# Deadly Mail Slicers Sever Envelopes with the Cas Hanwei 1918 Mark 1 Letter Opener By Matt Ho | Published 2011-08-21 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/cas-hanwei-1918-mark-1-letter-opener References: [budk](http://budk.com/Gifts-and-Gadgets/Cas-Hanwei-1918-Mark-1-Letter-Opener) & [budk](http://budk.com/Gifts-and-Gadgets/Cas-Hanwei-1918-Mark-1-Letter-Opener) When it comes to tools for slicing open that mail, it really doesn't get any deadlier than the Cas Hanwei 1918 Mark 1 Letter Opener. For a bit of background, the 1918 Mark 1 was actually designed for close combat during World War I, but was only used during World War II. Now this vintage piece has been given a less violent purpose in the form of the Cas Hanwei 1918 Mark 1 Letter Opener. The [blade is made from steel](https://www.trendhunter.com/trends/victorinox-knives) and is definitely more than sharp enough for its users. Below that is a hilt and a [blackened bronze grip](https://www.trendhunter.com/trends/wesn-scrimshaw-henry-collection) in the shape of a brass knuckle. The Cas Hanwei 1918 Mark 1 Letter Opener will probably be the most badass mail slicer anyone will ever come across. Just make sure you use it specifically for letters. ## Trend Insights (Trend Hunter) - Score: 0.5/10 - Popularity: 2% | Activity: 5% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### What's Driving This Trend - **Vintage-inspired Office Tools:** Opportunities for creating unique and stylish office tools that incorporate vintage designs and repurpose historical items. - **Multi-functional Letter Openers:** There is a potential market for letter openers that serve dual purposes, combining their functional use with a unique twist or added feature like a grip or decorative hilt. - **Novelty Office Accessories:** The demand for unconventional and eye-catching office accessories presents an opportunity to design and produce unique letter openers that add flair and personality to the workspace. ### Who This Affects Most - **Office Supplies:** The office supplies industry can explore innovative designs and concepts for letter openers that cater to the growing demand for aesthetically pleasing and functional office tools. - **Gifts and Novelty Items:** Gift and novelty retailers can capitalize on the trend of unique office accessories by offering creative letter openers as quirky and practical gift options. - **Collectibles and Antiques:** Collectible and antique dealers can tap into the market of vintage-inspired office tools, including repurposed items, such as the Cas Hanwei 1918 Mark 1 Letter Opener, which appeal to collectors and history enthusiasts. ## Related on Trend Hunter - [3D-Printed Paper Knives](https://www.trendhunter.com/trends/paper-knives.md) - [Minimalist EDC Dagger Designs](https://www.trendhunter.com/trends/copper-sheath-dagger.md) - [Multifunctional EDC Scalpels](https://www.trendhunter.com/trends/precision-scalpel-set.md) - [Sensibly Sharp Elevated Knives](https://www.trendhunter.com/trends/new-task-knife.md) - [Coin-Style Disc Shaped Cutters](https://www.trendhunter.com/trends/quarter-ccutter.md) - [Miniature EDC Sword Designs](https://www.trendhunter.com/trends/micro-katana.md) - [Dynamic Movement Pocket Knives](https://www.trendhunter.com/trends/craighill-sidewinder-knife.md) - [Tactical Tool-Packed Pens](https://www.trendhunter.com/trends/tekto-tak-pen.md) - [Ultra-Compact Outdoor Knives](https://www.trendhunter.com/trends/slidewinder.md)
