A finishing trowel comprised of a blade, a mounting and a handle, wherein the handle is hollow and has a square mounting hole for receiving a square mounting surface. A plastic handle is comprised of a durable inner core material and a grippable outer member. The handle\s inner core includes deformable ribs which axially line the mounting hole and provide a secure, lash-free fit onto the mounting surface over a broader range of manufacturing tolerances for the parts. The handle also includes an endcap which cuts into and seals the endcap against an outer grippable material upon tightening of a flanged nut onto the mounting. A lip extends from the handle and encompasses a portion of the mounting to facilitate increased torque transfer from the handle to the mounting and blade. The replaceable handle can also be formed of other grippable materials such as wood.

A trowel, comprising: a flat blade; a mounting affixed to the top surface of said blade, said mounting comprising a rib, a post extending upwardly from said rib, said post including a front surface, and a tang extending laterally from said post, said tang having a proximal section and a threaded distal section; a handle secured to said tang, said handle including (i) an outer grip member formed of a first thermoplastic rubber material and providing a grip surface of a first coefficient of friction with the user\s hand; (ii) a hollow inner core formed of a second plastic material and including (a) a mounting hole for receiving said proximal section of said tang; (b) a lip angled and rounded so as to provide a flush transition between said post front surface and said inner core, said second plastic material providing a surface having a second coefficient of friction with the user\s hand; (c) an end region, distal from said mounting hole and sufficiently thin so as to provide a deformable wall to axial pressure; (d) a radial channel within said end region; (e) an annular rim terminating said inner core; (iii) an endcap formed of a plastic material, said endcap including (a) an endcap hole for receiving said threaded distal section of said tang; (b) a conically shaped receiving surface surrounding said endcap hole; (c) an inner rib structure having a plurality of inner ribs, wherein (1) each said rib includes a rib contact region for contact with said annular rim, said rib contact region pressing into and deforming said rim upon forcing said endcap against said rim and making sealing contact with said outer grip member; and (2) some of said ribs include a spring tab which extends outwardly and is received by said radial channel of said handle end region; (iv) an end nut threadable onto said threaded distal section of said tang for forcing said endcap against said annular rim.
