DescriptionQAALF1: Quartermaster Knives ALF-1 Awesome Little F***er, BiznassQTRM5TR Knives
Since the introduction of the ALF-1 & ALF-2, it's been reported that QTRM5TR is the only USA manufacturer outside of the Orthodontic Instrument Industry who is currently using Beta-Titanium on any cutting blade. To them, that spells revolutionary. It's important to Quartermaster Ordnance MFG. that they stay informed with regards to new technologies and processes, and the use of Beta-Titanium Alloy in edged tools is certainly one of them.
It's a known fact that "Titanium" does not hold an edge very well on its own. But if you care to dive a little deeper into the details, you find that this known-fact refers to the use of Alpha-Alloy Titanium, the commonly known 6-2-4-2 titanium, surgical grade 5 that is being used on many USA manufactured frame locks. Quartermaster Ordnance Mfg. is using a proprietary blend of ASTM Grade 21, an alloy from an entirely different family. Sure it has all of the great features of the alpha-alloy, it's lightweight, it's strength, it's rigidity, but Beta-Alloy comes with the added bonus of being fully heat-treatable and approximately 10% more dense than the typical titanium seen today. Never before has it been possible to claim a Rockwell Hardness of 57-58 on a Titanium blade, but thanks to QTRMSTR Ordnance Mfg. in 2014, we can. The difference between the tools is self-explanatory. One has been given the monicker "BizNass" the other "Purdy." One should stay with you while you're executing your days duties, the other should remain with you for the smooth, evening hours.
