A plain guide to reading utility knife size figures: folded versus overall length, blade length, and why a single number rarely describes the whole tool.
Size figures describe different states of the knife
A utility knife size is not one number. Listings usually give either a folded size, an overall length, a blade length, or some combination, and those figures describe different things. A folded length tells you how much space the closed tool takes in a pocket or drawer. An overall length describes the tool extended. A blade length describes the cutting edge or the blade as a whole, depending on the convention the listing uses.
Because these are different measurements, they cannot be compared directly with each other. A knife stated as 92 mm folded and another stated as 94 mm overall are not 2 mm apart in any meaningful sense; one figure is for the closed tool and the other for the open one. Before comparing two utility knives, check that both listings give the same kind of measurement.
The Compact Folding Utility Knife with Keyring & Replaceable Blade is stated as approximately 92 mm by 26 mm when folded. That is a folded footprint, not an overall length, and the listing does not give an open length or a blade length. So it can be compared with another folded-size figure, but not with an overall-length figure.
What a folded size does and does not tell you
A folded size is the most useful figure for carry and storage questions. If you are checking whether a knife will sit in a pocket, a tool pouch or a glovebox compartment, the folded dimensions are the ones to use. The 92 mm by 26 mm figure for the folding utility knife describes that closed footprint.
What a folded size does not tell you is how the knife feels in hand, how much blade is exposed when open, or how it balances. Those are not documented in the supplied facts, and they cannot be derived from the folded dimensions. A compact folded figure is a storage and carry measurement, not a statement about grip or cutting reach.
The listing also states a built-in keyring hole for attaching the knife to keys, a lanyard or a bag. That is a carry arrangement rather than a size figure, and it does not change the folded dimensions.
Blade size and blade system are separate questions
Utility knives commonly use replaceable standard utility blades, and the blade size is usually a property of the blade type rather than of the knife body. The folding utility knife listing states a replaceable standard utility blade and describes replacement as quick and tool-free, supplied with five spare blades and one user manual. It does not state a blade length or a maximum cut depth.
That gap matters if you are sizing a knife for a specific cutting job. A folded size and a blade type do not add up to a cut-depth figure, and the listing does not provide one. If a particular depth or blade length is critical, that is a question for the seller rather than something to infer from the folded dimensions.
The listing also does not describe maintenance or service details for the knife body beyond blade replacement. Where that information is missing, it is missing; do not assume any part other than the blade is either serviceable or permanently fixed.
A practical way to compare utility knife sizes
First, list the size figures each candidate gives and label each one as folded, overall or blade. Only compare like with like. Second, decide which figure matches your actual question: carry and storage point to folded size, reach and cutting position point to overall or blade length. Third, note what is missing rather than filling it in.
For the folding utility knife, the documented size fact is the folded footprint of approximately 92 mm by 26 mm. That is enough to judge pocket and drawer fit against another folded figure, and not enough to judge open length or blade reach. Treating it as the whole size picture would overstate what the listing states.
Is a utility knife's folded size the same as its overall length?
No. A folded size describes the closed tool, while an overall length describes it extended. The two cannot be compared directly, and a listing that gives only one of them does not establish the other.
What size is the Compact Folding Utility Knife with Keyring & Replaceable Blade?
The listing states approximately 92 mm by 26 mm when folded. It does not state an open length or a blade length, so the folded footprint is the only size figure the supplied facts provide.
Does a folded size tell me how much blade is exposed?
No. Folded dimensions describe the closed tool only. Blade exposure and cut depth are separate figures, and the folding utility knife listing does not state either.
