# Remodelled Curved Hatchets The Vipukirves Axe by Heikki Karna Requires Less Force to Split Wood By Meghan Young | Published 2014-04-24 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/vipukirves-axe References: [ohgizmo](http://www.ohgizmo.com/2014/04/24/turns-possible-reinvent-axe/) & [vipukirves.fi](http://www.vipukirves.fi/english/index.htm) For those who thought the [hatchet](https://www.trendhunter.com/trends/hatchblade) was one tool that didn't require a remodelling, the Vipukirves Axe proves them wrong. It has replaced the conventional straight edge with a [curved one](https://www.trendhunter.com/trends/qrevo-curvx), showing that sometimes the most direct route is not necessarily the better one. The Vipukirves Axe resembles a rigid robot claw and does as much damage as one depicted in a sci-fi flick would do. Invented by Heikki Karna, who is based in Sipoo, Finland, the Vipukirves Axe splits wood more easily by offsetting the center of mass to the side, generating some rotational torque. Oh Gizmo writes, "This torque, applied to the part of the axe that’s already in the wood, acts as a [lever and splits the wood](https://www.trendhunter.com/trends/klhip) down its fibre, reducing the amount of force needed to accomplish the same results." ## Trend Insights (Trend Hunter) - Score: 5.0/10 - Popularity: 61% | Activity: 82% | Freshness: 8% - Audience gender: 90% men, 10% women - Primary generations: Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### Key Themes Behind This Trend - **Remodelled Hatchets:** The Vipukirves Axe has disrupted traditional hatchets by replacing the straight edge with a curved one and offsetting the center of mass to generate rotational torque for easier wood splitting. - **Curved Tool Design:** The Vipukirves Axe has shown the potential for curved tool designs to improve functionality and efficiency. - **Rotational Torque Technology:** The Vipukirves Axe has introduced the use of rotational torque technology in tool design for easier and more efficient wood splitting. ### Where This Applies - **Outdoor Tools:** The outdoor tools industry could benefit from the Vipukirves Axe's innovation in hatchet design to make their products more efficient and easier to use. - **Woodworking:** Woodworking industry professionals can use the Vipukirves Axe's innovation in hatchet design to improve wood splitting efficiency and reduce the physical strain on workers. - **Robotics:** The robotics industry could develop robotic arms mimicking the rotational torque technology used in the Vipukirves Axe for increased strength and functionality. ## Related on Trend Hunter - [Proficient Pack-Friendly Axes](https://www.trendhunter.com/trends/camp-axe.md) - [Multipurpose Camper Axes](https://www.trendhunter.com/trends/allinone-transforming-forest-axe.md) - [Snap-to-Unfold Axe Designs](https://www.trendhunter.com/trends/provoke-x.md) - [Axe-Style Pizza Cutters](https://www.trendhunter.com/trends/pizza-axe.md) - [Camper Multitool Axes](https://www.trendhunter.com/trends/zombinator-survival-hatchet.md) - [Modernized Campsite Axes](https://www.trendhunter.com/trends/gerber-bushcraft-axe.md) - [Adaptable EDC Axe Accessories](https://www.trendhunter.com/trends/crkt-provoke-x.md) - [Collaboration Campsite Axes](https://www.trendhunter.com/trends/prometheus-design-werx-spd-x-hardcore-hammers-axes.md) - [Collaboration Backcountry Hatchets](https://www.trendhunter.com/trends/adler-hatchet.md)
