The Henson Ti22 is painstakingly machined from grade 5 titanium (Ti-6Al-4V) and comes in at double the weight of the Henson AL13. Titanium threads have a higher likelihood to bind or gall, so we made the extra effort to machine Nitronic 60 stainless steel threaded inserts that make for a better feel when tightening and loosening the handle. Titanium is an exotic metal known for its strength and durability. This makes the Ti22 a truly "buy it for life" safety razor. And with the rave reviews our razors already get, you know you're buying something of exceptional quality and performance.
