channel lock pliers are a poor replacement for tongs. do yourself a favor and buy a set of tongs. if you go into any blacksmith shop you will see racks filled with tongs. channel locks are in the toolbox for working on the car.
btw railroad spikes make poor knives at best.
I am guessing that you are somewhat of a beginner (you didn't say) so no offense meant, but if you're going to go down this road you might as well start in the right direction.
soon you will be making your own tongs.
