As others have mentioned, pliers have many uses in the wilderness no matter if you are car camping or hiking way off the beaten path not to be carrying them.

As to the weight concerns, really? I am no weight weenie by any means, but these types of statements make me wonder. How much extra does a pliers equipped multi-tool weigh as compared to a similar equipped SAK or other similar too? I would venture to say a few to 5 ounces at best. And if someone is really that concerned about carrying those few ounces then perhaps it would be better to lose a lb or so of body weight before one goes out hiking...
