Be careful you don't rely on it, the triflex sucks bad for firesteel. The spine is tempered soft to be tough, but at the same time too soft to scrape firesteel reliably, you'll get one or two strikes before it rolls and won't produce any more spark.
I've
already got nearly 100 sparks out of it, so I'm not worried.

Besides, I can't imagine ever having nothing on me but the Mora (I usually have a dedicated striker and two or three knives).
