A wonderful small knife

This is a good ring knife for the value. Looks great as well and it flips out smoothly. Be careful when handling it, it is pretty pointy.

Perfect size and feel!

Great small ring with a hidden knife

Perfect ring

Don’t let the word ring fool you. It’s a solid knife. Great design and quality. It won’t break and definitely last forever.
