A gorgeous boxed set of specialized precision wood scrapers. Because this is in such good condition and looks to be unused, I have attempted no cleaning and left any sort of restoration up to the buyer. Since I don’t know a whole lot about this set, feel free to contact me any comments or questions.
I had a hard time finding information about this set, so I turned to Apple’s AI search with the following query:
I'm looking for information on a bent neck wood scraper set by Hagen Engineering located at 5211 S. Monitor Ave., Chicago 1950s [one photo included]
The response:
What a beautifully preserved set. This photograph provides a wealth of context about your Hagen Engineering Bent Neck Wood Scraper Set.
Breakdown of the Set Components
Based on the custom fitted wooden box, this is a highly specialized multi-blade precision scraping kit:
The Main Scraper Handle: Features a contoured turned wood handle with a brass ferrule. The solid metal shaft has a distinct 90-degree bent neck, explicitly stamped with the Hagen name and "PAT. PEND." (Patent Pending). This design is highly functional; it lowers the center of gravity, protects the user's knuckles, and provides precise downward pressure directly over the cutting edge.
Interchangeable Profile Blades: The set contains at least 7 separate, specialized miniature scraping heads. Rather than standard flat card scrapers, these are configured for detailing, restoration, and pattern-making:
Convex/Concave Blades: Small curved steel elements designed to scrape inside coves, round-overs, or specific moldings.
Contour Scrapers: Specialized profiles meant to clean up intricate channels or fine cabinetry details.
Large Circular Blades: The wide, disc-like scraper tips (bottom row, second from right, and the one already mounted on the handle) are highly unique and used for scraping broader, smooth recessions or specific hollows.
The Locking Screw & Post Fitting: The center of the box features a standard slotted machine screw. The blades drop onto the post at the end of the bent neck and lock tight, ensuring zero wiggle while under heavy pressure.
The Abrasive Stone: The dark rectangular block on the right is a small honing or dressing stone, used to continually apex the tiny steel scraper profiles to keep them throwing clean wood curls.
Historical and Design Nuances
The paper label inside the lid features a classic art-deco/mid-century emblem reading:
"Hagen Engineering • 5211 S. Monitor Ave. • Chicago 38"
The use of "Chicago 38" is a critical chronological clue. This is a pre-ZIP code postal district (or zone number). The U.S. Post Office introduced these two-digit zone codes in 1943, and they were completely replaced by the modern 5-digit ZIP code system in 1963. The "Chicago 38" designation confirms this tool kit was manufactured between 1943 and 1963, aligning perfectly with your 1950s timeline.
Today, the factory site at 5211 S. Monitor Ave (located in Chicago's Garfield Ridge neighborhood near Midway Airport) has since been redeveloped into residential property. Mid-century operations like Hagen Engineering were typical of Chicago's booming post-war machinist and tool-and-die trade, which frequently produced limited-run specialty trade tools that are now highly prized for their craftsmanship and rarity.
