Conceived as ultra light flat pedals for road riders who choose not to ride clipless, the KCNC Knife pedals are an interesting proposition. Primarily aimed at urban commuters finding the interaction between traffic, lights and clipless pedals (or toe clips) too perilous, but who want more security of foot placement than is offered by plain flat pedals without the additional weight of studded MTB flats.
This is a truly tiny pair of flats. At 170g for the pair, inclusive of optional studs, they weigh a good deal less than even the lightest SPD pedals, with no additional weight penalty from cleats to bear in mind. These aluminum alloy pedals are also lighter than any other flats I could find on the market, with the exception of KCNC’s own titanium version of the same pedal (just 150g for the pair).
About the same size as smaller SPD pedals, these aren’t going to immediately appeal to everyone, although with the studs on, they sit securely and comfortably underfoot, providing a surprisingly sure ride, even out of the saddle working hard. The ride feel was distinctly akin to that with SPDs set loose. Without the studs, they’re still pretty secure, although some slippage did occur. The studs are easily attached, with a handy tool provided to tighten them, but they are quite aggressive, and would hurt if shin and pedal were to collide. That said, the security they give means that this is less likely anyway!
A good looking pedal too, available in four colours (gold, black, blue, red), that will enable ride pimping for that crucial urban cool.
Given the price, I’d say you’d have to be a pretty committed flat fancier and fast paced commuter to make the most of these, but they are a light, effective and attractive antidote to the perils of being clipped in at junctions and in traffic.
Super light, effective and surprisingly supportive flat pedals. Good looking too, but you are paying for the ultra low weight.

Well machined and nicely finished.
Surprisingly secure underfoot, offering a ride not dissimilar in feel from loose SPD pedals. With studs, even felt secure while out of the saddle.
Studs are replaceable.
Good riding comfort, wouldn't be so comfortable if your shin met with the studs.
An investment, but such low weight comes at a premium.
