<p>With a heavy-duty carbide blade and carbide on both edges of its concave trimming face, the Ultimate Mash Hammer is the most wear resistant Trow & Holden stonecutting hammer. This hammer will split and trim the hardest types of stone and require less regrinding than traditional steel stonemason's hammers. </p> <p>When the working edges of the carbide begins to show wear, the concave trimming face can be easily dressed with the same 6in or 8in silicon-carbide grinding wheel used to grind the blade.</p>
