Knog 20 function multi tool



Chic, charming emergency tool, but a tad pricey and lacks leverage

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Knog’s twenty- function multi tool crams a phenomenal amount of useful stuff into a very confined space and is just the thing for best bikes loving to travel light. Good quality steel won’t chew delicate fasteners but it wouldn’t be my first resort for group rides and for all their charms offer limited leverage when tackling stubborn fasteners…assuming the crank bolt adaptor hasn’t vanished down the sofa.

Despite measuring a mere (47x47x20mm) it tips the scales at a jersey pocket stretching 192g and for these reasons belongs in the seat pack. Finished in a rich anodised blue, the hinged design opens in a way that reminded me of the puzzle in the Hell-raiser films, revealing the usual suspects (2-8mm Allen keys, torx wrench, flat and Phillips screwdrivers) which sit in their own channelled bed of medical grade silicone-simply pressing the logo on the reverse prises them out ready for action. The magnetised base consists of a chain splitter; 15mm pedal/ track nut wrench coupled with smaller 8,10,13mm sizes for mudguard eyebolts, rack, cable anchor bolts and other fiddly fasteners. There’s even a bottle opener for the post ride tipple.

These are made from forged chrome vanadium for durability and corrosion resistance and seem very hardy. Accurately machined, they’ve failed to slip or round off fixings even under provocation and aside from being every bit the executive toy, the chain tool and spoke keys could make the difference between riding and the long walk home. Access to awkward areas such as around the front mech and bottle cage mounts is easier than the pocket workshop variety but pieces measuring two and a half centimetres long make for very slow progress- especially crank bolts so not the ideal race companion either and the extensions pieces are too readily lost by the roads or trailside. I'd score this particular battle of form versus function a draw, but there is no doubt that usability suffers to some degree in the interests of aesthetics.

Tell us how the product performed overall when used for its designed purpose

Despite bijous dimensions, the Knog is quite nice to use and more accessible than some of the really macho multi-tools-e.g roadside front mech tweaking. Good quality materials mean they shouldn'r round off, or damage fastners at the crucial point, although you'd be there until Christmas trying to tighten a loose 8mm crank bolt. However, all of this misses the point. For group rides and/or more everyday fettling, the larger type tools are more practical but those loving pretty design and minimalism won't be disappointed.

Tell us what you particularly liked about the product

Lovely design, detailing and solid construction.

Tell us what you particularly disliked about the product

Nothing when when judged as a bit of designery kit - pure function is not what these are about. Oh and it is expensive

Did you enjoy using the product? Yes

Would you consider buying the product? Possibly

Would you recommend the product to a friend? Yes, if they were looking for a super stylish, compact tool.

Overall rating: 6/10

A tricky one to mark - I like this tool and probably those who are likely to buy it are probably willing to trade some leverage for it's looks. On emotion I'd give it a seven, but judged purely as a tool (which is surely all about function) it's a 6
