CannonKeys has just announced upcoming availability of a new low-profile keycap profile for custom keyboard enthusiasts. The PFF profile—Penguin Flat Foot—designed by prolific designer, Matt3o and commercialized by CannonKeys, and manufactured by Keyreative, is, for all intents and purposes, a low-profile spin on the previously released PBS (Penguin Belly Slide) profile. Much like PBS, PFF prioritizes ergonomics, although, as Matt3o explains in his blog about the new profile, he opted to redesign the keycaps in order to work within the space constraints of low-profile switches.
The design itself features cylindrical front and back edges—like Cherry keycaps—with a spherical scoop on the top—like SA or Keychron’s KSA profile—which will likely result in a more distinctive separation between each key than typical cylindrical keycaps. Like PBS, PFF is universal height, which allows a great degree of freedom for those who enjoy custom keyboard layouts, like Dvorak, Workman, and Colemak. Matt3o showed off PFF with the Aperture Priority design, which previously showed up on PBS and on the Bullet Train keyboard, but the only PFF sets currently available on CannonKeys are WoB (white on black) and Verdant Retro. Both keycap sets have 1.5 mm wall thicknesses and dye-sublimated printing. The stems on the available kits are MX-style, meaning they will be compatible with Gateron Low-Profile and Kailh Low Profile Choc V1 switches. Pricing has not yet been announced for either PFF keycap set, but the creator notes that they will be cheaper than PBS, which retail for anywhere between $40 and $80, depending on the set and size.
