At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

This is especially useful for creating strong, durable seams in heavy fabrics or on items that will undergo a lot of wear and tear.

  • A walking foot is a type of presser foot that features an additional set of feeding mechanisms on top of the fabric. Unlike standard presser feet that rely solely on the machine’s feed dogs to move the fabric beneath the needle, the walking foot grips the fabric from above and moves it in sync with the feed dogs below. This dual feeding action prevents slippage and ensures that all layers of fabric are fed evenly through the machine, which is particularly helpful when sewing thick or textured materials.

The simplicity of the mechanics also means there is less that can go wrong, giving artisans confidence in their tools.


  • These industrial-grade sewing machines are built robustly to withstand the harsh marine environment. They are often equipped with stainless steel components, designed to resist corrosion from saltwater and humidity. The needles are strong enough to pierce through heavy canvas or Dacron, materials commonly used in sail construction. Some advanced models even feature computerized controls for precision stitching, allowing for intricate patterns and designs.

  • 2. Walking Foot A walking foot, or a feed dog system, can be invaluable when sewing fur and leather. This feature helps to feed the materials evenly through the machine, minimizing the risk of shifting. It works by moving the upper layer of the fabric in sync with the feed dogs beneath, which is particularly useful when working with slippery and bulky materials.

  • 4. Reduced Labor Intensity The physical strain associated with hand stitching leather can be significant, especially for large projects. By utilizing stitching machines, artisans can reduce their manual workload, allowing them to focus on more creative aspects of their craft.


  • Before you start sewing, you need to select the appropriate twin needle for your project. Twin needles are available in different widths (the distance between the two needles) and thicknesses. A wider spacing is ideal for techniques like pintucks, while a narrow spacing is better for sewing on knits and lightweight fabrics. Additionally, consider the size of the needle itself; a thicker needle is better for heavier fabrics like denim, while a finer needle works well with more delicate materials.


  • In the ever-evolving world of packaging and sealing, efficiency and convenience are paramount. One of the most innovative tools to emerge in recent years is the handheld bag closer.

  • One key feature that sets these needles apart is their larger eye. This not only accommodates heavier threads but also makes threading easier, reducing frustration and potential damage to the thread. The sharp point of a heavy duty needle is designed to penetrate dense fabrics with ease, ensuring clean, precise stitches without snagging or tearing.

  • Additionally, using hand sewing machines can often lead to more durable and quality finishes. While mass-produced furniture may rely on automated processes that compromise craftsmanship, hand-sewn upholstery demonstrates a commitment to quality and artistry. Customers are increasingly drawn to pieces that reflect individuality and skill, making manual techniques more relevant than ever.
