Tanner Leatherstein explains the 5-pillar system for judging leather quality, with a star chart and handwritten notes in the background.

One of the most frequently asked questions I get from you is simple yet profound: How can you tell the quality of a leather product? With the holiday season approaching, my studio is stacked with a queue of products ready for dissection. But before diving into evaluating them, I want to give you a clear look into my thought process and the framework I use. If you’ve watched my past videos, you might already know about the five-pillar system I rely on to assess leather goods. In this post, I’ll go deeper, providing context so you can use it as a comparative tool, helping you understand quality relative to other products.

In this blog, we will answer the following questions:


  • What are the five pillars of the Leatherverse, and how do they define leather quality?
  • How can you evaluate leather using raw hides, tanning, and finishing techniques?
  • What role do craftsmanship and structure play in the durability of a leather product?
  • How does design influence usability, originality, and overall product sophistication?
  • How can the Leatherverse Matrix help you determine whether a product is fairly priced or overpriced?

The Five Pillars of the Leatherverse

I like to think of leather quality assessment as a star system—a “Leatherverse star”—where each pillar represents a point on a star. The five pillars I focus on are Leather, Hardware, Craftsmanship, Structure, and Design. Each pillar is graded on a scale from one to five.


  • Leather and Hardware: These form the foundation of any leather product because they are the materials that make the product functional and durable.

  • Design: At the top, design acts as the guiding principle that unites all other elements into a cohesive, standalone product.

  • Craftsmanship and Structure: These are the side pillars, equally essential, as they determine how well a product holds together, both in form and function.

Each pillar has its own set of sub-pillars to guide evaluation.


Hardware: Material, Coating, and Design

Hardware is assessed similarly, with three core elements:


  • Material: Metals like brass, steel, zamak, or even plastic, depending on the product.

  • Coating/Finish: This affects longevity and resistance to wear.

  • Design/Engineering: The functionality, usability, and aesthetic of the hardware.

A well-crafted product uses high-quality hardware that complements the leather and design.

Craftsmanship and Structure: Two Pillars Each

Craftsmanship focuses on both the choices and the execution:


  • Choice of Techniques: How edges are finished, how stitching is applied, and how layers are assembled. These choices determine quality and longevity.

  • Execution: Once designed, the product must be executed consistently to maintain balance and function.

Structure Involves:

  • Engineering Complexity: How sophisticated the internal engineering is to maintain the intended shape.

  • Material Selection: Non-leather and non-hardware materials that form the product’s backbone. Both factors influence how the product holds up and functions.

Design: Originality, Usability, and Sophistication

Design combines three foundational elements:


  • Originality: How creative and unique the shape and concept are.

  • Usability: Practical functionality, including aesthetics and everyday usability.

  • Sophistication: The complexity of the design and how successfully it achieves a high-end or unique result.

These three sub-pillars collectively determine the product’s overall design score.

Scoring and the Star System

Each pillar is evaluated, and sub-pillars feed into a score from one to five. The result is a “star” or spiderweb chart representing the balance and sophistication of the product. A top-tier leather good scores a five in each category, producing the perfect Leatherverse star.

Introducing the Leatherverse Matrix: Price vs. Sophistication

Once a product’s star is determined, I use a “Leatherverse Matrix” to assess fair pricing. On the Y-axis, sophistication ranges from simple rugged goods to trophy-level bespoke pieces. On the X-axis, pricing multipliers reflect cost and value, usually starting at a 2x cost for basic products.


For example:


  • Entry-level rugged products (like Portland Leather) may cost $30 to make, with a 2x multiplier selling for $60. Fair pricing for their market and materials.

  • Sophisticated luxury pieces (like bespoke Ferragamo or trophy-level exotic leather goods) might cost $3,000 to make, but a 10x multiplier pricing them at $30,000 is fair given craftsmanship, materials, and uniqueness.

This matrix helps buyers determine if a product offers fair value or if they’re overpaying for branding.

Putting It All Together

By assessing leather, hardware, craftsmanship, structure, and design, then mapping it on the Leatherverse Matrix, you can make informed decisions about what to buy and understand the “why” behind a product’s price. Some products may appear expensive but are justified by sophistication, while others may be overpriced relative to their quality.


This methodology allows for transparency, comparison, and smarter purchasing decisions. It’s how I approach dissecting and grading leather goods in my studio, and it’s a system you can apply when shopping.

Final Thoughts

Understanding leather quality is more than just touch and look—it’s about materials, engineering, design, and value. By learning how to grade products across these five pillars, you can spot true craftsmanship, make fair-value purchases, and appreciate the artistry behind the leather goods you love.


Stay leathertained, and keep searching for those hidden stars in the Leatherverse!
