Small knife

A cute knife, which can really do some cut, like open a box. Alll things can be printed, except the T blade ( last picture), pin_b1 is optional.

Please glue the blade, the safe needs support, shell_a may needs brim, no screw required.

一把可爱的小刀，可以用来拆快递。要买一个刀片，再用502大法。pin_b1 是可选的，目的是减小转轴的框量。保险要支撑。shell_a 最好用brim，不需要螺丝。
