retractable arm blades

Boost MeI really enjoy making quality models, and when you give me a little boost🚀 it helps motivate me to make even more. Thank you!Description The retractable arm blades are dual retractable blades hidden under your wrist. The blades pop out quickly and quietly by pulling the string held in your hand. The blades expand outward when pulled, creating a fascinating opening mechanism. The sleek and angular design makes this a fascinating and powerful weapon.   Supplies super glue string elastic/velcro  Assembly Step 1: cut a length of string. length depends on arm size and preference. Then tie the string to the handle. *tip: if string won't go through, add a drop of superglue to the tip of the string. that hardens it so it can go through easier. step 2: feed string through the hole on the big piece. it goes in from the bottom up. step 3: glue end of the string to the dot on the slider step 4: place the slider on the big piece, then the blades on the slider. make sure the slider is inside the square divot in the blades. it should all fit nicely. step 5: flip it over and put the pins in. The shorter pins go in the lower holes and go through the slider. A drop of superglue can keep the pins in.  step 6: add the arm band. Elastic or velcro works fine. Now you're done! :)
