KUKI4473: Ki4473 John Gray GPB1 Folding Knife
Kizer Cutlery
The Ki4473 GPB1 folding knife by Kizer Cutlery is a collaborative project between Kizer and custom knifemaker John Gray. The GPB1 or Gray's Pocket Brute 1 is based off his custom Thuck design which pairs a slender handle with a wide, harpoon-like blade which is more than enough to get any job done. The 3.5" drop point blade is made from CPM-S35VN stainless steel with dual angled thumbstuds for more positive purchase. The bearing pivot system allows for smooth blade opening, as with all Kizer knives. The ergonomics of this milled titanium handle are absolutely fantastic and really lock this knife into your hand extremely well. It features an overlarge Philips head pivot (just like the custom), lockbar overtravel prevention mechanism, replaceable steel insert, lanyard slot, pocket clip and is a great sized folder for every task that is built with a quality anyone can appreciate.

Kizer uses high-tech wire EDM machines to cut the parts. This method is slower than laser or water jet but Kizer feels quality is worth the wait. Each component in Kizer knives is precision machined and engineered to the finest tolerances. The final fit, finish, action, and sharpness of each knife is achieved entirely by hand, employing the irreplaceable craftsmanship developed by generations of cutlery masters. Dedicated craftsman honoring the long-term goal of making the best knives possible is what Kizer brings to you.

Frame Lock
Frame Lock
Developed by Chris Reeve, it functions like a liner lock but the lock is comprised of one of the handle scales. It's an extremely strong and easy to manipulate lock.
Pocket Clip
Pocket Clip
Includes a pocket clip for easy accessibility and a more secure carry.
A tougher steel than S30V, it retains the excellent corrosive properties and ability to take an edge, but improves on the ability to hold that edge.
Titanium Handles

A nonferrous metal, it's prized for its high strength to weight ratio and is often used on higher end knives.

Cons: None
A very nice piece
I have a custom made Thuck by John Gray which is very fine--so I was curious about this considerably more affordable collaboration with Kizer. It is similar--continuing some of its best qualities: the unusually large triangular-shaped blade, the elegantly curvaceous and comfortable titanium handle, and the nice heft. Yes, you can easily carry it in your pocket. Comes with a nice pouch.
