Trace two legs through paper in a direction-labelled vector section, retaining hidden scope without real stapling or repair instructions.

Draw only a formed staple-through-paper section, without pressing, removal or handling sharp metal. State the section direction, then identify upper crown, two penetrating legs and underside bends. All lines are manual illustration; invented thickness and bends establish neither stapler capacity nor real binding safety.

## Declare section plane and paper layers

On a landscape canvas draw a paper-stack side section through the crown and both legs, explicitly labelled schematic section rather than overhead photograph. Use horizontal top/bottom boundaries; thickness 40 and crown span 240 are drawing proportions only. Two or three pale layer lines do not count actual sheets. Group sketch, paper, staple and notes, leaving room above/below for metal. Reduce plank-like darkness/depth. If it resembles an overhead U, establish paper side layers and direction instead of mixing viewpoints.

## Connect one crown to two legs

Place one crown over the stack, joining one downward leg at each end as a continuous piece. Inspect the centre path before adding narrow thickness; legs do not sprout independently from the crown middle. Span 240 measures leg positions, not stroke-expanded width. Keep penetrations fixed despite highlights. Reconnect three detached lines or thin an oversized handle-like crown. Before underside bends, verify one crown and two legs rather than two independent staples.

## Explain the segments within paper

This section through both legs may display metal within the paper thickness, but the legend must explain why; an ordinary opaque side photograph would not. Both legs run from top to bottom without stopping inside or crossing sideways to another penetration. Break paper-layer marks appropriately to avoid apparently severing metal. An optional exterior view must not show every hidden segment as visible solid line; label view identities separately. Without a reliable bend reference keep the simplified section and omit stapler mechanisms, channels and anvils.

## Return each underside bend to its leg

Choose an invented inward-bent underside state: left leg turns right and right leg turns left, both near the lower surface without returning through the top. Each bend continues from its own leg, not an unexplained central metal ball. A small centre gap aids legibility but is no standard dimension. For two rightward bends inspect an unreflected copy; for apparently severed paper reduce heavy borders while retaining layers. This selected state does not generalise bend direction or angle to every stapler and staple type.

## Differentiate metal from paper marks

Use mid-grey metal with narrow highlights, warm-white paper and pale layer lines, with an explicit material/section legend. Monochrome must retain a traceable metal path without silver-colour guessing. Upper-left light and contact shade aid distinction but establish no photographed surface finish. Give a printed-line-like crown modest depth/end connections; quiet paper marks resembling another staple. Leaders must remain distinct and not be counted as a third leg. Omit unverified page counts, product sizes and brands; dimensions remain canvas units.

## Make one disconnected-bend control

In a separate wrong copy detach only the left underside bend from its leg. Counts remain two legs/two bends, but the left path is discontinuous despite a familiar silhouette. Mark the precise gap, restore and trace crown-to-bend on the left, then inspect the untouched right side. Do not conceal the gap with shadow or join bends into a central crossbar. Edit vector objects only, without bending real metal or inferring injury from real failure. Retain the correct view and paper reference separately.

## Inspect paths before line finesse in output

Save and open a PNG, inspecting crown ends, upper penetrations, internal continuity and underside bends. Increase display size or local contrast for lost thin lines rather than thickening every paper edge. Keep section/direction labels readable to prevent an isolated image appearing operational. Hide unwanted tracing numbers while retaining the official legend. For covered internal segments in another format inspect object order and view convention rather than making paper transparent. Readability does not replace tracing; preserve editable source rather than overwriting it with a screenshot.

## Review view identity and both continuous paths

For a U-symbol appearance revisit section identity; for discontinuity inspect connections; for matching bend directions inspect reflection; for a third leg inspect leaders. Trace both sides after each repair rather than merely counting legs. Retain section direction, paper convention, one crown/two legs/two bends, detached control and output, explaining numbers and hidden segments. This stationary vector explanation includes no stapling, removal, loading or sharp-object test. It is neither a standard binding drawing nor a safety proof, and directs no pixel-based modification of real tools or staples.
