This hammer works great on the Grover Pro-Musical Anvil. My problem is the price compared to what you get. I ordered this hammer thinking, "Well, it has the Grover name on it, so it must have something special to it. NOPE. This is just a typical jewelers hammer made by EruoTool with a Grover sticker on it. You can buy this exact same hammer at your local hobby shop or hardware store for less than $10. Just because you slap a sticker with your company name on an item, doesn't make that item worth more than it is. I love Grover Percussion products, but this really let me down.
