We already have four or five Sawyer Minis, but I'm considering getting a Sawyer Squeeze in addition because the Squeeze is more durable and lasts longer.
I have two plastic Spark-Lites, but I'm considering a brass Spark-Lite because the brass version is more durable and will last longer. If you recall, I ruined a plastic Spark-Lite years ago when I dropped it in the fireplace.
In addition to the above examples, what other durable survival gear should be considered? By "durable," I mean something that should last for years.
