It's still the same plastic knife just with S30V. For the same price you can pick up other knives with better materials... such as the Spyderco ParaMilitary 2... The Axis lock is reeeeally gimmicky.
"Better" materials don't make a better knife. The excellent design of the Griptilians make them fantastic, practical working knives. They are very strong yet light, relatively inexpensive, easy to open and close, and great cutters.
I have been a wholetime firefighter for 13 years. Over those years I have carried many different knives while on duty - SOG, Spyderco, Chris Reeve, Rick Hinderer, William Henry, Al Mar, Kershaw etc
I now carry a full sized Grip and 5 Rescue Hook in my firejacket and a Mini Grip in a pouch on my uniform belt. The knives I carry on my uniform belt rotate through many different makes and models (though usually Benchmade Axis Locks) but the knife in my firejacket is
always a 551 Griptilian or 552 RSK Mk1.
As to the Axis Lock being "reeeeally gimmicky"... It locks the knife securely open and also maintains pressure to help keep the knife closed. It is reliable and easy to manipulate, even while wearing thick firefighting gloves. It's a work of genius, not a gimmick.
