Sar Jane: The Adjustable Hammer

Revolutionizing the Way We Use Hammers

Introducing Sar Jane, the innovative hammer designed by Nan Wang that is set to transform the way we approach our DIY projects and daily tasks.

Traditionally, hammers come in fixed weights, requiring us to own multiple hammers for different purposes. However, Sar Jane challenges this norm by offering a single hammer that can be adjusted to meet various needs.

One of the standout features of Sar Jane is its adjustable weight system. By adding heavy metals to the handle, users can precisely control the weight of the hammerhead. When delicate precision is required, the weight can be reduced by locking the slider on the handle, making it effortless to operate. On the other hand, when maximum impact force is needed, the metal slider can be transferred from the handle to the hammerhead, increasing the overall impact force without changing the total weight. This ingenious design allows Sar Jane to adapt to a wide range of situations, eliminating the need for multiple hammers.

Not only does Sar Jane revolutionize the functionality of hammers, but it also addresses environmental concerns. Most hammers are made of alloy steel, which involves a complex production process that consumes significant energy and releases substantial carbon emissions. However, with Sar Jane, there is no longer a need to own multiple hammers for different purposes, reducing resource consumption and carbon emissions. By choosing Sar Jane, users contribute to a more sustainable society.

Measuring at a length of 310mm, with a hammer handle length of 280mm and a width of 40mm, Sar Jane is designed to provide optimal comfort and control. The hammerhead measures 110mm in length and 25mm in width, ensuring precise and efficient strikes. Crafted from 95% alloy steel, Sar Jane guarantees durability and longevity.

Operating Sar Jane is a breeze. When the weight of the hammer needs to be increased, simply turn the slider counterclockwise to unlock it. Slide the unlocked slider from the bottom to the top to adjust the weight. Once the desired weight is set, turn the slider clockwise to lock it in place. Now, you are ready to tackle any task, from driving nails into place to smashing walnuts.

Sar Jane has already garnered recognition in the design world. In 2021, it was awarded the prestigious Iron A' Design Award in the Prosumer Products, Tools, and Machinery Design category. This accolade is a testament to Sar Jane's well-designed, practical, and innovative nature, meeting professional and industrial requirements. The adjustable hammer is respected for its integration of industry best practices and competent technical characteristics, providing fulfillment and positive feelings to users while contributing to a better world.

With Sar Jane, Nan Wang has revolutionized the way we use hammers. This adjustable hammer not only offers versatility and convenience but also promotes sustainability. Say goodbye to cluttered toolboxes and embrace the future of hammering with Sar Jane.
