There are plenty of ways to have your scotch or whiskey on the rocks while reducing dilution. There are cubes of stone or metal, orb molds of ice, and now a wedge. The Whiskey Wedge by Corckcicle is a great alternative to the ice spheres, as it melts slower, but will still gently dilute your spirit of choice just enough to allow for the added water to open up more of the flavor and aroma hidden inside your gain based liquor. Our pro tip: make sure you have a squared rocks glass, otherwise this mold will not fit.
