This thing is great. Tried it right away with Stabilo "All" 8400 series colored
pencils. They are very soft and notoriously hard to sharpen without breaking the
lead and this sharpener brought them to a long, fine point with little effort.
The ratcheting mechanism works great although I found the pop-up button to be
negligibly useful. The one design flaw I've found is that you can't access the
blade to clean it if it becomes clogged with a broken lead, but the fact that
breaking leads while sharpening doesn't really seem to be an issue so far that
might not matter. The chamber holds a fair amount of shavings, much more so than
other compact sharpeners I've owned. I'm not sure how long the blade will hold
up so i'll be ordering another one for my second drawing kit.
