TinyEdge

Most electric shavers live and die by their batteries: forget to charge before a trip and they become dead weight. TinyEdge, a Kickstarter project, removes the battery entirely. The maker says the shaver draws power over USB-C straight from a smartphone or power bank, so there is nothing to charge and no remaining-charge indicator to check before use.

Light, small and built from titanium

Dropping the battery also cuts weight. The maker puts TinyEdge at 68g, roughly a third of a typical electric shaver, which it says usually weighs over 200g, and describes it as small enough to slip into a pocket or a gap in a bag. The body uses titanium, which the maker chose for its strength, low weight and corrosion resistance on a device meant to travel often.

Magnets for easier cleaning

A magnetic construction lets the cover and blades detach and reattach without fuss, according to the maker. The aim is to make post-shave cleaning simpler, since conventional shaver heads tend to trap hair in small crevices.

• A blade for cutting longer and coarser stubble
• A blade for precise finishing on short hair
• A gentler blade intended for sensitive skin

Those three blades make up what the maker calls a 3-in-1 structure, designed to handle different beard types and skin conditions and to speed up a morning shave.

NFC, and plans beyond the shaver

TinyEdge also includes NFC. The source frames its uses as possibilities rather than delivered features: a companion app that could log shaving frequency and beard growth, suggest when to shave, or flag when blades need replacing, along with future software updates. The maker also points to environmental benefits from avoiding lithium-ion batteries, and suggests the same battery-free approach could extend to products such as electric toothbrushes or nail care devices.
