The chasen is the tool the Japanese tea ceremony was built around, and it is still the standard way to get matcha to dissolve properly. Dozens of hand-split tines move through the bowl at once, breaking the powder apart and folding air in as they go, so you finish with an even green foam rather than grit at the bottom of the cup. This one is carved from a single piece of sustainable bamboo. The outer tines curl outward and the inner tines stand in a cone at the centre, the two-ring structure that gives a chasen its spring and lets it work in a shallow chawan as easily as in a mug. Getting the most out of it Soak the tines in warm water for about a minute before the first use, and briefly each time after that. Warm bamboo flexes, dry bamboo snaps. The tight curl you see out of the package will relax and open as it softens, which is the whisk reaching its working shape. Sift your matcha, add a little hot but not boiling water, and whisk briskly in a zigzag or W motion rather than stirring in circles. Lift the whisk at the end to pull the foam up. Rinse under warm running water only. No soap, no dishwasher, no scrubbing. Shake off the water and stand it tines-up on a whisk holder, or upright on the counter, until it dries all the way through. Leaving a chasen damp and lying on its side is what shortens its life more than anything else. A chasen is a wear item, and this routine is what keeps the tines springy and the fan shape intact. Pairs naturally with ceremonial-grade matcha, a chawan bowl, a bamboo scoop and a whisk stand. Hand wash only. Bamboo grain and colour vary slightly from whisk to whisk.

• Froth Without the Lumps: Dozens of fine bamboo tines move through the bowl at once, breaking the powder apart and folding air in as they go. You get an even green foam in seconds instead of grit sitting at the bottom of the cup.
• Soak Before First Use: Rest the tines in warm water for a minute before you whisk. Dry bamboo is brittle and snaps; warm bamboo flexes. The tight curl relaxes and opens as it softens, which is the whisk reaching its working shape.
• Rinse, Stand, Dry: Warm running water, no soap and no dishwasher, is the whole cleaning routine. Stand it tines-up on a whisk holder so it dries through between bowls, which is what keeps the fan shape and the spring in the tines.
• No Cord, No Batteries: A light wrist motion does the work, so there is nothing to charge, plug in or store on the counter. The same tines blend cocoa, hojicha or a cornstarch slurry into liquid without leaving dry pockets behind.
• Carved From One Stalk: Each tine is split by hand from a single piece of bamboo, then curled outward with an inner ring standing in the centre. It is the tool the tea ceremony was built around, and an easy gift for a new ritual.
