Let's start with: what is leather edge creasing?
Leather edge creasing is a process used in the making of leather products to make the edges of the leather flat and attractive and to prevent their edges from stripping or fraying. It is one of the techniques commonly used by artisan leather craftsmen or leatherworkers.
It is common to join two pieces of leather edges in the process of making leather products, such as making bags, wallets, belts, etc. These edges need to be worked and finished to ensure that they are smooth, strong and have some decorative effect.

Trimming: cutting the leather edges to the desired shape and size, making sure they are aligned.
Sanding: The edges are sanded using sandpaper or a sanding wheel to make them smooth.
Coloring: The edges are dyed or stained as needed to match the overall color of the piece.
Crimping: This is the most critical step in the process. Using a crimping tool or an edging machine, the heat-treated edges are pressurized to flatten them, and the adhesive binds the edges together during the heating process, enhancing durability.
Edging: Decorative edging, such as metal trim, leather cords, etc., can be added to the edges as needed.
Waxing and Polishing: Finally, the leather edges can be waxed and polished to add shine and protection.
Through these process steps, the leather edges can be effectively protected and decorated, so that the final leather products have higher quality and visual appeal.
As the image below demonstrates.
Creasing leather involves using a metal-tipped tool with two prominent lines and a central groove. One side of the tool protrudes slightly more than the other, serving as a guiding edge. This guide runs along the leather's edge, ensuring a consistent distance is maintained throughout the process.
With pressure alone, or pressure with heat, it will leave a line in the leather a specific distance from the edge. This could be 1mm, 2mm or more depending on the creaser you have.
As a handcrafted leather artisan, the choice of an electric or manual creaser depends on your specific needs and work style.
There are various types of edge creasers (Edge Creasers), which can be categorized into the following categories based on different designs and features:
Manual Edge Creaser: A manually operated edging tool that usually includes a graduated line or guide groove that helps the craftsman maintain a consistent distance between edges. Manual crimpers are usually simple to use and are suitable for small-scale and simple leatherwork.
which is most commonly a metal (usually steel) creaser tip that has been attached to a wooden handle.‘Manual’ comes from the need to manually heat up the metal head yourself, usually by a spirit lamp, or a small blow torch if you’re in a hurry!
Electric Creaser: edgebanders with an electric drive for increased productivity. They are usually equipped with adjustable heating temperatures to allow adaptation to different types of leather. Motorized creaser machines are suitable for leather goods with thick or complex edges and are suitable for mass production.
Adjustable creaser: this type of crimper has adjustable scales or guide slots that allow the craftsman to choose different pressing distances and angles as required. This allows for more flexibility and creativity in different projects.
Multi-functional creaser: some creaser are designed as multi-functional tools that can be used with different attachments or graduated heads to realize more leather crafts, such as edge sanding, edging, inlays, etc.
Hot edger creaser: This type of edger creaser uses thermal heating technology when pressing the edges to make the edges flatter and stronger and to provide a better bond. Hot edging creaser machines are usually used to work with thicker leathers or complex edge designs.
While the manual creaser is undoubtedly more budget-friendly and straightforward, it does demand a certain level of expertise to gauge the appropriate heat effectively.
The dilemma is one of cost, with electric edge creaser offering easier availability, but at a higher cost. On the other hand, they may be attracted to the more affordable manual edge creaser, which require more experience for optimal results.
Especially for those on a budget, it's a good idea to allocate dedicated time to practicing with a manual edge creaser after purchasing a set. Through consistent practice, beginners can gradually acquire the necessary skills and techniques to achieve satisfactory results. This approach not only hones their craft, but allows them to gain valuable experience without a large initial investment.
By striking a balance between practice and potential future investment, beginners can embark on their leather making journey with confidence and steadily improve their craft.
