Bugaboos are designed for shallower cracks. They are bent and precision-ground for a plethora of possible thin-crack placements.

Bugaboos are a slightly beefier version of the Knife-blades. They both have ground-tapered blades resulting in a consistent blade shape - optimum for both strength and holding power.
