Seven point zero five ounces. In a market where every launch email leads with how light a knife is, the Kizer GPB1 leads with the opposite number, and that makes it worth a second look for anyone who thinks modern folders have gotten too fragile.
The Ki4473: 8.50-inch overall, 3.50-inch wharncliffe in CPM-S35VN at 0.12 inch stock, five-inch titanium handle, titanium frame lock, titanium pocket clip, custom pivot, tip-up carry, 7.05 ounces on the scale. Designer is John Gray, and the knife reads as an outdoorsman's folder rather than a desk toy — the wharncliffe gives you a straight cutting edge all the way to a low, strong tip.
The weight is not an accident of materials; it is a design decision. A five-inch handle in solid titanium with a full frame lock on a 3.5-inch blade is a lot of metal, and Kizer did not skeletonize it. What you get in return is a knife that does not flex when you lean on it, a lock face that has real mass behind it, and a handle long enough that the butt sits in your palm instead of your pinky. What you give up is pocket comfort — 200 grams in a jeans pocket is noticeable all day.
Cross-shop it against the Guru KI3504A2 at $91: also S35VN, also titanium, but a 2.97-inch sheepsfoot at 7.43 inches overall and far lighter. The Guru is the modern EDC reading of the same idea; the GPB1 is the older, heavier one. Against the Microlith at $104.30 you are looking at two knives that share steel and nothing else — 2.375 inches and 2.73 ounces versus 3.50 inches and 7.05 ounces.
Verdict: buy the GPB1 if you want a titanium S35VN folder that feels like it will survive being dropped on concrete and used with gloves on, and if you do not mind carrying the weight. Skip it if your daily carry is dress trousers, because this knife will pull them down.
