is this a common dagger?

May not be the most helpful of comments, but anyone else see resemblence between the hilt of the knife and a flinlock rifle stock? I know since I have a smaller screen size, when I first opened this post, without reading the title, I had thought it was going to be a rifle for discussion until I scrolled more to see the blade. Anyways, just a little .00001 cents to stir the pot so to speak.
