Hand-sewn vs Machine: Which Is Stronger?

Hand stitching on leather collars and leashs: why it's stronger than machine sewing


If you're looking for truly durable leather Collars or leashs, there's one detail that makes all the difference:


how they are sewn.


At NUVIK we work with both leather collars and leashs sewn by hand, because it's not just about aesthetics… it's about safety.


What is hand stitching in leather?


Hand stitching in leather is done using the traditional double-needle technique (saddle stitch).


👉 Important:


A single thread is used, with one needle at each end.


This allows:


Passing the thread through both sides of the leather
Crossing each stitch within the material
Creating a much stronger bond


Why is hand stitching stronger than machine sewing?


Here's the real difference 👇


🔹 Machine stitching
Uses an interlocked thread system
If the thread breaks → the seam can open
Less tension control
🔹 Hand stitching (saddle stitch)
A single continuous thread with two needles
Each stitch is locked inside the leather
Tension is manually adjusted


👉 Result:


Much more durable and reliable collars and leashs.


Even with a single thread, the way it's sewn makes the structure much more solid.


Why is this key in Collars and leashs?


In products like:


Leather Collars
Leather dog leashs
The stitching withstands:
Strong pulls
Daily use
Water, mud, and wear-and-tear
If the stitching fails, everything fails.


That's why at NUVIK we use this system in both:
collars and leashs, without exception.


Why is it more expensive?


Because the process is entirely manual:
Marking the sewing line
Making each hole one by one
Passing the thread stitch by stitch
Manually adjusting tension

 This takes a lot of time and precision.

It cannot be sped up without losing quality.


 Waxed thread: key to durability


We use high-strength waxed thread, which:
 Reduces friction
 Protects the thread
 Improves grip on the leather
 Increases durability
 Additionally, it helps seal each stitch.
 Total precision in every piece


Hand sewing allows:


Reinforcing critical areas (rings, buckles, handles)
Controlling each stitch
Preventing series failures
 Each collar and each leash are unique.
 Why does NUVIK hand-make collars and leashes?


At NUVIK, we're not looking for speed.


We want the product to last.


That's why:
All collars and leashes are hand-sewn
We use premium waxed thread
We work with high-quality leather
We follow traditional processes
👉 Because our products are made for real use.


Patience, consistency, and positive reinforcement are your best allies. Each dog is unique, and tailoring strategies to their personality will make a difference.


Hand sewing with continuous thread (saddle stitch) is one of the most durable techniques in leatherwork.
More time, more work, higher cost…


but also:


more safety, more durability, and more quality.
