The most permanent marking crayon in this catalog, and it is meant to be.
What the manufacturer publishes
Forestry and signing crayons in a hexagonal form, 12 × 120 mm (0.47 × 4.72 in), in green. Oil-based, paper-sleeved. Made from the best raw materials with an extremely high pigment loading.
Why forestry grade exists
A log marked in spring may not be cut until autumn. In between it sits outside in rain, snow and sun, is moved by machine and is stacked against other logs. Chalk is gone in a week and wax fades; an oil-based, heavily pigmented crayon is still legible at the end.
Which means it is the wrong crayon for a wall
Everything that makes it right for a log stack makes it wrong indoors. If the mark is going to be seen afterwards, the temporary chalks and the pencils in this catalog are the tools; this one is for marks that must not disappear.
Availability
No such listing: the American Amazon shop answers the reference with a search box rather than a page.
Read from Keepa on the day this page was last revised; stock and price both move without notice.
What gets asked here
Why green rather than red?
Contrast. On brown bark and sawn timber, green and blue read further than red, which sinks into the color of the wood. Forestry conventions also use color to carry meaning, which is why these come in several.
What does oil-based change?
Weather resistance. A wax or chalk mark on a log stack fades over a season; an oil-based one is still there when the timber is finally cut.
Can I use it indoors?
You can, and you will not get it off. This is the most permanent of the three marking chalks in this hub.
Two ounces of chalk at twenty dollars, with neither the color nor the grade published — the two things this shelf says decide everything.
Also stated
NO Color and NO GRADE. This shelf's introduction opens on it: chalk comes in two grades and choosing wrongly is not recoverable — temporary brushes off, permanent survives weather and also survives being wrong on a finished wall. This listing states neither, and the buying tip says the color is what normally tells you
Stated dimension or range
Two bottles of one ounce each, at twenty dollars thirty-seven — about ten dollars nineteen an ounce. The other bottle on this shelf is eight ounces for two dollars ninety-eight, or thirty-seven cents an ounce: this is twenty-seven times the price per ounce of powder
Functions
Intended for use with construction MARKERS and marking pen systems rather than a chalk reel — deep-hole marker pens, an Ox pencil, Pica pencil systems and a Tracer TrueShot chalk marker are all named. That is the real distinction on this shelf: a one-ounce bottle with a narrow neck fills a marker cartridge, where an eight-ounce bottle is sized for a reel
Supplied
Two 1 oz containers, stated as a practical multipack and as a gift-ready set. The fifth of five bullets is the gift suggestion
Material
A formula stated optimized for consistent flow and visibility. No fineness figure, no grain size and no material description appears — and fineness is one of the five things this shelf's introduction compares
Reference and mounting
Recorded under the brand "Generic" with the reference US TAPE - DURAMRK - 76700. US Tape is a real layout-tool maker and DuraMark its chalk line; the Generic brand field is a marketplace artefact rather than the product

Sized for a marker cartridge rather than a reel
Compatible systems named: Ox, Pica of the marking pencils shelf, Tracer TrueShot, deep-hole pens
No color stated at all
Best for: Refilling a deep-hole chalk marker, once the color has been confirmed with the seller
Blue chalk sold as water-resistant and fade-resistant, which is the opposite of what the color convention promises.
Stated dimension or range
Eight ounces, at two dollars ninety-eight — about 37 cents an ounce. The other bottle on this shelf is two ounces for twenty dollars thirty-seven, which is ten dollars nineteen an ounce: the same shelf, the same powder, a factor of twenty-seven
Material
Ultra-fine powdered chalk, stated to dispense smoothly and give an even coating with enhanced color payoff. Fineness is one of the five things this shelf's introduction compares, and it decides how cleanly the line lays: a coarse chalk leaves a fuzzy band, a fine one a crisp edge
Also stated
SEMI-PERMANENT, fade-resistant under direct sunlight and water-resistant, "measuring in at 1 on the permanence scale" — all of that on BLUE chalk. This shelf's buying tip says to use blue indoors as a default and keep red for outdoors, because on most brands the color tells you which grade is in the bottle. This bottle is blue and sold as surviving sun and water
Supplied
A fine-tipped nozzle stated to slot into chalk reel openings, minimizing spills. Klein says it can be used with ALL chalk reels — which on a shelf where one reel maker ties its tool to its own branded chalk is worth having in writing
Functions
Stated high-visibility on drywall, concrete, stone, wood and plastic. Plastic is the unusual one on that list and it goes with the water resistance: a chalk that will not bleed is a chalk that marks a membrane or a pipe
Reference and mounting
The product reference recorded for this listing is T5169GKLE while the title and the description both read CHLK8B. Two codes for one bottle, and CHLK8B is the one that matches the 8-ounce blue product

Thirty-seven cents an ounce, the cheapest chalk here by far
Eight ounces, which fills a reel many times
Blue chalk sold as semi-permanent, against the color convention
Best for: Lines on concrete, stone or plastic that must survive a damp week — not for a finished wall
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

A triangular barrel: it stays where you put it
Ten replacement leads, the most on this shelf
"Assorted color" leads, with no color named
Best for: A pencil that will be put down on a joist forty times a day and still be there
The only marker here that is not a lead — it sprays chalk two inches down a hole, and it works on grease.
Functions
It SHOOTS chalk up to 2 INCHES DEEP, stated, for marking where to drill through a hole that standard marking pens and deep-hole markers cannot reach. This shelf's introduction describes two geometries — a flat carpenter pencil and a thin lead in a long sleeve — and this is a third: nothing touches the surface at all, so there is no tip length to run out and no lead to snap
Supplied
250 BURSTS per cartridge, stated. It is the only count of MARKS on this shelf: every other marker publishes a lead count, which tells you how many leads and not how many marks. Two hundred and fifty is a day of bracket positions or a week of occasional ones
Also stated
Works on CLEAN, DIRTY, RUSTY OR GREASY surfaces, stated, and will mark at any angle. No lead does that: graphite skates off grease and will not take on loose rust, which is exactly the surface a steel fixing position sits on
Material
Bright GREEN chalk, stated high-visibility on any surface and easily removable, leaving no permanent marks. Green is unusual — the chalk shelf on this site deals in blue, white, red and black — and removability is the claim that lets it be used on a finished face
Stated dimension or range
Two inches of reach. No cartridge dimensions, no nozzle diameter and no hole size minimum appears — so which hole it will enter is not published, where one marker on this shelf publishes a 6 mm (0.24 in) tip
Reference and mounting
Named for drywall, concrete, brick, metal and wood, and for carpenters, masons and electricians. Refills: the chalk shelf on this site carries one-ounce bottles sold specifically for this kind of cartridge marker

Two inches of reach with nothing touching the surface
250 bursts published — a count of marks, not of leads
A burst is a blob, not a line: no scribing with this
Best for: Transferring a fixing position from a bracket onto the wall behind it, through the hole
The only marker here with a steel feed tube — which is the part a 2.8 mm (0.11 in) lead actually breaks in.
Material
Built from PP, ABS and STAINLESS STEEL, stated, with a stainless steel FEED TUBE described as making lead changes fast and easy. It is the only metal named inside any marker on this shelf, and the feed tube is the part that matters: a plastic tube wears oval and then the lead wobbles, which on a needle-nose tip is the end of precision
Functions
A one-click system dispensing 2.8 mm (0.11 in) lead, stated for clean consistent lines and built for repeat use. One click per advance is a small thing that decides whether you can feed lead with one hand while the other holds a square
Stated dimension or range
An EXTRA-LONG NEEDLE-NOSE TIP for tight precise marking, stated — with no figure. The marker beside it on this shelf publishes 6 mm (0.24 in) by 45 mm (1.77 in), so the comparison cannot be made: extra-long against what, and down a hole of what diameter, is left to the photograph
Supplied
Four leads, stated, and refillable with OX Tuff Carbon 2.8 mm (0.11 in) leads. Four is the fewest on this shelf, where the others ship six, seven or ten — and naming the refill product by name is the useful half: a 2.8 mm (0.11 in) marker with no named refill is a marker you guess refills for
Body and fittings
A built-in sharpener AND a belt clip, stated to keep the pencil on a tool rig or a pocket. It is one of two markers here with a clip rather than a holster, and the sharpener is in the body rather than in a separate part to lose
Also stated
Marks on wood, steel, tile, concrete and stone. No lead HARDNESS and no lead Color is published — the Tuff Carbon name suggests graphite, and this shelf's introduction says graphite disappears on dark stone, which is on OX's own list of surfaces
