A modular tool for imparting profile characteristics into fluent cementitious material. The tool has an elongated base forming a permanently fixed blade, and at least one handle. The blade is configured to act as a dovetail to which any of several modular blades may frictionally fit in removable fashion. The fixed blade forms a deflector disposed to deflect removed cementitious material away from the handles. Other blades may fit by peg and socket engagement. The tool may have detachable rollers enabling the tool to advance at a controlled elevation along a wall being formed and shaped. A slide block may be arranged to engage the rollers so as to adjust their position on the tool. The tool may have integral bubble levels.

1. A modular tool for imparting profile characteristics into fluent cementitious material, comprising: an elongated base having a platform and a permanent blade fixed to the platform, which said platform and permanent blade collectively form a dovetail for engaging other components of the modular tool projecting from the platform, and at least one principal handle projecting from the platform;a deflector disposed to deflect cementitious material waste which has been scraped by the permanent blade from the fluent cementitious material away from the at least one principal handle wherein the deflector is at the proximate end of said permanent blade;at least a first removable blade which is engageable with the dovetail of the platform and the permanent blade, wherein the first removable blade has opposed canted walls joined to a central panel which collectively form a socket which envelops and is retained on the dovetail;an accessory device usable with the modular tool; anda groove extending along at least part of the length of the elongated base, and a block slidably mounted within the groove, wherein the block comprises a connector for receiving and removably retaining the accessory device, wherein said accessory device slides on the permanent blade thereby changing the blade profile. 2. The modular tool of claim 1, further comprising a lock disposed to releasably hold the block at a selected position along the groove. 3. The modular tool of claim 1, wherein the accessory device comprises a roller arrangement further comprising a roller mounted on an axle, and wherein the axle is dimensioned and configured to connect to the block of the elongated base. 4. The modular tool of claim 3, wherein the roller arrangement comprises at least two rollers arranged in tandem so as to be able to roll along the same flat surface. 5. The modular tool of claim 1, further comprising a second removable blade which is mountable to the modular tool by slidably surrounding and engaging the dovetail of the platform and the permanent blade, which said second removable blade has a configuration which is different from that of the first removable blade, wherein the second removable blade has opposed canted walls joined to a central panel which collectively form a socket which envelops and is retained on the dovetail. 6. The modular tool of claim 1, further comprising a removable step forming blade having a stepped configuration and a connector for removably engaging the dovetail of the platform and the permanent blade, wherein the step forming blade has opposed canted walls joined to a central panel which collectively form a socket which envelops and is retained on the dovetail. 7. The modular tool of claim 1, further comprising a removable groove cutting module for forming a groove in an upwardly facing surface of the fluent cementitious material, wherein the groove cutting module is attached to the tool by a peg, comprising an attachment arm comprising a first leg bearing a connector formed at one end of the first leg of the attachment arm, a second leg disposed at a perpendicular angle to the first leg, the second leg having a proximal end joined to the first leg, a distal end, and a cutting blade fixed to the distal end of the second leg and arranged to project downwardly when the modular tool is held in a vertical orientation. 8. The modular tool of claim 1, further comprising a removable trough cutting module having a trough cutting blade and a connector which is removably engageable with the platform of the modular tool, wherein the trough cutting module has opposed canted walls joined to a central panel which collectively form a socket which envelops and is retained on the platform. 9. The modular tool of claim 1, further comprising a first bubble level oriented to have a longitudinal working axis disposed perpendicularly to said longitudinal axis of the platform of the modular tool. 10. The modular tool of claim 1, further comprising a second bubble level oriented to have a longitudinal working axis disposed parallel to said longitudinal axis of the platform of the modular tool. 11. The modular tool of claim 1, further comprising a third bubble level which is angularly adjustable relative to the platform of the modular tool, and a lock disposed to releasably hold the third bubble level in a selected angular orientation on the platform of the modular tool, wherein said lock comprises of a setscrew. 12. The modular tool of claim 1, wherein the at least one principal handle comprises at least two principal handles each of which projects from the platform. 13. The modular tool of claim 12, wherein the at least two principal handles occupy a plane which extends along the length of the platform. 14. The modular tool of claim 13, wherein one side of the platform which is opposed to the permanent blade is rounded in end view, and is dimensioned and configured to serve as an auxiliary handle, and wherein the at least two principal handles are oriented to present a hand gripping position which is at a generally right angle to the hand gripping position presented by the auxiliary handle. 15. The modular tool of claim 1, further comprising a slip-on cutting plate connector which is removably engageable with the platform of the modular tool. 16. The modular tool of claim 1, further comprising a platform that is adjustable in length. 17. The modular tool of claim 1, further comprising a crescent shaped cutting device for cutting a radius.
