About   Lindström

     Lindstrom 从1856年开始就致力于研发和生产高精度钳子,是世界上最早开始生产手动工具的厂家之一。以高精度工具见长,提供包括高精度的螺丝刀、镊子、扭力工具等系列产品。在电子、珠宝行业享有盛誉,通过专利研发、满足市场需求和保持技术领先。


     Lindström has developed and produced high-precision cutters and pliers since 1856 - making us the oldest continuous producer of handtools in existence today.

     Lindström is now a separate business unit within SNA Europe. Lindström is responsible for developing, producing and marketing not only cutters and pliers, but an assortment of high-precision tools including screwdrivers, tweezers, torque drivers and more. We have maintained our competitive edge through technical understanding, response to market needs, and commitment to advanced technology.

     Some competitors have been able to implement one facet or another of the Lindström manufacturing process. Others have tried to copy the form, appearance and even the actual part numbers of Lindström tools. However, none has been able to successfully blend all the elements required to achieve the level of performance recognized as a true Lindström tool.

     Our customers today have applications more demanding, varied and difficult to solve than ever before. They demand better performance, longer life and lower costs in every area. People have come to expect only the best from us. And as usual, Lindström will deliver.

      Many years ago, cutters were primarily used in heavy-duty work, i.e. cutting heavy electrical wire and wires used in the telecom field. In order to meet the requirements of linesmen and other general use workers, tool manufacturers designed a cutter that left a wide, pyramid-shaped lead end after cutting. Its hardness was adequate for the strain put on the cutter blades.
      However, as the electronics and other related industries developed, the requirements on tools, and in particular cutters, became far different. For example, many people believe that an electrician must do a lot of cutting. Yet, an electrician may make fewer cuts in his lifetime than some electronic assembly workers make in one month! Therefore, the need for cutting small wires thousands and thousands of times necessitated a radically new and innovative technology.
Small cutters were needed that could cut both extremely small and relatively large diameter wires, often of quite different materials. In addition, the lead ends had to be quite different since the solderability of these wires was of paramount importance. These lead ends had to be covered completely and properly with no bare copper or basis material exposed.
      Compounding the problem was the accessibility issue, as not all cutters could get into the same area. Transmission of the mechanical shock of cutting to sensitive  semiconductor components added even more cutter design challenges. However, despite some manufacturers’ claims to the contrary, there are no secret or ‘magic’ materials or processes that can give you some kind of super cutter for all applications Some inherent trade-offs in the design of tools and choices must be made in order to meet certain application requirements. For example:
      At what point is the cutter head small enough to gain access and still be able to withstand the impact of cutting wires (of various sizes) innumerable times?
How flush should the cutting edges be in order to meet tough specifications yet still keep tool life extended to the maximum? And what about resist- ance to edge damage due to occasional misuse?
      To what degree of hardness should the tool be made in order to extend tool life and still limit breakage due to being too brittle?
What type of joint should be put into a tool to extend the precision of the cutting edges and still be cost effective for you to use?
      Understanding these trade-offs is the key to making an objective and cost-effective choice of tools for your specific application.

      Lindström cutters offer an unequalled blend of the technical elements required to achieve the level of performance demanded by a growing number of users.

Every cutter begins with the fundamental materials. Even slight adjustments to these ingredients can change the way steel performs. Lindström has been refining this formula for over 150 years. The 1% carbon, with a pinch of chrome and other keymaterials, is similar in many ways to the steel used for high-quality ball bearings. This is the material used for all Lindström pliers. The use of ball-bearing grade steel and appropriate heat treatment ensures Lindström cutters last for longer than other brands used in the same applications.

One of the challenges in tool design and usage alike is the search to increase tool life. Decreased life is caused generally by usage beyond the limits of the material and its corresponding hardness.
The use of ball bearing grade steel together with proper heat treatment offers the possibility of a cutterof tremendous resiliency and toughness with the ability to withstand greater impact, yet with the ability to return to its original form without damage. This is one of the reasons why Lindström cutters offer greater life and have less breakage than other brands used in the same applications.

Another characteristic that emerges from a Lindström cutter is the ease with which the tool makes its cut. The precision of the machining makes it as if there is a built-in, which makes the cutting easier. This not only helps to make a better cutter, but also reduces operator fatigue.
Different steels have different personalities – each allowing a certain level of hardness. If specific steel is hardened too much for its composition, it will break easily. On the other hand, not enough hardening can sharply reduce tool life. 
How steel is cooled after hardening and recognizing the different strength capacities of that steel are some of the key factors that make the hardening process a difficult science to master.
Measuring the hardness on a Rockwell Hardness Scale, Lindström cutters are elevated to a hardness of 63-65 on the cutting edge. This hardness ranks among the highest of any cutters made. For most manufacturers, this hardness level would create a high breakage rate.
Yet, because of the steel, and proper control and consistency of the hardening area – even when used beyond the rated capacity – Lindström cutters have remarkably little breakage.
