How to Make Your Jantz Kitchen Blade Food Safe

How to Make Your Jantz Kitchen Blade Food Safe

A kitchen knife is one of the most-used tools in the home, so it needs to be more than sharp. It needs to be clean, durable, corrosion-resistant, and built with materials that can safely stand up to food prep, washing, and regular use.

At Jantz Supply, our kitchen blade blanks are made from stainless cutlery steels selected for knife applications. But the blade is only one part of the finished knife. To make a kitchen knife that is ready for food prep, you also need to think about the handle, adhesive, pins, finish, coating, and care routine.

Here is a simple guide to building a kitchen knife that is easier to keep food safe.

What Does “Food Safe” Mean for a Kitchen Knife?

For a kitchen knife, “food safe” means the finished knife should not contaminate food during normal use. It should be:

• Made from materials suitable for food contact
• Resistant to rust and corrosion
• Smooth enough to clean thoroughly
• Free of cracks, gaps, pits, or open seams that can trap food
• Finished with products that are safe for the intended use
• Washed, dried, and maintained properly

No coating, wax, handle material, or steel grade can make up for poor construction or poor cleaning. A food-safe kitchen knife is the result of the whole build working together.

Start With the Right Blade

A good kitchen knife starts with a blade steel that can handle moisture, acids, salt, and repeated washing. Stainless cutlery steels are popular for kitchen knives because they offer better corrosion resistance than simple carbon steels.

Jantz kitchen blade blanks are made from stainless cutlery steels and provide a strong starting point for food-prep knives. These steels are suitable for kitchen blade use when they are properly heat treated, finished, cleaned, dried, and maintained.

That last part matters. Stainless steel is corrosion-resistant, not rust-proof. Even stainless blades should be cleaned after use and dried before storage.

Finish the Blade Smoothly

A blade used for food prep should have a smooth, cleanable finish. Deep scratches, heavy scale, pits, or rough grinding marks can hold moisture and food residue.

Before using the knife in the kitchen:

1. Remove grinding residue, buffing compound, oil, and dust.
2. Smooth and finish the blade surface.
3. Clean the blade thoroughly.
4. Make sure there are no chips, cracks, loose coatings, or rough spots.
5. Dry the blade completely before final assembly or storage.

A clean finish is not just about looks. It makes the knife easier to wash and maintain.

Consider Gator Skin for Added Blade Protection

For makers who want an added layer of protection, Gator Skin Nano Ceramic Coating is a good option to consider for kitchen blades.

Gator Skin is described as an FDA-compliant, food-safe, non-stick nano-ceramic coating suitable for cutting instruments and blades. It is designed to reduce drag, help prevent corrosion without the need for oil, and make treated surfaces easier to clean.

That can be especially useful on kitchen knives because food prep exposes the blade to water, salt, acidic foods, and repeated wiping.

Important note: Gator Skin can help improve the blade surface, but it does not automatically make the entire finished knife food safe. The handle, adhesive, pins, seams, and final construction still matter.

Choose a Handle Material That Can Handle Kitchen Use

Kitchen knives get wet. They are exposed to oils, acidic foods, soaps, and repeated handling. Because of that, handle material matters.

Synthetic handle materials such as G10 are popular for working knives because they are strong, durable, and resistant to moisture compared with many natural materials. G10 is made from woven fiberglass fabric and epoxy resin, making it a practical choice for kitchen builds.

Natural materials like wood, bone, and horn can make beautiful handles, but they require extra care. Many natural materials are porous and can crack, warp, or absorb moisture if they are not properly sealed and maintained.

For a kitchen knife, choose handle materials that are:

• Stable
• Moisture-resistant
• Comfortable to grip
• Easy to clean
• Properly sealed or finished
• Free of cracks, voids, and open grain

If using wood, consider stabilized wood or a properly sealed finish to help reduce moisture absorption.

Seal and Protect the Handle

Even a well-shaped handle needs protection. A good finish helps reduce moisture absorption and makes the handle easier to clean.

Wicked Waxis one Jantz option for protecting finished knives. It is described as 100% food safe and can be used on wood, steel, epoxy, plastic, and leather. It can help seal, shine, and protect the knife while helping make metal more rust resistant.

For kitchen knives, a thin protective coat can help with maintenance, especially on wood handles and exposed steel surfaces. Always apply finishes according to the product directions and allow them to cure or set fully before food use.

Use Adhesives Carefully

The handle should be firmly attached with no open gaps where food and water can collect. Epoxies and adhesives are commonly used in knife handle assembly, but they should be fully cured before the knife is used.

A food-prep knife should not have exposed sticky adhesive, soft uncured epoxy, or gaps around the tang and scales. After assembly, inspect the handle closely and sand or clean away excess adhesive.

We recommend West Systems Epoxy for kitchen knives as it is a marine-grade epoxy specifically designed to keep water out of cracks and seams.  Epoxy should cure at least 21 days to gas off and fully cure.  

A good kitchen knife handle should feel solid, smooth, and sealed.

Pay Attention to Pins, Bolsters, and Hardware

Pins, tubes, bolsters, and guards can add strength and style, but they should also be chosen with kitchen use in mind.

For food-prep knives, stainless hardware is often a practical choice because it helps reduce corrosion risk. Brass, nickel silver, and decorative materials may be appropriate for some builds, but makers should consider how the knife will be used, washed, and maintained.

Whatever hardware you choose, make sure it is flush, smooth, secure, and easy to clean around.

Avoid Finishes That Are Not Intended for Food Contact

Not every shop finish belongs on a kitchen knife. Some bluing agents, patinas, etchants, paints, oils, touch-up pens, and rust preventives may be useful for other knife styles but may not be appropriate for food-contact blade surfaces.

Before using any product on a kitchen blade, ask:

• Is this product intended for food-contact use?
• Does it fully cure?
• Can it chip, flake, smear, or transfer?
• Will it hold up to washing?
• Is it safe for the part of the knife where I plan to use it?

When in doubt, keep decorative or chemical finishes away from food-contact surfaces.

Clean Before First Use

Before the finished knife touches food, clean it thoroughly.

Wash the knife by hand with warm water and mild dish soap. Rinse well and dry immediately. Check the handle seams, pins, spine, choil, and heel of the blade for residue.

Do not put handmade knives in the dishwasher. Dishwashers can expose knives to harsh detergent, high heat, moisture, and impact with other utensils, all of which can damage the blade and handle.

Maintain the Knife After Use

Food safety does not end after the build. A kitchen knife stays safer and performs better with regular care.

After each use:

1. Wash by hand.
2. Rinse thoroughly.
3. Dry immediately.
4. Avoid soaking.
5. Store in a dry place.
6. Reapply protective wax or finish as needed.
7. Sharpen and inspect the edge regularly.

If you see rust, loose handle material, cracks, chips, or gaps, stop using the knife for food prep until it is repaired.

Simple Food-Safe Kitchen Knife Checklist

Before calling your kitchen knife finished, check the following:

• The blade is stainless or otherwise properly maintained for kitchen use.
• The blade surface is smooth, clean, and free of residue.
• The handle material is stable and suitable for repeated handling and cleaning.
• The handle is sealed or finished as needed.
• Adhesive is fully cured.
• There are no open seams or gaps around the handle.
• Pins, guards, and bolsters are secure and flush.
• Any coating or finish used on the blade is appropriate for food-contact use.
• The knife has been washed and dried before first use.
• The customer understands how to clean and maintain the knife.
