I recall years ago researching a tulwar that had been labeled a Sikh weapon, and I had been inquiring numerous sources to find exactly what indicators or markings would define a weapon as Sikh. I eventually contacted the author of a book on the Sikh Faith with the history of their warriors. When I inquired and asked that question the author replied, "if a weapon was used by a Sikh, then it is Sikh", and suggested that they used many weapons, not necessarily marked or of specific form.
With that I realized a key factor in studying weapons in general, that often what identifies a weapon historically with any group may not be distinguishable by its appearance or origin.
Perhaps what is sinister here is not the dagger itself
