Product Safety

Last updated October 14, 2026

A safety razor is a simple tool with a very sharp edge. Handled the right way, it is calm and predictable. This page brings together the safety information for every KATA product. The quick start guide in the razor's box comes first: please read it before you shave with the razor for the first time, and keep it.

For every product

• Our products are made for adults, and you must be 18 or older to buy them. None of them is a toy.
• Keep the razor, the blades and used blades out of reach of children and pets, ideally in a high cabinet.
• Use each product only for what it is made for, as described in its instructions.
• Stop using a product that is damaged, and contact us.

Double-edge blades

Warning: blades are very sharp, on both long edges. Keep out of reach of children.

• Hold a blade by its short ends only, never along the long edges.
• Unwrap blades slowly, on a dry, well-lit surface, and take out one blade at a time.
• Never leave a loose blade on a counter, the edge of a sink or in the shower. A blade is either in its wrapper, in the razor or in your blade bank.
• Do not use a blade that is bent, chipped or rusty. Put it straight in your blade bank.
• Replace the blade as soon as it starts to pull. A dull blade makes you press harder, and pressure is what leads to nicks.

Changing a blade

1. Work over a dry surface or a folded towel, not over an open sink drain.
2. Unscrew the handle and lift the top cap off, holding it by its sides, not by its front edge.
3. Lift the used blade by its short ends and put it straight in your blade bank or closed metal container.
4. Place a fresh blade on the base plate, centered, holding it by its short ends.
5. Put the cap back, then screw the handle in until it is snug.
6. Look at the head: the blade should sit straight and show as an even thin line along the edge. If it does not, take the razor apart and seat the blade again.

Never try to change a blade while the razor is assembled, and never put your fingers on the front edge of the head.

Shaving

• Do not share your razor with anyone, even after cleaning: a razor can carry traces of blood and skin between people.
• Do not shave over broken, cut, sunburned or irritated skin, or over a spot, a mole or a wound. Shave around it.
• Use a good lather, short strokes and no pressure: the weight of the razor is enough. Take your time on the first few shaves.
• If your skin reacts, stop and let it rest. If the reaction does not settle, see a doctor.

First aid

• A small nick: rinse it with cold water and press a clean, damp cloth on it for a few minutes until it stops.
• A deeper cut: press firmly with a clean cloth. If it does not stop after 10 minutes of steady pressure, if it is deep or gaping, or if it was made by a rusty blade, get medical help.
• A child and a blade: if a child has handled a blade or the razor and may be hurt, or may have swallowed a blade, get medical help right away. In an emergency, call 911.

Traveling with your razor

Here is what the US Transportation Security Administration (TSA) says about safety razors and razor blades when you fly from a US airport:

• Blades go in checked baggage only. Razor blades that are not in a cartridge, such as double-edge blades, are not allowed in carry-on bags. Keep them in their wrappers and their box in your checked bag, so they cannot hurt the baggage handlers and inspectors who may open it.
• The razor may go in your carry-on bag without its blade. Take the blade out before you reach the security checkpoint. TSA officers are not allowed to remove it for you.
• The travel sleeve covers the head of the razor, but it does not change these rules. A razor with a blade in it belongs in your checked bag, sleeve or not.
• The TSA officer at the checkpoint makes the final decision. Rules change from time to time, so check the TSA's razor blades and safety razor pages before you fly.
• Other countries and some airlines have their own rules. Check them before an international trip.

Getting rid of used blades

A used blade is still sharp. Thrown away loose, it can hurt the people who collect and sort trash and recycling. So:

• Put each used blade straight into a blade bank (a small closed container made for used blades) or a closed metal container, such as an empty metal can with a lid that you can tape shut. Label it "Used blades".
• Keep the container closed and out of reach of children.
• When it is full, tape it shut and dispose of it the way your city or county asks: some accept a sealed container with household trash, others ask you to bring it to a metal or household hazardous waste drop-off. Your local waste service can tell you which.
• Never put a used blade loose in household trash or in a recycling bin, and do not put a container of used blades in curbside recycling unless your local service says it accepts it.
• When the razor, the brush or the stand reaches the end of its life, take any blade out of the razor first, then follow your local rules for small household items with metal parts. The packaging can go out with your regular paper or trash, following local rules.

Looking after your razor

• After each shave, rinse the head under warm running water, shake off the water and let the razor dry upright, in its stand if you have one.
• From time to time, take the razor apart (blade out first, as described above), rinse each piece and let them dry before you put it back together.
• Clean it with water and a little mild soap. Do not use abrasive pads, harsh cleaning products or a dishwasher, which can mark the finish.
• Do not drop the razor or knock the head against the sink. A bent cap or base plate can hold the blade unevenly. If the head looks bent or damaged, stop using it and contact us.

The shaving brush

• After shaving, rinse the brush under running water until the water runs clear, shake it out gently and let it dry standing on its base, in the open air.
• Do not store it wet in a closed cupboard, a drawer or a bag, and do not dry it with a hair dryer or on a radiator.
• Keep the brush for your own use, for hygiene.

The razor stand

• Drop the razor in handle first, head up, so the head dries in the open air.
• Place the stand on a flat, stable surface, away from the edge where it could be knocked off, and out of reach of children.
• Keep the counter and the stand dry: wipe away standing water after shaving.

The travel sleeve

• Let the razor dry completely before you slide the sleeve over the head, and keep the sleeve itself dry.
• Slide it on and off by the open edge, with your fingers away from the front of the head, where the blade edge is.
• The sleeve covers the head, but it is not a lock, and a razor in its sleeve still holds a blade: keep it out of reach of children too.
• Wipe the sleeve with a soft dry cloth and keep it away from heat.

Reporting a safety concern

If you think one of our products is unsafe, stop using it and email us at goualafabiola06@gmail.com with "Safety" in the subject line, the product name, your order number if you have it, and photos if you can. We treat safety messages as a priority. If anyone has been hurt, get medical help first.

You can also report an unsafe product to the US Consumer Product Safety Commission at SaferProducts.gov.

Recalls and safety notices

If we ever need to recall a product or share a safety notice, we will email everyone who bought it, using the email address given with the order. We will also publish a notice on this page and on the product page, explaining clearly what to do and how we will put it right, at no cost to you. Product recalls in the United States are also listed on the Consumer Product Safety Commission website.
