Gerber Fastball Folding Wharncliffe Lock Knife (MagnaCut)
Utility like never before. Genuine CPM MagnaCut in an affordable package.
The Gerber Fastball is an American-made everyday carry folding knife that brings together a compact design, excellent materials and exceptionally quick deployment. This version pairs the Fastball's proven design with a CPM MagnaCut Wharncliffe blade, giving you a premium blade steel without moving into the usual premium-price territory.
Made in the USA, the Fastball is designed around practical everyday utility rather than unnecessary bulk. The aircraft-grade aluminium handle keeps weight down, while the ball-bearing pivot and precision detent give the knife an exceptionally smooth, fast action.
CPM MagnaCut Blade
The headline feature is the CPM MagnaCut stainless steel blade.
Developed by metallurgist Dr. Larrin Thomas and introduced by Crucible Industries in 2021, MagnaCut was specifically developed to address the traditional compromises between toughness, corrosion resistance and edge retention found in stainless knife steels.
In practical terms, MagnaCut offers an excellent combination of:
- High toughness
- Strong corrosion resistance
- Good edge retention
- Excellent general-purpose performance
- Easy maintenance compared with many high-performance steels
The Fastball uses a modified Wharncliffe blade profile with a flat grind, giving it a practical cutting edge particularly well suited to everyday utility tasks.
Fast, Smooth Deployment
The Fastball's name isn't entirely marketing department poetry.
Its ball-bearing pivot provides smooth blade movement, while the precision detent produces Gerber's distinctive fast "lightswitch" deployment. For a UK-legal folding knife, it offers an unusually quick and positive opening action without relying on an assisted-opening mechanism.
The liner lock provides a secure locking interface when the blade is deployed, while the easy-off liner lock release makes closing the knife straightforward.
Lightweight Aluminium Construction
The handle is manufactured from aircraft-grade aluminium and finished in a distinctive blue anodised finish.
At just 79g, the Fastball is light enough for everyday carry without feeling like a disposable lightweight knife.
A multi-position pocket clip provides flexibility for carrying the knife in the position that suits you, while the compact closed length keeps it easy to carry.
