A 6 mm (0.24 in) tip on a stated 43 mm (1.69 in) reach, so it marks through a hole or into a recess
Seven leads supplied, with an integrated sharpener and a clip
A narrow lead breaks more readily than a carpenter pencil's
Best for: Marking through an existing hole — the job a flat pencil physically cannot reach.
A different geometry, for a job the flat pencil cannot do.
What the manufacturer publishes
An innovative marking pencil with particularly strong leads for home and trade use, for wood, metal, tile and concrete. Recommended as a construction pencil and deep-hole marker in bright orange, with a tip 6 mm (0.24 in) thin and 43 mm (1.69 in) long. A sharpener integrated into the pencil and a clip for attachment. Seven leads supplied.
The measurement that only this can take
Marking through a fixing hole is the commonest transfer in fitting work — brackets, hinges, rails, back plates. Every alternative is worse: marking around the outside and estimating the center, or holding the item and drilling through it and hoping.
A 6 mm (0.24 in) tip on a 43 mm (1.69 in) reach goes through the hole and touches the wall. That is the entire product.
The trade against a carpenter pencil
Thin leads snap. That is why seven come in the box, and why the flat pencil is still the right tool for everything that does not require reaching.
Availability
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

What gets asked here
What is a deep-hole marker for?
Transferring a position through something. Hold a bracket against a wall, put the marker through its fixing hole, and mark the wall behind it. A flat pencil is too wide to enter the hole and too short to reach the wall.
Does it mark on tile and metal?
THORVALD states wood, metal, tile and concrete. Special leads exist for hard, smooth surfaces where ordinary graphite skates.
Why seven leads?
Because a narrow lead in a hard material breaks. Refills are the consumable, and a marker without spares is a marker with one use left.
The only marker here whose holster has a drain hole — and the only one that stops both halves rolling away.
Body and fittings
A ROLL STOP on BOTH the pencil and the holster, stated. Every other marker on this shelf that addresses rolling addresses only the pencil — and a holster left on a sloping surface rolls away with the sharpener inside it, which is the half nobody else thinks about
Also stated
A HOLE IN THE BOTTOM OF THE HOLSTER, stated to lead dirt and moisture away from the pen for longer durability. Nobody else on this shelf publishes drainage, and a closed holster on a wet day is a tube of water around a lead: it is the mechanism by which a holstered marker rots rather than wears
Functions
A sharp and accessible sharpener placed in the HOLSTER, stated, and Hultafors adds the reason: the marker is easy to remove from its holster so you do not have to let go of what you are working with. The sharpener staying behind is the point — one hand keeps hold of the work
Supplied
The dispenser is stated to double as a BLADE SNAPPER and to fit the handle of Hultafors SRP knives. A second function nobody else on this shelf has, and a real one: snapping a blunt snap-off blade without pliers is a daily job
Material
A grip-friendly ergonomic design, stated, and easy lead changes. No barrel material, no lead diameter, no lead color and no HARDNESS is published — fewer figures than any other marker here
Stated dimension or range
Not published. No tip diameter, no tip length and no lead count appears, and the shape of the holster is stated to keep the pen in place when you move

A roll stop on the holster as well as the pencil
A drain hole in the holster base, unique here
No lead diameter, so a refill is a guess
Best for: Wet and dusty work, where a holster normally turns into a reservoir
A triangular body does what a flat pencil does — it stays on the beam — and the ten leads come in a case.
Body and fittings
A TRIANGULAR-shaped barrel, stated to prevent the tool rolling away. This shelf's introduction says a flat carpenter pencil does not roll off a beam and that this is one of its two virtues; a triangle keeps that property in a mechanical body, which a round barrel does not. It is one of two anti-roll designs on this shelf
Supplied
A TEN-PACK of assorted color replacement leads in a carrying case — Klein cat. no. 86503 — alongside the marking tool itself, cat. no. 86501. Ten is the largest lead count on this shelf, where the others ship four, six or seven, and a case rather than a loose sleeve is what stops 2.8 mm (0.11 in) leads snapping in a bag
Functions
A 2.8 mm (0.11 in) lead, stated to create long-lasting marks, with a built-in sharpener to keep it sharp for precision marking. Two point eight millimeters is the common mechanical carpenter lead and one of two diameters published on this shelf
Also stated
Tough enough for OSB, wood, concrete and metal, stated. OSB is the useful one on that list: a chipped, resinous, uneven face is where a soft lead skates and a hard one gouges, and it is the surface a framing pencil actually meets
Material
Not published. No barrel material, no tip dimensions and no lead HARDNESS appears — and the leads are described only as assorted color, with not one color named. This shelf's introduction says graphite disappears on dark stone where white or red shows; this listing gives you ten leads and no way to know which is which before opening the case
Reference and mounting
Two Klein catalog numbers inside one product reference: the 80189 kit is the 86501 marking tool plus the 86503 lead pack. No belt clip is stated, where two markers on this shelf publish one

The only actual line on a shelf called mason lines and plumb bobs — braided, orange, two hundred and fifty feet.
Stated dimension or range
250 FEET per reel, three reels. Every other product on this shelf carries between 10 and 14.5 feet of cord and six of the seven are bobs — so this is the only line on the shelf in any meaningful sense, and it carries seventeen times the length of the longest bob cord here
Material
BRAIDED, stated in the title, and ORANGE. Both are the things this shelf's introduction asks for: braided line resists the stretch that makes a twisted line sag differently at each setting, and bright colors stay visible against rubble. A twisted line also unwinds under tension and rolls a brick course off true as it does
Body and fittings
A line reel handle of durable polyethylene, stated, with the line securing in a convenient notch. It is a hand reel rather than a retracting one — the notch is what stops the line unwinding in a bag, and it is the whole mechanism
Supplied
Three reels at eight dollars seventy-nine — about two dollars ninety a reel of 250 ft. Three is the right number for a trade that loses line: one on the job, one in the van, one cut short and still useful
Also stated
TWO bullet points, and that is the whole listing. No breaking strain, no diameter, no material beyond braided, and no stretch figure — this shelf's introduction compares line STRENGTH and STRETCH, and neither appears
Functions
Not published: no twine size, no number, no weight. Mason's line is normally specified by a number — a #18 or #21 — which sets its diameter and breaking strain, and this listing gives none

250 feet, where every bob here carries ten to fifteen
Braided, which the hub intro says resists stretch
Two bullet points, and that is the whole listing
Best for: Setting out brickwork, fencing or a long datum, where a bob's ten feet of cord is nothing
The heaviest bob here, and the only one with bumpers to stop it marking the wall it hangs against.
Stated dimension or range
21 oz / 600 g — the heaviest bob on this shelf, where the lightest is 5 oz: a factor of four. This shelf's introduction says weight sets how quickly a bob settles and how little it swings in a draft, which makes this the bob for an open site, a stairwell or a long drop
Measuring mode
Quick-stabilizing: stops wobble AND SPIN within 6 seconds, stated. The same figure as the maker's 10-ounce bob on this shelf, which is the interesting part — doubling the weight does not halve the time, because the design rather than the mass is doing the work. Spin is the half nobody else mentions: a bob that has stopped swinging can still be rotating, and a rotating bob with an off-center tip traces a circle
Body and fittings
EMBEDDED SIDE BUMPERS, stated to protect both the bob and the work surfaces. Nobody else on this shelf has them, and they solve a real problem twice: a 600 g (21.2 oz) steel bob swinging into a finished wall marks it, and the same impact chips the bob's own plating
Functions
A thick ELASTOMER TIP GUARD, stated to keep the tip safe and secure. The tip is what a bob dies of — one drop rolls the point over — and a guard is the other answer to that problem; the brass kit on this shelf answers it with four spare tips instead
Material
Chrome plated to resist rust and corrosion, stated. Chrome is harder than nickel and resists the chip that starts the rust — which matters more on a 600 g (21.2 oz) bob, because a heavier bob hits harder when it is dropped
Supplied
A snap ring as standard, to connect and disconnect from a plumb line, stated. A snap ring rather than a knot means the same bob moves between a short line and a long one in seconds. NO LINE IS SUPPLIED — this is a bob, not a kit, and the shelf carries 250 ft of braided mason's line for under nine dollars

Twenty-one ounces: the steadiest bob on this shelf
Six seconds, and it stops SPIN as well as swing
No line supplied at all
Best for: A long drop outdoors or in a draft, where a light bob never stops swinging
The only bob here that says how long it takes to stop — and the only one you can hammer into a ceiling.
Measuring mode
Quick-stabilizing: the 10-ounce bob steadies WITHIN 6 SECONDS, stated. It is the only settling time published on this shelf. This shelf's introduction says weight sets how quickly a bob settles and the buying tip says to let it stop on its own rather than steadying it by hand — a published six seconds is what makes that instruction bearable, because the alternative is standing there not knowing whether to wait longer
Reference and mounting
THREE fixings in one head, stated: a setting pin for wood and drywall, a strong magnet for steel surfaces, and a hook for nails or studs. No other bob on this shelf offers more than two, and most offer none at all — a bare bob is tied to a nail somebody else put in
Functions
An AUTO-RETRACTING PIN STRIKER, stated for use with a hammer for overhead setting. That is the unusual one: you hold the setter against a ceiling and strike it, the pin drives in, and the striker retracts out of the way — so a plumb line can be dropped from a ceiling without first fitting a nail with a free hand you do not have
Stated dimension or range
10 oz / 300 g, published in both units, with a 14.5 ft self-retracting line. Ten ounces is the middle of this shelf, which runs from 5 oz to 21 oz
Body and fittings
A self-retracting line, stated for quick easy storage. Two bobs on this shelf retract; the rest use a hand reel, a card or nothing. The line construction is not stated — four listings on this shelf state braided, and this is not one of them
Also stated
Commercial grade for long-lasting durability, and described in the maker's own text as a compact and light-duty version. No tip material, no tip guard and no replaceable tip is published
