Hapstone changed the design to be similar to the Leading Edge stone holders where the "slider" covers the top of the stone holder. This helps restrict the slider from angular change so it won't have as much of the rear part of the stone lifting problems as the first generation when the spring tension pushes against the stone.
The newest generation Leading Edge stone holders do not have a spring at all, has internal tracks/guides, has a slider covering the top, and tightens by screwing the handle in so the stone is 100% secure and level. The difference is that it is made of PLA thermoplastics but it is definitely a more secure stone holder than the Hapstone holder. The Leading Edge stone holder is also adjustable to accept a wider range of stone sizes, slightly longer and shorter than 4 inches, or even stones without any dovetail backing.
