Methods, systems and components for paper trimmers cut paper placed on a planar base using a blade that is moved transversely across the paper. A recessed cutting track containing a desired cutting pattern is inserted into the planar base and a counterpart guide track suspended thereover. A blade assembly is inserted through a channel in the guide track with the cutting blade residing in the counterpart channel in the cutting track. Material to be trimmed is placed between the recessed cutting track and the guide track. As the blade assembly is directed along the length of the counterpart channels, guides on the blade assembly interact with the channel and cause the cutting blade to rotate, cutting along the path of the channel. Desired cuts are made by selecting appropriate interchangeable cutting tracks and counterpart guide tracks.

1. An apparatus for trimming sheet material, comprising: a planar base;at least one a removable cutting track having an upper surface coplanar with a surface of the planar base and a defining a blade receiving channel having a selected pattern formed in the upper surface;a removable guide track positioned above the at least one cutting track, the guide track having a first channel in a top surface of the guide track substantially matching the pattern of the blade receiving channel and a second channel also substantially matching the pattern of the blade receiving channel, the first and second channels being substantially aligned with the blade receiving channel and extending through the guide track, the second channel being more narrow than the first channel to define a planar surface between the first channel and second channel extending along and adjacent to the second channel;a blade assembly comprising an outer housing, a cutting blade having a cutting surface slanting upwards from a lower leading edge to an upper trailing edge and one or more channel guides adjacent the cutting blade, the cutting blade being pivotably mounted in the outer housing blade assembly with the cutting blade being rotatable around an axis parallel to a longitudinal axis of the cutting blade, the one or more channel guides positionable within the second channel when a bottom surface of the blade assembly contacts the planar surface of the guide track. 2. The apparatus of claim 1, wherein the one or more channel guides adjacent the cutting blade are disposed on a lower surface of a retractable inner housing that at least partially surrounds the cutting blade, the inner housing being biased toward the cutting edge of the cutting blade. 3. The apparatus of claim 2, wherein the inner housing is retractable into the outer housing upon insertion into the first channel, with the cutting blade at least partially extending through a distal end of the inner housing and beyond the one or more channel guide. 4. The apparatus of claim 3, wherein the outer housing further comprises a collar having an enlarged outer rim that at least partially surrounds the inner housing, the outer rim positioned within and slidable along the guide channel with the first channel adjacent the collar to maintain the housing relative to the guide track while cutting. 5. The apparatus of claim 4, wherein the one or more channel guides comprises a pair of channel guides each forming a protrusion on the lower surface of the inner housing having an inner edge parallel to the cutting blade and an outer edge with a tapered front portion and a tapered rear portion, such that as the inner housing is slidably moved relative to the guide track, the tapered front and rear portions of each channel guide interact with a wall of the second channel, causing the inner housing and the cutting blade to rotate relative to the outer housing thus allowing the cutting blade to move along the second channel without cutting into the second channel. 6. A paper trimmer assembly comprising: a cutting track having a planar upper surface and a receiving channel formed in the upper surface, the receiving channel defining a selected pattern;a guide track positionable over the cutting track, the guide track defining a first channel substantially matching a shape of the selected pattern and extending through the guide track;a blade assembly comprising an outer housing, an inner housing biased within the outer housing and a cutting blade pivotally mounted within the outer housing, the outer housing having a bottom surface engaging the guide track and the inner housing having at least one blade guide disposed on a distal end thereof, the at least one blade guide positioned proximate the cutting blade and within the first channel when the bottom surface engages the guide track and the inner housing is retracted relative to the outer housing to expose the cutting blade, the at least one blade guide guiding the cutting blade through the first channel and preventing the cutting blade from cutting into the first channel of the guide track. 7. The assembly of claim 6, further comprising a blade holder having an elongate, substantially cylindrical shape with the cutting blade extending from a first end of the blade holder, the outer housing further comprising a receiving socket having a generally cylindrical shape for receiving a second end of the blade holder and allowing the blade holder to freely swivel therein. 8. The assembly of claim 6, wherein when the bottom surface of the outer housing is forced against the guide track and the at least one blade guide is inserted into the at first channel, the inner housing moves from a first, fully extended position in which the inner housing surrounds a distal end of the cutting blade to a second, retracted position to at least partially expose the cutting blade through a distal end of the inner housing beyond the at least one channel guide. 9. The assembly of claim 6, wherein the at least one blade guide comprises a pair of blade guides defining a blade slot therein between, each blade guide disposed on an opposite side of the cutting blade when the cutting blade extends through the blade slot and the pair of blade guides are positioned within the first channel to guide the blade through the channel while cutting. 10. The assembly of claim 9, wherein the pair of blade guides each comprise a protrusion on a lower surface of a retractable tube assembly having an inner edge parallel to the cutting blade and an outer edge with a tapered front portion and a tapered rear portion, such that as the blade assembly is slidably moved in the guide track, the tapered front and rear portions of each blade guide interact with a wall of the recessed channel, causing the retractable tube assembly and the cutting blade to rotate. 11. The assembly of claim 6, wherein the guide track further defines a second channel circumscribing the first channel and substantially matching a shape of the selected pattern, the second channel partially extending into the guide track to form a recessed planar surface around the first channel and wherein the outer housing further comprises a collar surrounding said inner housing, a distal end of the collar engaging the recessed planar surface and having a width to substantially match a width of the second channel, engagement of the collar within the second channel guiding the outer housing along the second channel as the collar is slid along the second channel. 12. The assembly of claim 11, wherein the collar further comprises an enlarged rim on a distal end thereof and wherein the second channel is spaced from the recessed planar surface to form a guide channel therein between, the enlarged rim having a width that is greater than a width of the second channel so that when the enlarged rim of the collar is positioned within the guide channel, the outer housing is retained relative to the guide track and is allowed to slide relative thereto.
