The multi-tool assembly further includes a blade which is partially disposed within the housing and which projects out of the first longitudinal end of the housing. The housing has a slot which opens to the second longitudinal end of the housing and at least one tool engaging element disposed at least partially within the slot of releasably securing a tool in the slot at the second longitudinal end of the housing such that the tool projects out of the second longitudinal end of the housing. ## Claims ### Claim 1 A multi-tool assembly, comprising: a housing which extends between opposing first and second longitudinal ends; a blade that is partially disposed within said housing and which projects out of said first longitudinal end of said housing; said housing having a slot which opens to said second longitudinal end of said housing; at least one tool engaging element disposed at least partially within said slot for releasably securing a tool in said slot at said second longitudinal end of said housing such that the tool projects out of said second longitudinal end; said housing including a pair of cover elements that are joined with one another with a screw; said screw extending through said housing and projecting therefrom with a point for rotating said housing about said point; and said housing further including a plurality of recesses that are spaced longitudinally from one another and from said screw for holding a writing utensil in a direction parallel to said screw for drawing circles around said screw. ### Claim 2 (depends on 1) The multi-tool assembly as set forth in claim 1 further including a pencil and wherein said at least one tool engaging element secures said pencil within said slot. ### Claim 3 (depends on 1) The multi-tool assembly as set forth in claim 1 wherein said tool engaging element is a set screw. ### Claim 4 (depends on 3) The multi-tool assembly as set forth in claim 3 wherein said set screw has an enlarged head for manual threading and unthreading by hand. ### Claim 5 A multi-tool assembly, comprising: a housing which extends between opposing first and second longitudinal ends, said housing having a pair of sides and a front and a back, said housing being made of two cover pieces which are fixed together, and said housing presenting an open interior between said cover pieces; a blade that is partially disposed within said housing and which projects out of said first longitudinal end through an opening formed between said cover pieces; at least one of said cover pieces of said housing presenting a slot which opens to said second longitudinal end of said housing; a tool engaging element which extends through one of said sides of said housing and into said slot for releasably engaging a tool in said slot; said housing including a screw joining said cover pieces of said housing together and extending past said housing to a point; and said housing presenting at least one recess which is spaced longitudinally from said screw by a predetermined distance, said recesses being shaped to receive a writing utensil and hold the writing utensil in a direction that is generally parallel to said screw for drawing circular shapes by spinning said housing around said point of said screw. ### Claim 6 (depends on 5) The multi-tool assembly as set forth in claim 5 and wherein said at least one recess in said housing is further defined as a plurality of recess which are spaced longitudinally from one another by predetermined distances. ### Claim 7 (depends on 5) The multi-tool assembly as set forth in claim 5 wherein said tool engaging element is a set screw. ### Claim 8 (depends on 5) The multi-tool assembly as set forth in claim 5 wherein said at least one recess is shaped to receive a carpenter's pencil.
