Drip Tubing V-Groove Square-Cut Block
This is a bench block for squaring the ends of drip-irrigation poly tubing before you push it onto barbed tees and elbows. It has a 90° V-groove 22 mm wide for 1/2 in poly tubing and a 10 mm groove for 1/4 in tubing, and both are crossed by a 1.2 mm utility-blade slot. A crooked cut is the usual reason a new fitting leaks or splits. The V-grooves hold any tube diameter, so they work across the 15–18 mm OD spread of 1/2 in drip line from different brands. The block is 80 x 44 x 22 mm.
Caulk Nozzle 45° Bead-Size Cutting Guide
This 100 x 30 x 36 mm block has a 45° knife ramp and five sizing holes for common caulk bead sizes: 1/8, 3/16, 1/4, 5/16 and 3/8 in (3.2–9.5 mm). Push a cartridge nozzle up through a 13 mm bore until it jams in the 3.5 mm sizing land, then slice flush along the ramp. You get a clean 45° opening at the bead size you picked, every time, with no guessing on a tapered tip.
