Foot graters are not illegal to own or use on yourself, but razor-edged callus shavers, credo blades, and cheese-grater-style foot tools are banned for use by licensed nail technicians and cosmetologists in at least nine states. The line regulators draw is between tools that cut living skin and tools that buff away dead skin. What a salon can legally do to your feet depends on which side of that line the tool falls on, and on the state you’re in.
States That Ban Foot Graters in Salons
The states below have confirmed prohibitions on razor-type callus shavers, credo blades, and similar cutting tools in licensed cosmetology establishments. Other states may restrict these tools through broader sanitation rules, so a state’s absence from this list isn’t a green light.
- California. No establishment or school may have on the premises or use any razor-edged tool for callus removal.1Legal Information Institute. California Code of Regulations 16 CCR 993 – Prohibited Tools
- Delaware. Razor blades cannot be used to remove calluses during pedicures or other foot treatments.2State of Delaware. Delaware Administrative Code Title 16 4453
- Georgia. Salons cannot use razor-type callus shavers, credo blades, cutters, scrapers, or graters that abrade or remove layers of skin. Georgia’s rule is the only one that names graters explicitly.3Georgia Secretary of State. Georgia Administrative Code Chapter 240-2 – Violations and Fines
- Indiana. Razor devices used to shave, reduce, or remove calluses or corns are prohibited in salons.4Legal Information Institute. Indiana Administrative Code 820 IAC 3-1-16 – Manicurist Equipment; Salons
- Iowa. Licensed cosmetology and barbering professionals cannot remove skin with a razor-edged instrument.5Justia Law. Iowa Administrative Code Rule 481-940.6 – Licensure Restrictions Relating to Practice
- Missouri. Licensees cannot use, offer to use, or possess on salon premises any razor-type callus shaver, including credo blades or similar instruments.6Justia Law. Missouri Code of State Regulations 20 CSR 2085-11.020 – Cosmetology Sanitation Rules
- New York. Credo knives are prohibited, and their mere presence in a salon is treated as presumptive evidence of use.7Legal Information Institute. New York Codes Rules and Regulations 19 NYCRR 160.18
- North Carolina. Possession or use of razor-type callus shavers in a shop or school triggers an automatic $300 civil penalty per piece of equipment.8North Carolina Office of Administrative Hearings. North Carolina Administrative Code 21 NCAC 14P .0117
- Texas. Practitioners cannot use razor-type callus shavers designed to cut growths of skin, including credo blades.9Texas Department of Licensing and Regulation. Barbering and Cosmetology Health and Safety Rules 83.112
California, Missouri, and New York go a step further than the others by banning possession outright. An inspector doesn’t need to catch the tool in use. Finding it in a drawer is enough.
What Counts as a Prohibited Tool
The bans target tools with a razor edge or blade designed to cut skin: credo blades, cheese-grater-style callus shavers, and hollow-blade scrapers. Most states use umbrella phrases like “razor-type callus shavers” or “razor-edged instruments” that cover the same equipment even when a specific product name isn’t listed.
Non-cutting tools generally remain legal in salons. Pumice stones, ceramic foot files, emery boards, and electric buffing devices smooth skin through abrasion rather than slicing, and they stay standard equipment during professional pedicures. If a tool has a blade that shaves off skin, assume it’s prohibited in a licensed setting. If it sands or buffs, it’s typically fine. If your technician reaches for something that looks like a kitchen grater, that’s a fair moment to ask what it is.
Penalties Salons Face
Fines vary by state and escalate with repeat offenses. California can penalize an establishment or an individual operator up to $500 for a prohibited razor-edged tool.10Board of Barbering and Cosmetology. Do Not Use These Tools Georgia runs a graduated scale of $25 for a first offense, $75 for a second, and $300 for each additional violation.3Georgia Secretary of State. Georgia Administrative Code Chapter 240-2 – Violations and Fines North Carolina imposes a flat $300 per prohibited item.8North Carolina Office of Administrative Hearings. North Carolina Administrative Code 21 NCAC 14P .0117
Missouri treats the use of a prohibited callus shaver as grounds for professional disciplinary action under its licensing statute, which can include suspension or revocation of a license.6Justia Law. Missouri Code of State Regulations 20 CSR 2085-11.020 – Cosmetology Sanitation Rules
Using a Foot Grater on Yourself
State cosmetology bans regulate licensed professionals performing services on clients. They do not restrict what you buy or use in your own bathroom. Foot graters, credo blades, and callus shavers are legal to purchase and use on yourself anywhere in the United States.
The safety concerns that motivated the salon bans still apply. It’s easy to cut too deep on skin whose thickness varies from spot to spot, and an open wound on the foot is a straightforward path to infection. If you use one at home, work in gentle passes rather than trying to remove a callus in a single session.
A Serious Warning for People With Diabetes
Diabetic neuropathy can prevent you from feeling how deep a blade is cutting, and poor circulation can turn a small nick into a serious ulcer. The American Diabetes Association advises against cutting calluses or corns yourself and recommends letting a healthcare provider handle removal. For routine care, a pumice stone on wet skin followed by moisturizer is a safer choice.11American Diabetes Association. Foot Complications
Checking Your State and Reporting a Salon
Your state’s Board of Cosmetology or Board of Barbering is the definitive source for what’s prohibited where you live. Most boards publish their sanitation and equipment rules online. A search for your state name plus “cosmetology board prohibited tools” usually gets you to the right page faster than the board’s own navigation.
If you see a technician using what looks like a razor-edged tool on a client, you can file a complaint with the state licensing board. Most boards accept complaints from anyone, not only the client who received the service. Complaint forms are typically available on the board’s website, and staff will decide whether to investigate.
