Workshop tools and woodworking terminology Identify the statement that is incorrect regarding common hand tools used in fitting and carpentry.

Introduction / Context:
In basic workshop practice, clear understanding of hand-tool names and functions prevents selection errors, improves quality, and increases safety. This question checks your ability to distinguish among layout tools, chisels, and boring tools used in carpentry and fitting.

Given Data / Assumptions:

• Mortise gauge is a standard marking-out instrument.
• Gouges are a family of chisels with curved or hollow cutting edges.
• Auger is a traditional woodworking boring tool used with a brace or as a hand auger.

Concept / Approach:
We compare each statement with accepted definitions from woodworking and metalworking practice. The goal is to identify the one that contradicts standard tool functions. Marking gauges, chisels, and boring tools all have distinct purposes and geometries.

Step-by-Step Solution:
Mortise gauge: has two scribing pins adjustable to mark parallel lines for mortise-and-tenon joints, so this statement is correct.Gouges: are chisels with a concave or hollow blade profile for scooping and shaping curves, so this statement is also correct.Auger: is not a planing tool. It is a boring tool designed to drill holes in wood, typically featuring a screw point and spiral flutes for chip removal. Therefore the statement calling it a planing tool is incorrect.

Verification / Alternative check:
Consult any standard carpentry handbook: planing tools (e.g., jack plane, smoothing plane) shave surfaces; boring tools (e.g., auger, bradawl, gimlet) create holes. The functions do not overlap.

Why Other Options Are Wrong:
'The mortise gauge has two scribing pins.' — Correct; two pins set the mortise width.
'The gouges are chisels with a hollow-shaped blade.' — Correct; the curved edge defines a gouge.
'All of these statements are correct.' — Incorrect because the auger statement is wrong.
'None of these statements is correct.' — Incorrect; two statements are clearly correct.

Common Pitfalls:
Confusing boring tools with planing tools due to similar handles; assuming all chisels are flat-edged; overlooking that marking gauges can have one or two pins depending on type (single-pin marking gauge vs. two-pin mortise gauge).

Final Answer:
An auger is a planing tool.
