Abstract: A dual-bladed multi-tool device for oscillating a pair of blades in opposite directions to facilitate a user in cutting materials includes a housing coupled to a pair of blades. The pair of blades includes an upper blade with an upper blade coupling end positioned within the housing. An upper blade cutting edge is distal to the housing. The upper blade cutting edge is sharpened to cut an object. A lower blade is positioned beneath the upper blade. The lower blade has a lower blade coupling end positioned within the housing. A lower blade cutting edge is aligned with the upper blade cutting edge. The lower blade cutting edge is sharpened to cut the object. A drive assembly coupled to the housing moves the upper blade cutting edge and the lower blade cutting edge in opposing directions to facilitate the user in cutting the object with the pair of blades.

Abstract: The invention provides a writing aid comprising a contoured surface having a plurality of relatively depressed surface portions and raised ridges or surface regions at least partially surrounding each depressed surface portion at a level differing therefrom by an amount rendering transition between a ridge or region and a depressed portion tangible to a person through a hand-held writing implement traversing the surface. The contoured surface may be provided by embossing writing paper or embedding threads therein, or may be provided on a substrate or backing sheet for a piece of plain paper.

Abstract: The invention relates to a spacing device for use with a ruler or other straightedge to aid handwriting of a neat and tidy appearance. The device comprises a resilient spacing member mounted on or in a writing implement and adapted to maintain under a first degree of manual pressure a predetermined distance between a writing point of the writing implement and an edge of a stationary ruler device positioned on a surface to be written upon, said spacing member being movable under a second, increased, degree of manual pressure to reduce the distance by a predetermined amount.
