Strength Tested: How Tang Types Hold Up Under Hard Use

Posted by Sam Flaherty on

If you've ever wondered why some knives hold up better under hard use than others, you're in the right place. Today, we're looking at tang types – a crucial factor in determining a knife's strength and resilience. From full tang to partial tang, we'll examine how these designs impact your knife's ability to handle tough tasks like prying and chopping. 

So, whether you're a seasoned chef, an outdoor lover, or simply someone who values quality tools, follow to learn factors that contribute to the durability of a knife.

What Is a Full Tang Knife?

A full tang knife isn't just a regular blade – it's a powerhouse. Imagine the blade material extending all the way through the handle, creating a seamless integration of strength and functionality. This design ensures that the blade and handle work together as one, providing unique balance and resilience. When you're dealing with tough tasks like prying or chopping, a full tang knife is there, ready to tackle the challenge without hesitation.

Difference between Full Tang and Partial Tang Knives

Now, let's compare the full tang with its counterpart, the partial tang. Imagine the partial tang knife as a lighter, more agile choice. Unlike its full-tang sibling, a partial tang knife has no blade material extending through the handle. Instead, it balances functionality and convenience, making it suitable for everyday tasks where brute force isn't required. 

While both types have their strengths and weaknesses, understanding their distinctions helps in selecting the right tool for the job.

Performance Testing: Prying and Chopping.

Durability is the backbone of any reliable tool, especially in demanding situations. Knives can undergo various durability tests to ensure they can withstand the challenges they'll face in the field.

Prying Tests

Prying is a common task where the strength and resilience of a knife's tang type truly come into play. Knives are subjected to prying tests to assess their ability to exert force without breaking or bending. This involves applying pressure to the knife blade in different directions to simulate real-world prying scenarios.

Chopping Tests

Chopping is another fundamental task that knives are expected to perform efficiently. Chopping tests evaluate a knife's edge retention, blade geometry, and overall performance when tackling dense materials.

Performance Evaluation

During these tests, knives are evaluated based on their ability to maintain sharpness, resist chipping or deformation, and handle repeated stress. With their robust construction, full-tang knives excel in prying and chopping tasks, offering unmatched durability and stability under pressure.

  4. Hammered ‘Jamon’ Slicer: Designed for precision slicing, the Jamon Slicer excels in carving meats, slicing sushi, and tackling large cuts of meat easily. Its long, slender blade (278mm) and low profile (20mm) make it the perfect tool for achieving paper-thin slices.
  5. Hammered Veg Chopper: As the name suggests, this knife is a powerhouse for chopping vegetables. With a longer blade length of 210mm and a height of 50mm, it effortlessly tackles everything from onions and tomatoes to larger vegetables like cabbage and watermelon.

Blade Perfection: Three Steps to Excellence

The Osaka Collection knives undergo a precise three-step process for blade perfection: Slice, Slide, and Separate. Firstly, the blade's VG10 steel edge boasts a sharp 15-degree angle for effortless slicing. 

Secondly, 33 layers of steel on each side allow ingredients to glide smoothly, enhanced by a layer of nickel for visual appeal. Finally, hammered ripples near the spine create air pockets, aiding in ingredient separation. This process ensures exceptional cutting performance and durability, making Osaka Collection knives indispensable in any kitchen.

Artistry and Practicality of Blade Ripples on Osaka Knives

Blade ripples, or "tsuchime" in Japanese, are the mesmerizing undulating patterns on Osaka knives achieved through meticulous hammering, known as the "hammered finish." Beyond aesthetics, these ripples serve a practical purpose by creating tiny air pockets that reduce food sticking to the blade during slicing. 

This functionality enhances the dining experience, allowing for smoother, cleaner cuts. Crafting these ripples requires skilled metallurgy and precise hammering techniques, ensuring the blade's practicality and longevity. Thus, the art of blade ripples adds beauty to Osaka knives and elevates their performance, making them indispensable tools in the kitchen.
