The critical loss of thousands of acres of shoreline, beaches, and wetlands each year is due to the simple loss of one grain of soil, silt, or sand, one grain at a time. The use of very thin precast concrete trunated conical sections, or 'beach-cones' installed with interlocking leak-resistant interstitial 'wave-blocks' in a simple geometric pattern, 'reverse' the daily cycle of build-up and erosion by accelerating the 'build-up' and preventing the recurring 'wash-out' of sandy material picked up and carried out by retreating waves. The beach-cone geometry smoothly absorbs the energy of the sand-carried waves, dispersing the energy of the wave and retaining the material deposited into the center of the 'beach-cones'. This process begins at the next 'high-tide' after installation. The critical erosional effect of wave 'undertow' is eliminated. In addition, the blockage effect of a row of beach cones builds up a new 'beach' on the shore-side of the installation when the 'cones' are installed at the water's edge at low tide.

A bivalve shell opening blade is fixed by an end to a handle and has a pointed, oppositely disposed free end extending forwardly therefrom. The blade is angularly disposed to the handle so as to fall in aligned continuation of the user's forearm when grasping the handle with free pointed end forward. The blade is offset from the handle for increasing hand leverage in opening the bivalve shells, and the angular disposition of the blade in alignment with the forearm maximizes blade point insertion force between shells and minimizes hand to handle friction and reduce muscular fatigue and blisters in use.

Two nested half cylinders, having a concentric axis and closed ends, are pivoted together on aligned pivot pins mounted in the closed ends and on the concentric axis. The nested half cylinders are actuated to pivot 90 degrees oppositely around the concentric axis and aligned pivot pins to close non-compressively around free flowing granular material in a closed cylindrical hoist bucket, thereby saving the additional weight and strength of material and the actuating energy therefor required for compressive loading of hoist buckets having off center or non-concentric axis of pivot. Additionally, the non-compressive loading does not move the granular material nor overflow the closed cylindrical hoist bucket to pollute the environment with dust therefrom.
