Ketch-All Multiple Catch Mousetrap Value Guide

The Ketch-All Multiple Catch Mousetrap is a landmark of American ingenuity, originally invented by Austin Enos Kness in 1924 using a simple tobacco tin. These vintage galvanized steel units are highly collectible because they represent the first 'automatic' live-catch technology that could capture multiple rodents without a manual reset.

What Is Ketch-All Multiple Catch Mousetrap Worth?

The typical price range for Ketch-All Multiple Catch Mousetrap is $45 - $50 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Mechanical functionality: A working wind-up spring and rotating paddle significantly increase the value.
• Surface condition: Examples with minimal rust, original paint, and clear legible stamping command prices near $50.
• Completeness: The presence of the original internal components and the winding key is essential for top-tier pricing.
• Age markers: Earlier models from the 1940s with specific patent dates are more desirable than modern iterations.

How to Identify Ketch-All Multiple Catch Mousetrap?

• Look for the distinct wind-up knob on the side used to power the internal paddle wheel mechanism.
• Check for the Kness Mfg. Co. stamping and the Albia, Iowa origin mark on the metal housing.
• Verify the material is authentic galvanized steel or tin, typical of the 1940-1960 production era.
• Inspect the clear or solid metal top for the original patent information and 'Ketch-All' branding.

History of Ketch-All Multiple Catch Mousetrap

Patented in 1924 by Austin Enos Kness, this 'automatic' trap revolutionized pest control by capturing multiple mice without needing to be reset after each catch. Kness originally built the first model out of a tobacco tin to protect his schoolhouse from rodents, eventually founding the Kness Mfg. Co. which still produces these traps today.
