I believe I purchased my pencil openstock at the Dick Blick in Savannah, Georgia, a couple years ago, so much of what makes it so special may have degraded over the year. If you were to purchase a new pencil, you can get two for $5.19 on Dick Blick. If you are a fan of wooden pencils, you may wish to take my review with a grain of salt, as I personally prefer mechanical pencils due to their ease of use.
I decided to go ahead and give the Sketcher a shot and put it to use during the OC Challenge to draw Naomi cosplaying as her favorite character, Katara from Avatar.
I personally found the Caran d'Ache to be a bit clumsy to use, but this is probably because I'm much more comfortable drawing with mechanical pencils than I am with using traditional wooden pencils. I do use black color pencils for thumbnail illustrations, gesture drawing, and doodling, but I usually keep several sharpened and within reach so I don't have to constantly stop to sharpen. Although the Sketcher is less waxy than Stadtler's non photo blue pencil, it isn't more crumbly or prone to breakage, although I did find it somewhat more difficult to erase than Color Eno's Soft Blue lead. This may be due to the age of the pencil's eraser, or just the quality of the eraser itself- I usually opt for vinyl erasers over those that come with the pencils.
I found that the nonphoto blue pigment built up much quicker than the Color Eno soft blue mechanical pencil lead, and made it difficult for me to refine shapes.
I was able to ink on top of the Caran d'Ache lead with little difficulty and no significant increase in drying time.
