Saw tooth pattern

Postby simon » Mon Apr 17, 2017 7:46 pm

I have not seen a saw with teeth like this before. Perforated but no rakers. Anyone have information about it please.

Here is a reference from 'Saws that Sing, a guide to using crosscut saws'

Perforated-Lance Tooth Pattern
This tooth pattern is considered a general utility pattern
that can cut all but hard and frozen wood. It consists of groups
of four cutters set alternately separated by an unset raker with
gullets on each side. The “bridges” between the teeth form
the perforations that give the pattern its name. These bridges
strengthen the teeth and reduce chatter when the saw is
used to cut harder wood. The perforated lance tooth pattern
is sometimes called the racer pattern and old-timers called
it the four-tooth pattern. It was popular historically in the
pine country of the American West, and is still popular
there.

I own saws with Great American teeth, plain teeth and perforated lance teeth. The saws with perf. lance have raker teeth as well.

So if it is a plain tooth pattern with perforations but no gullet or raker teeth could it be a specialist saw,one for a very hard wood as there is not much room for any shavings, or could it be a cosmetic saw? It would seem a lot of work to got to though for a cosmetic saw (one to hang up to look oldie worldie) when you could just get an old one.
