Vintage COES Knife Handle Monkey Wrench
8-Inch Wood, Worcester Mass. Tool

Vintage COES knife-handle monkey wrench with original wood handle, clear Worcester, Mass. maker’s marks, and smooth adjusting action. Lightly cleaned, oiled, and waxed, with stabilized age cracks in the handle and honest wear consistent with age and use.
Detailed description
A compact COES knife-handle monkey wrench with original wood handle and clear markings on both sides: “COES WRENCH CO. WORCESTER MASS.” on one side and “L. COES PATD DEC. 15, 1891 APR. 22, 1895” on the other. This is the classic smooth-jaw adjustable monkey wrench form, and the wood-handle “knife handle” construction is consistent with late-19th-century Coes wrench patents and trademark use. 
This wrench measures just over 8 inches long. The adjusting mechanism moves smoothly end to end. The jaws do not close 100%, which appears to be age/use wear rather than damage. The original wood handle remains in place and shows lateral age cracks on both sides that were stabilized; the handle is not loose. The metal retains aged patina, tool marks, and surface wear rather than a polished-over finish.
Restoration on this example was intentionally conservative: light cleanup only, followed by oil and wax, with handle crack stabilization to keep the original grip serviceable and presentable. No heavy buffing or over-restoration was done.
Good fit for:
- vintage tool collection
- shop or office decor
- machinist or mechanic gift
- light display or occasional light-duty use
A printed care sheet will be included with the wrench.
