Collapsible Ceramic Utility Knife 19cm

The Ruth's sister collapsible ceramic utility knife measures 19 cm fully extended and folds for compact storage. Its 7.8 cm oxide-ceramic blade resists corrosion, bacteria and odour transfer while staying sharp longer than steel. The knife is intended for kitchen, office or school tasks such as slicing fruit, vegetables, fish, meat or paper.

Folding mechanism and blade care

The knife collapses by pivoting the blade into the plastic handle, reducing the length to roughly the 11.2 cm handle size for safe carrying. No tools are required to open or close it. Ceramic blades can chip if twisted, pried or used on frozen foods and bones; hand washing is recommended to preserve the edge and prevent handle stress.

Before ordering

Verify that a 7.8 cm blade length suits the cutting tasks you have in mind, as the knife is not designed for heavy-duty chopping or prying. Confirm you are comfortable with a random handle colour, since the supplier ships assorted colours without choice. Ensure you can store or carry a 19 cm tool when open and an 11.2 cm tool when folded.

Questions about this item

How do I know the ceramic blade is working as intended after I unfold it?

The 7.8 cm blade should slice paper, fruit or vegetables cleanly without tearing and leave no metallic taste or odour on the food.

What comes in the box and what must I buy separately?

The box contains one 19 cm collapsible knife with a ceramic blade and plastic handle; no sheath, sharpener or cutting board is included.

Which version should I choose since the colour is random?

Only one version exists — model B2RD7HH800271 — so you receive a single knife in a randomly assigned colour.
