Several months ago I made a prototype tool that looks almost exactly like this. Unfortunately it doesn't work. The problem is that the space between the pin and the surface of the truck bolster is so slim that the claws need to be incredibly thin. Thin = weak. I've even tried hardened steel. Compounding this is the fact that some pins require a surprising amount of force to pull. Some slip out fine; others wind up bending or breaking the edges of the claws. Or, if the claws are just gripping the edges of the pin, the pin gets ruined.
So, if you're able to make this work, more power to you.

"Thin" in this case also means to an extent, sharp, adding the chance of going in to far and cutting into the pin. I suppose a simple adjustment could be added to prevent this, however that still leaves the problem of "thin = weak" (and surprisingly, even with hardened steel).
David, it's funny you should pipe in on this. As I was wasting the 5 minutes I took to draw the picture, I was thinking all along that this will give DKS an idea to go ahead and design/build one that actually works well. Sounds like you were ahead of all of us. It's a shame it didn't work out. Perhaps if you (we) give up on the idea of sliding under the pin, and instead grasping it in the fashion of the rusted screw pliers that Alex talked about, but still adding a way to re-insert the pin with the same tool (using the toothpick method)? Then again, just the pliers type might do, in which case Alex's find of the $30.00, Engineer Inc., PZ-57 Screw Pliers should do nicely.

I completed a functional prototype tool that actually works. So, why am I not marketing it? Cost to manufacture a custom, low-volume, complex precision tool will drive the MSRP up unreasonably high. I don't think there will be many Z Scalers willing to fork over $100 just to pull their truck pins.
And, lest anyone think I'm blowing smoke, here's a photo of the prototype tool. The Z-shaped rod is spring-loaded and fits into the hole in the pin; the two L-shaped rods slip under the truck bolster; and the two straight rods are actuated by a plunger to press against the chassis and yank the truck off, with the pin safely held in place on the truck.

I have used it on R.C. airplanes. I'ts very hard and strong. You can bend it, and grind it to
a flat edge. It might work for you. Just a thought. Good luck.

That's exactly what I used to make the prototype tool. The problem is not so much in designing a tool that works, it's in designing a tool that can be mass-produced economically.

Please dont try this use this for carjacking..I usually do did this after the MPS screwed up the inside of sombodys door while trying to use a slim jim for a half an hour. took me 5 minutes to make and use.
Anyway a loop of nylon line and a steel or copper tube might work too. picture those things animal control used to grab dogs with. Nylon line ran through a tube, looped back through and through a wooden bead that you would pull.This can pull the pins but not put them on.
