E+M Cube 5.5 mm Lead Sharpener - Maple

A good lead sharpener. I like to use this product. It is a bit expensive though.

Very compact, elegant looking, and efficiently restores sharp points on 5.5 and 5.6 mm leads. Word of advice: I would recommend to use it exclusively for graphite leads to maximize the useful life of the sharp blades. I have prematurely clogged and dulled built-in lead pointers sharpening dry sanguine and charcoal drawing leads.

Stick to lead!
I love the little cube shape and color of this sharpener. I plugged it up sharpening a oil sanguine lead, wish I'd read the other review here first. But some smashing it on a hard surface cleaned the clog out quickly. After that I've used it with dry leads only and it has worked well since then.

This creates a a very durable short squat point. It's great as part of a sketching kit.

This is a great lead pointer. I use it for my Creative Mark clutch pencil. Even though it is a 5.5mm sharpener, it still sharpens 5.6mm leads really well. The black paint on it is very nice and doesn't look like it will scratch off. Although, I really wish it had a little opening in the back somewhere to empty out the shavings. I have had to tap the back of it several times to get all the shavings out, which is kind of annoying. It sharpens the lead to a very accute point, like some pre-sharpened 2mm leads. Although it works really well, it would be better if it produced a longer point.
