I was reading this article in the UK Daily Telegraph when I encountered the phrase "maraging steel." The article mentions it only briefly, describing it as "maraging steel, a light but high-strength form of the metal."

A few minutes' Googling uncovered several mentions of this metal. It is, apparently, used in the manufacture of golf clubs and fencing foils, for instance.

This link gives some technical specifications.

Have I missed something? Does anyone use this in knives? Or is it well known and useless in crafting blades?

Reading through the link you provided .. the steel is good in strength (ductility) but not hardness, 53RC only can't be tempered and hardened with normal process applicable for knives... so it's good for stick, structures and other similar purpose, but not knife...
 
A few years ago it was really popular for the faces of golf clubs, drivers in particular. What was promoted then was its exceptional ability to 'spring back' from the ball's impact, which I believe would come from a high tensile strength. A point was also made that they contained little to no carbon but were still very hard.

Other than that I don't know much about it.
 
Maraging steels were developed 40 years ago.They combine martensite transformation ( iron -nickel martensite not iron-carbon) and age hardening => mar-aging. They are high strength and tough. Expensive and not a good choice for blades. I looked on the internet too recently and about the only listings were golf clubs !! International Nickel never developed the alloy for that !
