if you like the knife then it is good for you. but it is also extremely difficult to choose right knife, consider large varieties available.
this kind of small knives with claw like blades becoming very popular, I think there many reasons why.

also buying knife of reputed company is a good choice always you cant go wrong with Kabar or TOPS knife
this two knives made by TOPS are great self defense tools
