Input:
After waiting ten days to receive this product, I was very disappointed with the quality and workmanship.

First of all, the pocket clip was missing a screw and only held loosely in place by the remaining screw.

The handle appeared to be fairly thin flexible plastic, and the blade locking mechanism was similar to that used on $10 hardware store models.  Fortunately, there was a small thumb clip to prevent the locking mechanism from failing as it can on cheaper knives.

The blade was also quite dull by comparison to Buck or SOG knives.  Overall, I would rate the knife as far inferior to the $38 Buck knife sold on Amazon in materials, workmanship and quality.  Very surprising for an $80 knife, and very different from the product description.  Returned to Amazon for refund within an hour of receipt.

Options:

E: very negative
Answer: E: very negative
