Why don't truck stops sell wire rope cutters?

The wire rope seals can be easily cut with dykes. I can cut up to 3/8'ths wire rope with just dykes and a hammer.

 

How many cuts before it dulls?

 

Well it is not good for it but most of the time we used oxy/acetylene to cut the wire ropes unless we were pulling line off the crane to run through a wedge socket then we'd have to use wire rope cutter which looks like a steel block with a striking head and sharp hardened blade and you'd take an 8 pound sledge hammer and beat on it til it cut through the 1 inch wire rope nice and clean.

As far as the 3/8ths stuff, most of the time that wasn't going to be used for anything special so a lot of the time you just hold the wire over the edge of an H beam and beat on it with your hammer to cut through it or like I said use the torch.

 

That's a diskus lock, not a puck. Though there's much much better disc locks than that one. The puck is a circular chunk of steel with a hole in one side and a straight bar that crosses it to close.

What diameter of wire rope are you going to cut?

 

It's vacuum insulated dewar flasks as far as I know. Hard to transmit heat through a vacuum.

 

Montgomery Trap and Supply Company has a pair of cutters like I have been using on the trap line for decades. I have made plenty of snares and drowner cables and they cut just as good as day one. They claim to cut up to 3/16", but I think if you nipped at it a couple of times it would work. It's the pair with the bent handles. The nice part is they are made in the USA.

 

They are still only as good as the hasp you put them on. Locks only prevent honest people from breaking in. Those can be twisted off with a pipe wrench.
