Spring Loaded Arm Blade without Drawer Slide
Can anyone help me with instructions on how to do a spring loaded hidden arm blade without using a drawer slide? Looking for something a bit more refined. Also, I am looking not for it to use as is, but to spring out the blade and then be able to grasp it with hand and remove it to use.
So I guess, more of a spring loaded holder for a knife, because really, trying to use an arm blade like this to do any real damage in an actual fight, would be difficult.
