Very good knife for the money, but it can be a bit scary on the foot in case the rope gets tangled in the knife, you might lose it. There is a solution for this too: you can put a rubber band in the two holes it has under the plastic to secure it. I will upload photos soon

This review is about a variation of the product

Very sharp knife and very high quality, I have been using it for 5 months in diving, with a good wash at home every time you return and proper handling, I have not lost anything yet. Also, the case holds the knife and it cannot escape.

It rusts on the first and second dive.
The case requires attention because it doesn't close easily and you easily lose the knife. Overrated

The quality of the plastic is unacceptable, with no elasticity, just like the knife which resembles a kitchen knife with a coating. For use in underwater fishing, it should have been much better, especially for use in the weight zone where it will endure a lot of strain. As a second backup for a leg or arm, it's okay
