5 ways to see if your knife is sharp.

Now your blade must always be sharp, but how do you know if your knife that you bought on amazon after watching a movie is really sharp?.

A sharp knife is safer than what in your hands than a knife that is not sharp.

Sounds strange to you?

Sharp blades are easier to use and are more reliable for doing cutting operations and for controlling what you are doing because they require less force to achieve the same effect so they gain in sensitivity and precision.

They do what you want and do it well most of the time.

Paper test

The paper test is as famous as the trademark round hole on Spyderco’s knives.
