I purchased this as a Christmas gift for my husband who already owned a multimaster. Since it has become his standard tool, I decided to purchase some accessories he could use. There was just so much to choose from, it took a while. This straight cutter blade is perfect for oncoming jobs he has in our house alone. The blade is sharp on both sides and makes a smooth and clean cut on the sealants in our bathroom. He will be using it on all three of our bathroom remodels. I can't think of any reason this can't be used on other projects besides sealants. Well constructed. Great buy.
