Machinist Try Square Value Guide

This American-made machinist try square represents the pinnacle of early 20th-century precision, blending a durable steel blade with a classic brass-bound wooden stock. These tools are highly collectible because they represent the transition from traditional craftsmanship to industrial-era accuracy, often featuring decorative brass inlays that signify premium quality.

What affects the value of Machinist Try Square?

• The presence of decorative brass inlay, which indicates a higher-tier tool intended for professional tradesmen.
• The overall condition of the steel blade, specifically the absence of deep pitting or heavy oxidation.
• The tightness of the joinery between the blade and stock; any 'play' or movement significantly reduces the tool's utility and value.
• The preservation of the original wood finish and the clarity of any stamped maker's marks.

How to Identify Machinist Try Square?

• Check for the characteristic brass binding along the inner edge of the wooden stock, which protected the wood from wear.
• Look for manufacturer stamps on the steel blade or the wooden handle, common for US makers between 1900 and 1950.
• Verify the presence of three or more brass rivets securing the steel blade to the wooden stock for structural integrity.
• Inspect the wood for the dark, dense grain typical of rosewood or mahogany used in high-end tools of this era.
