RTC Stumpy Joe Mini Trowel — Big-Trowel Control in Tight Spaces There's always a corner, a cabinet edge, or a tub surround where a full-size trowel simply won't fit — and forcing it there gives you sloppy coverage right where it's hardest to fix. The RTC Stumpy Joe Mini Trowel is built for exactly those spots. Its rigid steel blade transfers pressure cleanly for controlled shaping and feathering, so you can smooth ridges, touch up coverage, and pack mortar into small gaps with real precision. It's the natural running mate to the full-size Comfort Grip trowel — big blade for the field, Stumpy Joe for the tight stuff. Keep both clean with the Trowel Cleaning Brush. Why Tile Pros Choose It Reaches tight spots: Corners, cabinet edges, tub surrounds, wall cavities Controlled pressure: Rigid steel blade shapes and feathers cleanly Versatile: Smooth ridges, touch up coverage, pack small gaps Precise micro-adjustments: Big-trowel control at mini-trowel size Durable: Built for daily jobsite use Punches above its size: The little blade that saves the tricky cuts Pro tip: Use Stumpy Joe to back-butter small cuts and to feather coverage right up to an edge where the big trowel would drag — the rigid blade lets you key the mortar without gouging. Keep it clipped in the bag; you'll reach for it more than you'd expect.
