Very helpful 3 twists and the lead shows. Small so if you don’t put it in a bag or something you could lose it.

I like carpenter pencils because they don’t roll off the desk. This sharpener works perfectly.

I hada big box store brand sharpener I got for undera dollar and it did ok but good golly one had to work at it to get a half decent sharpen . I lost it . I saw this one and the price being 5x as muchI almost didn't buy it but I'm glad I did .It's about the same size as the elcheapo but works 10x better with no more effort than sharpening a thinner #2 pencil with a hand held sharpener . It also did 10x better of a job .Yeah I paid more but what a great value ! Well worth the cost !

It is painful sharpening square pencils. You whittle and the graphite breaks.I then found this sharpener. This makes sharpening carpenter's pencils much easier. You put the pencil into the end, it has an opening that is the shape of the pencil. The inside portion of the tool spins against the blade while you hold the outside. It carves off the sides and then you can get your pocket knife to finish the job. (you still have to use a pocket knife and try not to break the graphite but most of the work is done)I did find that this pencil sharpener also sharpens what I believe to be the ultimate carpenter's pencil. (It's not what you think) I just discovered it the other day.It is called "My First Ticonderoga" pencil. It is meant for young kids who cannot yet grip a thin pencil. Ignore that though, they have created the best carpenter's pencil ever. (or get one for you and one for your kid)The pencil comes with a sharpener (that can also sharpen crayons incidentally) and it is round so it is easier to sharpen and you don't have to use a pocket knife at all. You can use this higher quality Irwin sharpener on the My First pencil! The downside is that you lose the ability to sharpen crayons. (tradeoffs)The lead in the middle is very thick making it perfect for carpentry work. In fact, the lead (which is, of course, is actually graphite) is of higher quality than any of my carpenter's pencils. It shines when I make a line. I can see it with polarized sunglasses on better. Even on old wood that I am reusing, I can easily see the lines that I make.It has an eraser that will most likely never be used but just I consider the eraser a safety device. (not really, that is just a joke)If you work in the trade, you will probably get some ribbing for using a child's pencil. I know I have been getting a bit of grief from the people I have been doing carpentry work with, my wife and kid. It is totally worth it. (earplugs help with that too)If you are really concerned about it, you could scrape off the name and branding and paint it something manly like camouflage. That is a bit of effort but it is probably still easier than sharpening a traditional carpenter's pencil.I was so happy I discovered that pencil and I was also happy to find that this Irwin sharpener worked with it!The only downside is that the round pencils roll. Square pencils stay put. That is the only downside I can think of and it might be a big deal for some who are used to square pencils.I did shapen my square pencils with this though and it does work for that. Sharpen then use the pocket knife to finish the job if you don't break the graphite.I will mostly be using this for sharpening My First Pencils though.
