Beard Trimmers: 5 Fast Facts

Fact #1. They're closer to scissors than a razor blade. Conventional razors simply shear off hair. Even in multiple-blade variations, they act like knives. Beard trimmers use a motor to oscillate two parallel razors back and forth. That way, instead of slicing, they rapidly snip. This is what allows them to navigate sensitive and hard-to-reach spots.
Fact #2. The idea has been around since the 19th century. Before motorization ran rampant, barbers used manual clippers. They rapidly opened and closed their fingers to manicure their customer's facial hair. This was both exhausting and dangerous. But they did have some impressive beards then.
Fact #3. Current trimmer technology dates back to the 1920s and 30s. That period was marked by the Great Depression. Innovation wasn't exactly at its height. Nevertheless, four pioneers of this technology are still famous brands today. Those individuals went by the names Schick, Wahl, Remington, and Philips.
Fact #4. Their future might include electrolysis. Advancements over the last near-century have been slow. Trimmers started incorporating LED screens. They also upped the number and precision of settings. The next great innovation is likely to involve lasers. That's hardly a consumer-level technology now, but it might be soon.
Fact #5. Blades react differently based on skin type. For personal use, this isn't that important. Simply make sure no one with your skin type has had issues before buying. Professional use is a different story. If you are buying for a barbershop, research is important. Ensuring customers don't leave with a rash is worth the effort.
