Abstract:
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; and a 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.
