When I had a 72 Bronco and did a lot of off-roading I made a 'sand wedge'
1/4" steel plate cut in a triangle, 2 1/2' steel bar (1") welded to plate (full length), a 5 lb. mandrel on bar to use as a slide hammer with a 'T' handle at top of bar and a heavy ring welded at top of plate
I would drive the wedge at an angle into the sand.......hook up my wench cable to the ring and pull truck towards the wedge....repeat as necessary until out.
Got me out of several spots where nothing else was around to strap to.
Looked like a short shovel.......just really stout
