Product Name & Model

Product name: Pointed Triangle Trowel
Construction line: CO2 Welded Carbon Steel

Art. Nr (three blade sizes): 281621 (120 mm), 282621 (140 mm), 283621 (160 mm).

These three art numbers are one product family in one blade pattern. They differ only in blade size. Related products in the range include the Triangle Trowel (260604), Heart Trowel CO2 (263604) and Heart Trowel Spot Welded Stainless Steel (263304).

The tool has a flat delta (triangular) blade running to a single sharp point at the toe, a short cranked shank welded to the blade heel, and a soft-grip handle (BF21).

The second Pointed Triangle CO2 line: 892621 / 893621

Leading Tools carries a second line also titled "Pointed Triangle Trowel / CO2 Welded Carbon Steel", with art numbers 892621 (120 mm) and 893621 (140 mm) and a different blade shape (see the catalog). The sizes overlap 281621 (120 mm) and 282621 (140 mm).

Core Features

Delta blade running to a single sharp point

The blade is flat and triangular: widest at the heel where the shank foot is welded on, tapering in a straight line on both sides, and terminating in one sharp point at the toe. There is no rounded nose, no square toe and no notching. This is the geometric difference from the Triangle Trowel (260604) in the same range, whose blade is rounded. The point is the working feature, used for internal corners and fine detail.

Wide heel for mortar carry

The heel section is wide enough to hold a small working charge of mortar, so the operator is not reloading after every placement. The blade picks up the mortar and carries it to the edge of the joint; pressing and compacting it into the joint is done with a Tuck Pointing Trowel or a Brick Jointer.

Progressive taper: contact area falls as you approach the toe

Because the blade narrows continuously, the amount of steel in contact with the work reduces the further forward you go. The operator changes the effective width of the tool simply by changing where along the blade the material is worked, so one blade can be used for both fine detail and wider areas without swapping tools.

Carbon steel blade

The line designation states CO2 Welded Carbon Steel. Carbon steel blades cost less, but they must be wiped dry and thinly oiled after use, or they will rust.

CO2 welded blade-to-shank joint

The blade and the shank are separate components joined by CO2 welding; this is a fabricated assembly, not a one-piece forging. It is meant for light mortar handling, patching and detail work; do not use it to lever, pry, cut or strike.

Soft-grip handle (BF21)

The handle is the BF21 soft grip. Other handles can be fitted on request; contact Leading Tools sales.

Three metric sizes

120, 140 and 160 mm, approximately 4.7, 5.5 and 6.3 in.

Product Advantages

It does the job a bulk trowel cannot finish

The normal masonry sequence is bulk placement with a large trowel, then a smaller tool for detail work. The Pointed Triangle Trowel is that smaller tool: it picks up a small amount of mortar, patches and repairs small areas, and carries mortar to the edge of the joint. Pressing the mortar into the joint and compacting it is the job of a Tuck Pointing Trowel or a Brick Jointer.

Patching and small rebuilds without disturbing sound work

For patching, repairs and small rebuilds, a small amount of mortar can be picked up and placed precisely without loading the adjacent brick faces. Repointing itself, pressing mortar deep into a raked joint, is done with a Tuck Pointing Trowel or a Brick Jointer.

Corners, confined faces and decorative work

The triangular blade is the shape for corners and narrow faces, including detail rendering and repair work. The point can start a line of material directly in the vertex of a corner.

Complementary to, not interchangeable with, the margin trowel

The European Margin Trowel and this tool are often bought together and are frequently confused. The distinction is clear: the margin trowel's trapezoidal blade with a square toe is for filling corners, smoothing and patching, while this trowel's point is for precise placement of small amounts of mortar. The blade shapes are different, the applications overlap but they are not one tool.

How to Use

When to use

Basic technique

A. Patching and small rebuilds

Patching is the core application. The damaged area is cleaned back to sound material and dampened as the mix requires; a small amount of mortar is then picked up and placed with the trowel and smoothed to match the adjacent work.

The value of the pointed blade here is selective access: material goes only where it is needed without loading the brick faces around it. Repointing, pressing mortar deep into raked joints, is done with a Tuck Pointing Trowel or a Brick Jointer; this trowel carries the mortar to the edge of the joint.

For lime mortar work, work more slowly and clean the blade far more often. Mortar residue holds water against the steel, so a carbon steel blade used in lime needs cleaning and oiling more frequently than one used in cement mortar.

B. Corners, reveals and confined faces

The point lets a line of material be started in the vertex of an internal corner rather than worked in from the side. The delta face then distributes the material against the flanking surfaces. The triangular blade is the correct shape for corners and confined faces, including detail rendering and repair.

Choose the 120 mm (281621) where access is genuinely restricted: behind pipework, in deeply recessed joints, in ornamental stonework, because the smaller blade is easier to manoeuvre without fouling the surrounding surfaces.

C. Curved and arch work

The pointed toe can follow a tight radius without the toe dragging, and the taper means the operator changes effective width by changing where along the blade the material is worked. Hold the trowel at a shallow angle to the curved surface and let the two side edges of the delta ride on the adjacent masonry faces so they smooth those surfaces at the same time.

Handling notes

• Draw, do not push. The point is most effective drawn toward the operator; driving it forward into material risks the tip and gives less control.
• Keep the angle shallow (about 30°). Too steep an angle makes the point dig into the material.
• Respect the mortar load limit. The wide heel carries a working charge, but the blade is narrower overall than a Philadelphia or London brick trowel, so the load is less stable; reload more often rather than overfilling.
• Never lever or pry with the blade.
• Clean during the day, not only at the end of it. Mortar build-up at the blade-to-handle junction is what weakens it; several cleanings per working day are recommended.

FAQ

Q1. What is this tool actually for?
A: Picking up small amounts of mortar, patching and small rebuilds, repairs, detail rendering and plastering, and carrying mortar to the edge of the joint. It is also used for corners and confined faces.

It does not press and compact mortar into the joint: that is done with a Tuck Pointing Trowel or a Brick Jointer. It is not a bricklaying trowel; Philadelphia and London pattern blades exist for mortar pickup and bulk placement.

Q2. Which of the three sizes should I order?
A: 140 mm (282621) is the most versatile. Take 120 mm (281621) for restricted access and fine detail, and 160 mm (283621) for larger patches and larger curved work.

Q3. Carbon steel or stainless?
A: Carbon steel (this line) rusts if it is not dried and oiled after use; stainless has high corrosion resistance and needs less maintenance.

Buy this line for daily trade use by someone who maintains their tools, and the Spot Welded Stainless Steel sister line for occasional use, wet environments or lime mortar work. Use this tool for patching and detail work, never for levering, prying or striking.

Q4. How do I keep it clean and prevent rust, and why is mortar not releasing?
A: Clean and fully dry the blade after every use, apply a light protective oil before storage with particular attention to the point, and oil more often in damp conditions; clean several times per working day, because mortar accumulation weakens the junction between blade and handle.

If mortar does not release cleanly, the usual causes are oil, silicone or curing compound on the blade face, an over-plasticized mix, or a new blade that has not yet bedded in: wash it with detergent, work it through mortar for several passes and adjust the mix. If rust keeps recurring, switch to the stainless sister line.

Q5. When should I stop using it or replace it?
A: If the blade feels loose at the weld, stop using the tool; the weld cannot be reliably repaired in the field. If the point is bent or significantly deformed, replace the tool, because it compromises precise placement; a light burr can be dressed with a fine stone, but do not change the blade shape.

Specifications Overview

Blade geometry: the triangular pointed profile

In plan view the blade is a delta with three defining zones:

• Wide heel near the shank junction, provides the mortar-loading capacity, and is where the shank foot is welded.
• Continuous straight taper from heel to toe, the blade narrows progressively rather than in a step.
• A single sharp point at the toe, the critical geometric difference from the Triangle Trowel (260604) in the same range, whose blade is rounded.

Together those give a tool that is directional (the point can be aimed and driven into tight spaces), stable when loaded (the wide heel picks up and carries mortar), and progressively finer toward the tip (contact area falls as you work forward).

Comparison with related blade geometries in the Brick Trowel section

The Pointed Triangle Trowel occupies a specific niche: the triangular spreading face of the Triangle Trowel family combined with the pointed-toe precision of a brick trowel, in a narrower and more specialized form.

Construction: CO2 welding, carbon steel

This line is built as CO2 Welded Carbon Steel, the same fabrication route used across the Leading Tools Brick Trowel CO2 welded families.

What CO2 welding means in this context: the blade and the shank are separate components joined by CO2 welding.

Which of the three sizes

Size by application

Carbon steel (this line) or stainless

Practical guidance: if the tool goes into a van and comes out every day in the hands of someone who cleans and oils it, carbon steel is suitable. If it will be used intermittently, left in a damp bag, or used in lime mortar work, buy the stainless sister line instead.

CO2 welded or forged

This tool is for light work: picking up and placing small amounts of mortar for patching and detail work. Do not use it to lever, pry, cut or strike.

Care & Maintenance

Cleaning after use

• Remove material while it is fresh. Rinse the blade with clean water immediately after use. Carbon steel corrodes if cement or lime-based material is left to cure on the surface.
• Clean repeatedly through the working day. Mortar accumulation weakens the junction between blade and handle and can eventually lead to failure there, which is why several cleanings per day are recommended rather than one at the end.
• For partially hardened material, soak the blade in water to soften the residue, then use a wooden or plastic scraper. Do not use metal tools or abrasive pads on the blade face: they damage the finish and can affect the blade geometry.
• Dry thoroughly. Wipe the blade dry with a clean cloth after washing. Carbon steel must be stored completely dry.

Corrosion prevention: this is a carbon steel blade

A carbon steel trowel blade will rust if it is not dried and oiled, and it needs more frequent maintenance than a stainless one.

• Oil after cleaning and drying. Apply a light coat of machine oil or a dedicated tool oil to the blade, paying particular attention to the point. In damp environments, oil after every use. Wipe off excess before the next use so it does not contaminate the work.
• Store dry. Do not leave the trowel outdoors, in a damp tool bag, or near open buckets of water or mixed mortar.
• Lime mortar needs extra care. Mortar residue holds water against the steel; clean and oil particularly thoroughly after lime work.
• If the work is routinely wet or lime-based, the stainless sister line is the better purchase: that is the maintenance trade-off.

Handle maintenance: soft grip

The moulded soft-grip handle needs very little maintenance:

• Clean the grip with mild soap and water. Do not use solvents.
• Check that the grip is not torn or peeling.
• Check that the handle does not move on the shank; a handle that has developed play should take the tool out of service.
• Do not leave the handle standing in water or solvent.

Blade and point care

• Protect the point. The sharp toe is the most vulnerable part of the tool; avoid dropping the trowel on its toe, which deforms or dulls the point.
• Do not use the toe as a scraper or pry bar. Beyond blunting the point, prying can damage the tool.
• Inspect the point periodically. Hold the blade up to a light and check that the toe still comes to a clean point; a rounded toe substantially reduces the tool's precision capability.
• Check blade flatness. Lay the blade against a straightedge; a warped blade will not spread material evenly.
• Dress a light burr on the point or edge with a fine stone if needed; do not change the blade shape.

Weld joint inspection

The blade and shank are joined by a weld, so the joint deserves specific periodic attention. Do not lever or strike with the blade.

Check for hairline cracks, separation, or corrosion concentrated at the joint. A trowel with a suspected weld failure should be taken out of service immediately; the joint cannot be reliably repaired in the field.

Periodic inspection checklist

• [ ] Blade-to-shank weld area: cracks, separation, corrosion at the joint
• [ ] Point profile: still a clean sharp point
• [ ] Blade faces and edges: rust pitting
• [ ] Blade flatness against a straightedge
• [ ] Grip condition: tears or peeling
• [ ] Handle-to-shank fit: any developed play
