Koh-I-Noor Hardtmuth 5311 Mechanical Lead Holder
If mechanical pencils are your preferred type of writing utensil but you’ve had it up to HERE with those tiny lead sticks breaking…well, you might be applying too much pressure when you write — but if you’re not going to fix that, then you should look into getting one with a thicker grade of lead.
The 5311 by Koh-I-Noor is more accurately described as a “lead holder” than a true mechanical pencil, given the thicc-with-two-C’s 5.6mm x 80mm graphite leads it uses. This thing is solid as a rock, and it writes and sketches that way too. Go ahead and apply as firm a press as you like, because you’re not likely to break this lead even if you drop the entire utensil on hard ground.
There’s a sharpener built into the cap, revealed when you unscrew it. However, it’s admittedly a bit tedious to use, so I recommend getting a standalone sharpener that will do the job more robustly.
The Koh-I-Noor 5311 Lead Holder is $16 on Amazon.
