shovel
Enable an AI agent to recognise a shovel, assess its suitability and condition for a particular material and task, and decide whether to use, maintain, repair or withdraw it.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a shovel, assess its suitability and condition for a particular material and task, and decide whether to use, maintain, repair or withdraw it.
A shovel is a manual or machine-mounted implement whose working element is a dished or slightly concave blade (the scoop) joined to a shaft, stick, or boom, designed primarily to penetrate, lift, and throw or dump bulk material rather than to cut a clean vertical face in undisturbed ground.
It can be Assess whether the shovel can penetrate or loosen the specified material within documented limitations.; Gather, lift, carry over a short distance and discharge loose material using a suitable shovel.; Push or scrape material where the head design and surface compatibility support that operation.; Inspect the blade, shaft, grip, connections and any adjustable locks before use.; Clean, maintain or replace supported components according to construction and available instructions.; Withdraw the shovel from a proposed task when damage, contamination or unresolved limitations prevent a supported use decision..
Distinguishing features
Look for a substantially continuous blade or scoop, connected to a manually controlled handle, that can gather and move loose material; separated working tines suggest a fork.
Inspect whether the head supports material during lifting and transfer, rather than functioning principally as the transverse scraping or chopping head of a hoe.
Record blade curvature, side rise, cutting edge and handle alignment when distinguishing a shovel from a spade; a seller's name alone does not settle this boundary.
Check whether the implement is a complete hand-operated tool or a working attachment that depends on a powered machine.
For snow tools, inspect whether the head and handle support lifting a retained load or primarily pushing material along a surface.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Shovel identity and boundaries Establish whether the item belongs to this entry and which shovel configuration it represents.
Similar names can refer to tools with different working heads and operating requirements.
Working tool recognition
Recognise the shovel through its assembled form and working action.
Blade and handle configuration
Record evidence of a material-gathering blade or scoop and a handle arranged for manual control.
- Does the assembled item have a continuous working head capable of gathering and supporting material during transfer? definition
- Is this a complete manually operated shovel, a replacement component or a machine attachment? boundary
Type and neighbouring tools
Separate supported type identification from ambiguous naming.
Type evidence
Record the declared type and the physical features supporting or complicating that designation.
- What markings, manufacturer information or other evidence identify its shovel type and intended material? provenance
- Which observed features distinguish it from a spade, scoop, snow pusher or trowel, and where does classification remain unresolved? boundary
Head and material engagement Describe how the working head enters, gathers, retains and releases material.
Shovel suitability depends on blade geometry and its interaction with the particular material and surface.
Entry and surface contact
Characterise the leading edge and features used to press the blade into material.
Edge and foot support
Record the entry profile, edge condition and any head features intended to accept foot pressure.
- What are the leading-edge profile, width and current wear or damage? measurement
- Does available evidence support applying foot pressure, and which part of the head is intended to receive it? action
Load retention and discharge
Characterise the head's usable carrying shape and release behaviour.
Scoop geometry
Record blade area, curvature, side rise and features that affect retention or discharge of the intended material.
- What are the head's length, width, depth and head-to-shaft angle, using stated measurement references? measurement
- For the proposed material, what evidence shows whether a gathered load remains on the head and releases without excessive sticking? action
Shaft, grip and control Describe how the user holds, positions and controls the loaded shovel.
A suitable head alone does not establish whether the complete shovel can be controlled in the intended space and task.
Reach and hand placement
Record handle geometry and available holding positions.
Usable handling geometry
Capture overall length, shaft shape, terminal grip and the condition of surfaces intended for holding.
- What are the overall length, shaft shape, grip type and usable hand positions? measurement

- Which cleaning, fastening, edge-maintenance or component-replacement actions are supported for this construction? action
Task fit and use decision Connect the shovel's observed configuration and condition to a proposed operation.
The agent needs a supported decision about a particular use, including cases where evidence is insufficient.
Material and operation fit
Assess the requested action against intended use and available limitations.
Supported shovelling operation
Record whether the evidence supports penetrating, gathering, lifting, pushing or scraping the specified material.
- What material, surface and operation are proposed, and which observed features or instructions support using this shovel for them? action
- What documented restrictions or ratings apply, and which proposed demands, such as prying or striking, remain unsupported? boundary
Readiness and withdrawal

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- United Kingdom and Ireland: trade and gardening usage keeps 'spade' (digging, relatively flat blade, often a tread) distinct from 'shovel' (moving loose material, dished blade). North American retail often sells digging tools as 'shovels'.
- United States and Canada: 'round-point' and 'square-point' are the hardware-aisle names; long-handled 'western' or irrigation shovels are a regional agricultural pattern.
- German-speaking Europe: Schaufel (dished shovel/scoop) versus Spaten (spade); snow tools are often Schneeschieber (pusher) rather than a lifting shovel.
- Military entrenching tools follow national patterns (US E-tool, German Klappspaten, etc.) rather than a single civilian hardware type.
- Snow-shovel use and municipal clearing duties are concentrated in snow climates; the same object is a seasonal specialty in temperate maritime regions.
- Which of these regional variation hold for the sense of shovel this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Spade - A spade has a flatter, thinner blade with a sharper cutting edge and usually a tread for the foot; it is made to cut and lever undisturbed soil. A shovel's blade is dished so it will hold a load for lifting and throwing. In British usage the names track that function; in North America many digging spades are sold as shovels.
- Snow pusher (snow sledge / Schneeschieber) - A pusher is a wide, often wheeled or long-bladed tool meant to slide snow aside without lifting it. A snow shovel has a shorter, dished blade and is used to lift and throw. Many consumer 'snow shovels' are hybrids; the test is whether the intended stroke is a lift.
- Scoop (open trough, no point) - A scoop is a deep trough, often with a rolled lip and no pointed tip, for grain, feed, or loose bulk. Overlaps the scoop-shovel kind; separate when there is no digging point and the tool is not intended to enter packed ground.
- Trowel - One-handed, short-hafted masonry or garden tool; a shovel is two-handed (or machine-mounted) and sized to move a bulk load, not a pointing or planting handful.
- Hoe or mattock - The blade is set across or offset from the handle for chopping, scraping, or picking, not in line with the shaft for lifting a scooped load.
- Fork / pitchfork / spading fork - Working end is tines, not a solid blade, so it will not hold fine bulk (sand, grain) the way a shovel will.
- Excavator bucket (general) - A general excavator or backhoe bucket may dig, cut, and grade; a face or power shovel is the machine sense of 'shovel', typically crowding into a face and dumping by racking or stick motion. Separate by machine kinematics and by whether the object is a replaceable bucket or a named shovel class.

What the second pass must settle
- Does registry policy include spades, hand scoops and snow pushers within shovel, or assign them to neighbouring entries?
- Which primary sources establish intended operations, restrictions and any load ratings for the shovel variants represented?
- Which inspection criteria reliably distinguish acceptable wear from defects requiring withdrawal for each head, shaft and connection construction?
- What repeatable assessment should be used for load retention and release across materials with different density, moisture and adhesion?
- Which specialist shovel features require additional coverage, and what evidence is needed to verify claims such as electrical insulation or spark resistance?
