I previously made a Strider&Microtech Stub Folding Knife（https://makerworld.com/zh/models/496550#profileId-410860） using Liner Lock, but this time I tried making an Extrema Ratio MPC with a Back Lock. Back Lock has better strength than Liner Lock.
MPC tactical folding knives are used to replace or assist straight knives, with beautiful lines and powerful structures. The cutting tools produced by Extrema Ratio are exquisitely designed and favored by tool users and collectors worldwide.

之前做了一把 Strider&Microtech Stub 的折刀玩具（https://makerworld.com/zh/models/496550#profileId-410860），使用的线锁，这次我尝试做了一把背锁的Extrema Ratio MPC。背锁比线锁有更好强度。

MPC 战术折刀是用来替代或辅助直刀的用途，线条十分优美，结构很强大。Extrema Ratio出品的刀具设计精良，被全世界刀具使用者和收藏者的青睐。
