I have taken some measurements from the photos of the Bahco Laplander and the PG-72.
o Both blades are 8 points per inch (the same as 9 teeth per inch).
o They both have straight plain teeth in an alternating crosscut pattern.
o The teeth depth for both blades is around 4.5mm.
I am not sure about the spne thickness of the Laplander but for the PG-72 I previously reported about 1.2mm.
There appears to be a very slight difference in blade profile. The Laplander appears to be more narrow at the end. The following measurements were made from a line representing the teeth points to the spine of the blade at various tooth positions.
(Does anyone know how to do fixed pitch or tables?) I will insert a graphic for my table as I cannot see how to do it otherwise.

In conclusion the blades appear to be very similar with an identical tooth pattern and a very slight difference in profile which may not be significant in any case. I cannot comment on the thickness of the Laplander blade which may be different to the PG-72.
