The Koh-I-Noor Hardtmuth 5311 is a 5.6mm clutch pencil. It costs about £13 in the UK. I picked this one up second-hand from eBay.
It’s quite a heavy pencil. I suspect it’s made from brass but I can’t be sure. It’s built like a tank. You will never need to worry about breaking it.
The clip is a strong wire loop and is held in place with a bolt. It’s firmly sprung and performs its function well.
The pushbutton includes a lead pointer which works a treat.
The lead is held firmly in place. The lead this came with is great – nice and smooth and dark. I don’t know if this was the original lead, though. There are three indents running along the length of the barrel and this makes it easy to hold the pencil firmly and, also, comfortably.
This is a pencil that means business. It’s heavy and solid and strong and, well, really rather manly. If you tried to use it to sketch a pretty little flower it would implode. It’s a pencil to use in the workshop, while drinking beer and designing a shed.
