Trainer blade (no sharp edges)

I found that the blade of the other butterfly knife was hard to print, and not very appropriate for outdoor use. So I adapted the design to make a fish-bone type shape, so it just look's like a harmless toy. This is also very easy to print. To Install this Unscrew the two screws on the top sides and then pull them out, insert the blade and if you have Super Lube Oil use that along the process, Insert the screws back in for the results. Addons Super lube - - This should make flipping smoother. Benefits to this design - Is heavy (easier to flip) - If you get your finger in between it doesn't hurt - Makes a clicking sound when flipping, its very nice to hear -- Thanks for reading!
