Keson CP2 Carpenter Pencil Sharpener

How can one sharpen a carpenter’s pencil? The International Arrivals sharpener didn’t quite seem to do it. Here is another attempt.

From Keson, it is a bright yellow plastic block with four blades. The pencil is placed in a slot (blue plastic) and one slides the pencil back and forth, the wood being sliced away. One end and pair of blades is for the long edge of the pencil, and the other end and blade pair for the short edge.

Does it work? Well the one I bought is resold by General Pencil, and includes a General Sketching pencil. They have a nice illustration showing how to use the pencil:

It does what it claims, creating a nice wedge of lead. Yet there are some other pencils out there – such as the International Arrivals – which don’t fit in the blue slots. Some European oval pencils (I tried a Viarco) are too loose and slide around. Others from Lyra are too large to fit. The Mastercraft and Faber-Castell pencils aren’t ideal fits either.

As well, one should be aware that this sharpener emits wood and graphite residue on both sides – it is very messy.

The above issues noted, it seems like the best sharpener available for pencils that it can accommodate.

The carpenter pencil has a claim on being the original pencil. The oldest known existing woodcase pencil is a carpenter pencil, seen here at the Faber-Castell website.

This pencil type is defined by the rectangular lead and housing.

Why the shape? The resistance to rolling off a sloped roof is the best explanation I’ve heard.

The ones I’ve seen for sale in Canada are typically octagonal – rectangles with the edges further chopped. But there is also a “chopped ellipse” version.

Hardware stores sell them. Seen here: Home Depot – note the FSC mark – I believe these are made by Musgrave, and were possibly the first pencil in a brick and mortar retail channel with this mark. Also, a couple of pencils from Canadian chain Home Hardware (headquartered in St. Jacob’s, Ontario).

Yet carpenters aren’t the only ones who have appreciated the shape of this pencil. Artists have also found the shape appealing. Here are a few pencils from Derwent, Faber-Castell, and General aimed at artists in the carpenter shape.

The Faber-Castell PITT Sketching 112994 in particular has an exceptional finish, with a thick clear vanish highlighting the natural woodgrain.

Some carpenter pencils from Europe have oval shapes. Additionally, they come in extra long versions. The pencil slat is a highly standardized commodity, and most pencils are about 175mm in length. Yet carpenter pencils also come in 240mm and 300mm lengths. I had read this online some while ago, yet was really surprised to see some in person. Non-novelty pencils made in nonstandard lengths are extremely rare.

Do you use these pencils, either as a carpenter or artist?

Kaweco acrylic leadholders

So what is a “leadholder”? The shrine is at leadholder.com. My abbreviated nutshell summary is that they are simple mechanical holders for wide diameter leads. Wide usually means 2 millimeters (mm) or more. Today, there are three common wide lead diameters – 2mm, 3.15mm, and 5.6mm.

If you aren’t familiar with these writing implements – and there is good reason to not be, since they won’t be found easily – it is my recommendation to try one if you are interested.

The simple part is the “clutch” – which clamps a lead with three jaws. Other variants are essentially mechanical pencils, which have an internal clutch, and a button to expel the lead.

2mm is the same lead diameter as most woodcase pencils. 3.15mm is a larger variant. Both are used in traditional drafting, architectural, and mechanical drawing disciplines. Since most of these professions switched to computer based drawing one to three decades ago (with notable holdouts), these pencils today are probably more in the domain of students learning traditional drawing methods, and artists. They are of course both perfectly useful for general writing.

5.6mm is definitely in the sketching and arts realm. At this diameter, various chalk and charcoal media can also be used. I like the sanguine and sepia refills that these pencils accommodate.

While thin lead (meaning 0.2mm though to 0.9mm) mechanical pencils may be the trend or norm – and many have sophisticated internal mechanisms to support their very fragile leads – wide lead pencils are the antithesis. Wide lead pencils are simple, and can be used freely in one’s hand, without any fear of lead breakage. And a thick lead can be used to create marks with considerable line width variations, or in a soft grade, to just sail across a large piece of paper! If you want to sharpen the point, there is no shortage of methods!

Kaweco acrylic leadholders

Kaweco, a brand of Gutberlet, recently introduced a new line of pencils. What makes this line special is that Kaweco is embracing all three wide lead diameters!

Sold in five basic colours, the blue series is shown here. I bought these at retail, and they are a great example of the benefits of the brick and mortar store. Online, all the colour variants seemed good to me – yet thank goodness I didn’t buy them online, because some were not at all appealing to me when I saw them in person.

The 2mm version is a cap button advance mechanical pencil, while the 3.15 and 5.6mm versions are clutch leadholders. The 5.6mm pencil additionally has a sharpener inside the cap.

The pencils are highly unified in appearance, yet each differs – the tip, the cap, and of course the lead.

They are budget priced writing implements which perform without problem, and have a finish just as sophisticated (excepting the removable clip) as far higher priced alternatives.

Highly recommended.

My thanks to isu for linking “Globe” with “Chikyu”. Here are some vintage Chikyu 8380 pencils. You can observe the globe logo. The pencils are bound in twine, and enclosed in a cardboard box.

Though 2H is too hard a grade for my typical pencil use, they were difficult to resist. I’m not going to find these at the local market!

I regret that I can’t say much about the manufacturer. Defunct? Merged?
