Global Usuba Vegetable Knife GS-83 (13cm Blade, Stainless Steel)

What's the difference between this usuba and a nakiri knife?

The Global GS-83 usuba features a thinner blade profile compared to nakiri knives, making it more suitable for precision vegetable work. Traditional usuba knives have a single-bevel edge, but this Global model uses a double-bevel 15-degree edge for easier maintenance. The 13cm blade length and compact handle make it more manoeuvrable than larger nakiri knives, particularly for detailed herb work and delicate vegetable preparation.

How do I properly maintain the Cromova 18 steel blade?

Hand wash immediately after use with warm water and mild detergent, then dry thoroughly with a soft cloth. Never put Global knives in the dishwasher as this can damage the edge and handle. Regular sharpening with a Global or Minosharp sharpener maintains optimal performance. Store in a knife block or magnetic strip to protect the edge. With proper care, the Cromova 18 steel will resist rust and maintain its sharpness for years.

Why does the handle contain sand and how does this affect performance?

The hollow handle contains precisely measured sand to counterbalance the blade weight, creating perfect equilibrium. This balance reduces hand fatigue during extended use and provides superior control over cutting motions. The sand is permanently sealed inside the handle and won't shift or leak. This innovative design feature is what makes Global knives feel so comfortable and controlled compared to traditional tang-construction knives.

Is this knife suitable for tasks beyond vegetable preparation?

Yes, whilst designed primarily for vegetables, the GS-83 excels at multiple tasks including herb chopping, sashimi preparation and light meat work. The sharp 15-degree edge and compact size make it excellent for detailed work requiring precision. However, avoid using it for heavy-duty tasks like bone cutting or frozen foods, as this can damage the fine edge. It's particularly effective for garnish preparation and delicate protein work.

How does the 13cm blade size compare to other Global vegetable knives?

The 13cm GS-83 is more compact than the popular GS-5 vegetable knife, making it ideal for users with smaller hands or those preferring greater manoeuvrability. The smaller handle diameter allows for more precise grip control, though some users with larger hands may find the GS-5 more comfortable. The blade length is perfect for most home kitchen tasks whilst remaining manageable for detailed work that larger knives cannot perform effectively.

What makes the 15-degree edge angle special?

The 15-degree convex edge creates a much sharper cutting angle than typical Western knives (which use 20-25 degrees). This acute angle allows the blade to slice through vegetables with minimal resistance, creating cleaner cuts that preserve cell structure and reduce bruising. The convex shape also means the edge wears more slowly than straight bevels, maintaining sharpness longer and requiring less frequent sharpening maintenance.

Can this knife be resharpened and how often is sharpening needed?

Yes, the Cromova 18 steel can be resharpened using Global sharpeners or professional services. With regular home use, sharpening every 3-6 months maintains optimal performance, though this varies based on usage frequency and cutting surface. The hard steel holds its edge exceptionally well compared to softer stainless steels. When sharpening, maintain the 15-degree angle to preserve the blade's cutting characteristics and performance.

Is there an age restriction for purchasing this knife?

Yes, this product requires age verification as it's restricted to buyers over 18 years old. Online purchases require age verification checks and delivery drivers may request photographic ID with date of birth confirmation. This is a legal requirement for knife sales in the UK. Valid ID such as a driving licence or passport may be required upon delivery to complete the purchase.
