EXPERT KNOWLEDGE LEATHER
What is leather and how is it made?
Leather is one of the oldest and most versatile materials known to mankind and remains a key material in high-quality craftsmanship and manufacturing to this day. It is produced by tanning animal hides, most commonly cowhide, transforming a naturally perishable raw material into a durable, flexible and hard-wearing material. This process gives leather its distinctive combination of strength, suppleness and longevity — qualities that clearly distinguish it from synthetic alternatives.
Tanning methods and their characteristics
The tanning method has a decisive influence on the quality and later use of the leather.
Vegetable tanning
Vegetable tanning is particularly widespread, using natural tannins extracted from bark or plant sources. This type of leather is firm, shape-retaining and develops a distinctive patina over time. It is ideally suited for traditional craft applications such as belts, bags or knife sheaths.
Chrome tanning
In contrast, chrome-tanned leather is produced much more quickly and cost-effectively. It results in soft, flexible materials commonly used in the fashion industry. However, it is less dimensionally stable and generally does not develop the same rich ageing characteristics as vegetable-tanned leather.
Our focus is on eco-tanned leathers
Subject to availability, our range also includes innovative processes such as olive leaf tanning or rhubarb tanning. These environmentally friendly alternatives are particularly skin-friendly and appeal to users who value sustainable materials and low-impact, non-toxic processing. This aspect is becoming increasingly important in high-end leather craftsmanship.
Leather quality criteria
A key quality indicator is the grain side—the natural outer surface of the hide. High-quality full-grain leather retains this surface intact and is considered particularly durable and hard-wearing. By contrast, corrected-grain leather is sanded and finished to achieve a more uniform appearance, but in doing so loses some of its natural strength and breathability.
Leather thickness is another important factor. Heavier leather, from around 3 mm upwards, is typically used for heavily stressed products such as belts or knife sheaths. Thinner leathers, on the other hand, are used for clothing, linings or fine leather goods.
Choosing the correct leather thickness is essential for both the function and durability of the final product.
Processing and working characteristics
Leather is an extremely versatile material to work with. Vegetable-tanned leather is particularly well suited to wet forming, embossing and tooling, which is why it is highly valued in traditional leathercraft. It can be dyed, waxed or oiled to achieve a wide range of surface finishes and protective properties.
Chrome-tanned leather is naturally softer and more supple, but less suitable for techniques that involve shaping or forming. The choice of leather type therefore depends heavily on the specific project and the desired material properties.
Leather care and longevity
To keep leather looking and feeling its best over the long term, regular care is essential. Conditioning with oils or waxes protects the material from drying out, preserves its suppleness, and builds resistance to moisture, dirt, and general wear. Well-maintained leather lasts for years — and develops character with age.

Sustainability and innovation
In recent years, sustainability has also become an increasingly important consideration in leather production. Environmentally friendly tanning methods, such as vegetable tanning or the use of innovative materials like olive leaves or rhubarb, offer an alternative to conventional industrial processes. These methods reduce environmental impact while improving the material’s skin compatibility.
Despite growing competition from synthetic materials, leather remains popular due to its durability, repairability, and distinctive ageing process. Over time, each piece develops its own patina, becoming truly unique.
DICTUM leathers & hides
Our leather range is specifically curated for demanding users in the field of leathercraft and features a selection of high-quality, process-oriented materials.
The focus is primarily on durable utility leathers such as cowhide, saddlery leather and robust buffalo hide, which are ideally suited for long-lasting projects such as knife sheaths, belts or sturdy bags. These leathers are typically vegetable-tanned, resulting not only in a particularly attractive patina but also in excellent mouldability and durability.
In addition to raw hides, our range also includes a wide selection of semi-finished products and accessories, including leather straps, pre-cut pieces, kits, as well as care and processing products. This creates a comprehensive offering that covers all stages of work, from material to finished surface, and is particularly appealing to ambitious craftspeople.
Summary
Leather: a timeless material with character
Leather is a complex, high-quality material whose properties depend greatly on origin, tanning method, and processing. Anyone who works with leather regularly soon appreciates how significant the differences between types can be.
Choosing the right leather makes all the difference to a project.
