a little "swoop" or circle added in the beginning of the stroke. Seems to work well...

Ellipses and circles are half spine leading so it can't be bad.
