Beginner flipping knife
Sang W.
A bit light weight and bulky for flipping. However I learned most of the beginner tricks with this knife and it survived being dropped on concrete several times. Definitely better than cheap copies made from pot metals. Now I use it when I go camping because it's easy to sharpen.
