Back in July 2006, Don McConnell made reference to a treatise by
Nicholson with regard to file manufacture, and the diagrams appeared to
strongly imply (*) that toothing plane blades were made the same way,
since the teeth shapes were very similar.

I have (finally!) got round to photographing the 3 toothed blades in my
possession.

In the era of digital cameras and desktop photo editing, a clear
photograph with a scale item in it also allows accurate measurement to
be taken, by pixel counting, and then conversion via the pixel count for
the scale item.

So here's the picture:

and I can say that the tooth spacing is quite consistent; the top two
are 17 TPI, and the bottom one very slightly coarser at 16 TPI.

Salaman say that toothing blades come in "coarse, medium, and fine" so I
guess there are more blades out there waiting for me.

The top teeth looks different, but only because the bevel is as
purchased (i.e. steep and rounded ;-) whereas the lower two have been
carefully ground and honed at 30 degrees (I think)

And to add, the British makers were around 85-90

Paul Womack shares with us the benefit of his labours in counting the
teeth of toothing planes, a work in progress since 2006.

This brings to mind the reaction of some members of the List, myself
included, to instructions, contained, it is vaguely remembered, in an
ancient (1920s?) woodworking journal regarding the home-construction of
a toothing plane or, at least, something containing a toothing plane's
iron. Some of us were more than a little dismayed as the instructions
opened with something to the effect: "Trot off to your local ironmonger
and buy a toothing plane iron for 1/6." The anticipated joy of
constructing one's own tool was cruelly crushed in the breast at the
outset. We just do not see, these days, toothing plane irons hanging in
a bunch off a nail at our local ironmonger's store. I resigned myself to
the fact that never would I attempt inlay or veneer work unless I
acquired whatever electrically driven mechanical monster had taken the
place of the toothing plane. I have since resigned myself to the fact
that never will I attempt inlay or veneer work, not having all that many
years left in me.

However, however and however, some little while ago I discovered on the
web sites of Pinie Cz of, I deduce, the Czech Republic, and
E.C Emmerich of Germany United advertisements for wooden bodied
  toothing planes and their irons. They're still out there, Son. The
  only other information I recall is that the Czech plane-makers bed
  their toothing irons at 80 degrees whilst the more conservative
  Germans bed theirs at 70.

I checked. The two lower blades were honed at a very near
to flat 25 degree bevel (what *was* I thinking), whilst
the top one is 33 near the edge, and around 25
at the arris with the back.

I mention this in case someone is trying to calculate
the teeth profile from the projection.
