Chef's knife, anything you can use in a kitchen
Dirk, bowie or fighter without a guard lessen it's one of them Scottish Dirks cause the other ones usually ain't got one
It doesn't matter what you call it, what matters is what the customer sees. I'll give an example told to me by my teacher. He had a nice knife at blade, mammoth ivory, blued fittings and was calling it something like a vest pocket gambler's bowie. Some lady asked how much and paid 4 figures for it, he was handing her the sheath and she said for him to keep it cause it was the best looking steak knife she'd ever seen..... so to repeat myself...... doesn't matter what we call it, what we think it is, what matters is what the customer thinks.
