ony one thought or heard of people doing this? you basically put a blade/talon on the ground by a tree and tie a string around the trigger wrap it around the grip then tie it to something else like a tree...i didnt think it up but im gonna test it out
it would be better do this with an imagine or something...put it on full auto and then when someone steps on the string or something to pull the trigger they will get plastered in paint
a talon or blade would be a bad idea. It would only be up to one shot to hit them. It could work if they was walkign. but if they are running they wont trip the wire. So just get a cheap electro adn it should be fine. But as said above, you could just get a mine for cheaper price.
