Please check the exact delivery contents with the seller before purchasing if needed. Frequently Asked Questions How small is the SOG Centi I? The closed knife length is about 50 mm and the weight is around 13 g. This makes it suitable for carrying on a keychain, in a small pocket, or as a backup knife in hiking gear. Does the SOG Centi I blade lock in the open position? No. The knife uses a slipjoint mechanism that applies spring pressure to the blade but does not lock it rigidly. Avoid applying force in the opposite direction to the blade while cutting. Can the knife be opened with one hand? No. The blade is opened using a nail nick and is designed for controlled two-handed opening. What tasks is the SOG Centi I suitable for? It is suitable for cutting packaging, tape, paper, and thin cord. The knife is not intended for prying, chopping, splitting wood, or other heavy-duty tasks. When is the SOG Centi I the right choice? The SOG Centi I is a good choice if you want the smallest and lightest cutting tool possible that can always be attached to your keychain or gear. It's suitable for users whose typical needs are limited to cutting packaging, tape, and thinner cord, and who do not wish to carry a full-sized pocket knife. If you need a longer blade, a more secure grip, or a locking mechanism, choose a larger SOG pocket knife with XR lock, such as the Terminus XR. If you need multiple tools, pliers, and screwdrivers, the SOG PowerPint is a more practical alternative. Expert recommendation The biggest advantage of the SOG Centi I is that it is small enough to actually be carried every day. The approximately 13-gram weight and 50 mm closed length mean that the tool won't noticeably weigh down your keychain or take up significant pocket space. It's ideal for situations where you need to open a package, remove tape, or cut thinner cord. However, keep in mind the slipjoint mechanism: the blade does not lock in the open position. Always use the knife for straight cutting and avoid applying pressure that could close the blade toward the handle. Due to its small construction, the Centi I is not suitable for prying or heavy woodwork. After exposure to moisture or dirt, clean and dry the knife and occasionally add a drop of suitable oil to the joint. This will keep the blade action smooth and the stainless steel construction in good condition. A mini pocket knife that's always at hand The SOG Centi I combines a 35 mm stainless steel blade, keychain-friendly design, and a weight of just about 13 g. It's a practical backup knife for users who want to always have a small cutting tool at hand.
