One day we were at a nearby restaurant and I was looking at the wine list. Normally I don't order wine at restaurants unless it's a special occasion, but, just out of curiosity, I always look at the list, and find my eyes wandering towards the cheapest item, which is invariably house wine. It was $6. I wished that instead of listing wine, they listed this pencil. Surely I would not hesitate to order it, as it is, in my opinion, a much better value than a glass of wine for the same price. It will last a lot longer too. And this is a really nice pencil, as you will see from this review at Pencil Talk: Pencil Talk review of the Mitsubishi Super DX 8B pencil Its outward appearance, that is, its lacquered finish, gold lettering, banding, and 4mm core (standard pencil leads are half the diameter*) distinguish it from ordinary pencils, and even from the venerable Hi-Uni from the same maker. In fact, you can hardly talk about these Super DX Hi-Uni pencils and the regular Hi-Uni pencils in the same breath. Pencil experts may detect hints of cherry in the finish, and a flutter of cedar scent from the business end. In Japan, its nickname is the "brush pencil" because its thick, dark line, huge core, and smooth writing (due to a specially formulated oiled grahite) are popular for Japanese calligraphy known as "shodo". Yes, $6 is quite expensive for a single pencil, but I'll take it over a single glass of house wine any day of the week. Comes in two grades: 8B and 10B (the higher numbers are darker and softer). * Aside from what seems to be a different lead formulation, here's an argument for why this pencil is actually a good value relative to the standard Mitsubishi Hi-Uni: The Hi-Uni 8B can be found on Amazon for about $1.84 per pencil, when bought by the dozen. It has a standard 2mm core, while the DX has a 4mm core, and thus, more lead to write with. In this case, it has 4 times the amount of lead, but costs only 3.26 ($6 divided by $1.84) times as much! It's like getting 23% more lead for free. Here's the math: Surface area of circle = pi(r^2). Thus, Area of a 2mm core = 3.14(1^2) = 3.14(1) = 3.14 sq mm Area of a 4mm core = 3.14(2^2) = 3.14(4) = 12.56 sq mm Therefore, 12.56 / 3.14 = 4 times the surface area of a 2mm core Price: 4 times the lead divided by 3.26 times the price = 123% (23% more)
