“A sharp knife is a safe knife,” says Joshua “Jhun” de Andres, owner of Kuya Sharpens. It only takes a light touch to guide a properly-sharpened knife, while dull knives require much more force to cut through an object, increasing the likelihood and severity of an injury. “If you slip, that’s a lot of force that is now going into your finger, your hand, and that’s where it becomes extremely dangerous.”
De Andres started sharpening knives as a meditative practice during a time of personal grief, a way to zone in on a task with a useful and satisfying outcome. “[It was a] reminder to myself that you can fix something that’s broken and give it purpose again.” Once he ran through his own collection of knives, he started asking friends and family if he could sharpen theirs. When he’d sharpened everyone’s knives he could think of, he started posting videos on TikTok, where his first professional chef customer found him: Chef Tanner Stanich, chef de cuisine at Michelin-recognized Bib Gourmand Mabel’s Gone Fishing.

“That’s when things really started to take off,” he laughs. He uses whetstones rather than motorized belt sanders to sharpen, which gives him the ability to make microadjustments during the process for a more customized and controlled result. Whetstones also preserve steel more efficiently than other mechanical processes, which are faster, but take off more of the knife’s edge in exchange, reducing the lifespan of the knife.
Learning how to master whetstones takes a lot of time and practice, and while de Andres specializes in sharpening Japanese knives, he’ll sharpen a knife from anywhere. “Every knife deserves to be sharp,” he says.
Japanese kitchen knives are designed for extremely specific purposes: there’s a knife to break down a fish (deba), cut through boneless raw fish for sushi and sashimi (yanagiba), slice vegetables (nakiri), carve meat (sujihiki), debone poultry (honesuki), and even knives only the executive chef can use (kiritsuke). Few other culinary cultures utilize such ultra-specialized tools, and Japanese steel is prized for its extreme hardness and ability to maintain a razor-thin edge for decades when properly cared for.
De Andres is still figuring out different ways to expand his business: hosting workshops at Home Ec on Adams Avenue, creating knife restoration tutorials, and launching private lessons, all while continuing to sharpen knives people bring to him or even send from across the country. And he knows that for both home cooks and professional chefs, sharpening a knife that may have cost hundreds of dollars on a whetstone can feel overwhelming. Will I ruin it? Will I break it?
“You’re most likely not going to break it,” he promises. “But you are going to make it yours, and you have to kind of be okay with that.” Knives age and change just like humans do. Sharpening is an essential part of maintenance, and shaving away the dull edges to restore a shine takes care. And de Andres cares a lot.
“It’s just been really life-giving to me,” he says. “I know it seems really silly that taking a knife and putting it on a whetstone can change your perspective on how you view the world, but for me, it came to me at a time when I needed it most.”
