Another tool that I reach for often is a spoon/spatula shaped stainless steel modeling tool. Perfect for applying a dab of clay just where you need it, then...
smearing it out to blend in.
What I find so useful is the soft curve of the head of the tool, it allows the clay to feather out softly beneath your touch, rather than leaving a hard edge. You can also roll the tool to very precisely place or compact a small area of clay. Use the sharp edge to carve or inscribe into the clay. When dipped in a bit of solvent the spoon shaped head becomes very useful in smoothing and burnishing the clay.
As with the serrated loop tool that we looked at earlier in August, there are many different sizes and shapes of tools that fall into the general category of "spatula". This one is 6.5" long, the spatula head is about .5" at it's widest, and is marked "euclids #61" available at Sculpture Depot in their Stainless Steel Detail Shaping Tools section.
And oh yes, the pointy bit at the other end is rather handy too!
