Input:
This is a new production knife and not the one pictured in the add. The main differance being the file in the picture, which is an actual file made of tool steel. The knife I received has a piece of stainless steel thats grooved to look like a file on the sides, with saw teeth underneath. I ordered this knife thinking it was the model in the picture because the retail stores sell the same thing I received in the mail. Dissaponted in this product to say the least.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: D: negative
