Graphite Pencils, Mechanical Pencils, and Leadholders Collection Picture Review

To balance the previous brush pens review, it seemed only fair to dedicate a few shots to the humble graphite drawing tools. Click on the pictures for further note details in my Flickr album.
In the 2 mm leadholder category, my current favorite and permanent fixture in my daily sketching tool case is the Mitsubishi Uni-ball F leadholder. Solidly constructed, well-designed push button, really comfortable to use, and with its slightly wider hexagonal brown barrel body with gold lettering that I really like. Since it lacks a built-in lead pointer, the KUM Lead Pointer for 2mm and 3.15mm lead, with sand paper & sponge pencil-tip cleaner is also a permanent component of my regular sketching kit. The Uni-ball F 2 mm graphite lead refills are very strong, hold their point for a long time, and yield nice lines that can be gradated from gray to dark with virtually no smearing. Quite possibly my favorite graphite grade for initial sketching and doodling.
For the larger 5.6 mm leadholders, Cretacolor produces several sturdy versions with metal clutch jaws, ergonomic design, and natural wooden finishes. The only one I would avoid would be the cheap plastic version that feels rather flimsy and tends to break under pressure. The 5.6 mm KUM lead sharpener comes in real handy since only the brick red ergonomic leadholder features a built-in lead pointer in its push button cap.
For wooden pencils, I am particularly fond of the Mitsubishi Hi-Uni pencils and have a good selection of pencil lengtheners to use them efficiently down to their short stubs. The Hi-Uni graphite is very consistent, non-crumbling, darker than corresponding grades of graphite of other brands, and glides smoothly over the paper surface (since they probably have a little wax in their formulation). Still, any of the brands pictured above will provide good reliable service and will be a joy to use especially the Tombo Mono, Mono 100, and Caran D'Ache Grafwood and Technalo pencils. Caran D'Ache graphite seems particularly smear resistant up to the 3B grade of softness.
The 3.15 mm leadholders, the Lamy Scribble and Wörther Shorty Pencil, are compact and sturdy choices that would fit nicely on any pocket. But since they and their refills are rather hard to find, I tend to limit their use for home studio especially after losing a Shorty Pencil during a trip to Peru.
