Fine Woodworking sharpening tip

In the new issue #164 on the top of page18, they show a drawing of a jig for
sharpening a scraper plane blade. It basically holds a diamond sharpening
stone at an angle of 30 degrees to a surface that the blade is laid flat
upon. Then the blade is moved back and forth along the length of the edge
being sharpened. This keeps the angle being sharpened constant. I have
some problems sharpening my chisels freehand and was considering something
like this to help.

Questions
1) Does it matter that the sharpening direction is along the edge instead
of perpendicular to it?
2) Could this be adapted for sharpening chisels and plane irons?

Thanks
Frank

Perpendicular produces a stronger edge. Honing produces sets of fine
scratches. If the scratches are parallel to the edge, the edge is
weakened. It's not a problem with coarser grits _if_ you polish out
the scratches with a couple of strokes square to the edge.

Spend ten dollars on a jig. The cheapest ones work as well as the most
expensive.

Frank, get one of the cheap jigs that clamp the chisel/blade and have a
wheel: you set the angle and then just roll the affair back and forth.
Makes it very easy to get consistent results.

I bought the Lee Valley jig and combination water stone set-up and never
looked back. I intend to get one finer stone for finishing, but my plane
irons and chisels all gleam like mirrors.
