Bombardier stilettos

[broadaxe]

Here is a nice one from Oriental-Arms, bought by a good friend of mine.

We had this dagger replicated by a knifemaker, with interchanging blades (they were taken from fencing foils therefore have square cross section rather triangle one): one has a sharp point and the other has a safety button for training. Here is a photo, and another photo of a similar one from an old booklet in Italian, dealing exclusively with gunner's stiletto.
