it is not triangular but a blade of Diamond section, both sides have a Long flattened ridge, running in the middle of the blade.
With this type of blades, often , at one side the ridge extends over the ricasso and at the other side the ridge stops before the ricasso, so that the thumb can be placed on a flat surface.

best,
