Winter is pretty mild here in the UK at the moment (although I'm touching wood when I say that of course) but around the world I see images of neck-deep snow, ice and general winter misery. Hopefully this should be of help. It's a salt scoop with a spring-loaded handle designed for scattering salt on frozen roads and pathways. Scoop up the salt, pull the handle and the flap at the bottom opens to allow the salt to run out. There is a grid at the bottom of the scoop to make sure that the salt comes out at a controllable rate and won't just drop on your feet.
I've tried this in action on the couple of days we actually got some frozen paths here, and it worked beautifully. Give it a go and let me know what you think!
