Mantis knives makes one hell of a heavy duty folder. Part pry bar and knife. It's made of the S30V steel. It is one heavy knife. If you want a light girley knife this is not for you. The knife is the MT-4 folder. I will try to include the link to the knife below so you can see it. The price is a little salty, but then again so is any knife worth having. The lock is as tight as can be and sometime takes both hands with pressure to release the liner lock. I hope to field test the knife but want to carry it on duty with me as I am a police officer. It should take anything I can dish out.

Not all of there knives are this heavy and expensive. They make a wide variety of knives and knives for different jobs and for different budgets. About time a company did this. My hats off to the Mantis knife company.
